We're well into our fourth day in five above 30°C, but around lunchtime a front passed that dropped the dewpoint from 22°C to 9°C. What a difference. It's still hot, but at least it's not so sticky. Walking home from trivia last night I practically swam through 25°C air with a 23°C dewpoint and lost two belt sizes along the way.

The Climate Prediction Center guesses that August will be cooler than normal, as will September and October. And I guess one week of every year we just have to take the heat. Today's dewpoint drop is very nice, though. It almost makes me want to spend more time outside. Maybe by October...

So far Chicago has had a milder-than-normal summer, with only a couple of over-32°C days and a lot of rain. Given our greenhouse gas emissions, that will change:

The NASA climate projections offer a detailed view of future temperature and precipitation patterns around the world at a 15.5 mile (25 kilometer) resolution, covering the time period from 1950 to 2100. The 11-terabyte dataset provided daily records and estimates of maximum and minimum temperatures and precipitation over the entire globe. It integrates actual measurements from around the world with data from climate simulations created by the international Fifth Coupled Model Intercomparison Project, or CMIP, which is a standard experimental protocol for studying the output of coupled atmosphere-ocean general circulation models.

The result? Pretty warm:

I won't be around to experience an average annual temperature around 30°C. Unfortunately, given the effects of climate change on our food and water supplies, not many others might be either.

Jeff Skilling at the Chicago Tribune updates us on the equatorial Pacific:

The current El Nino comes together against a backdrop of warming oceans and oceans which are growing more acidic as they observe mass quantities of CO2 produced through the burning of fossil fuels and the release of CO2 into the atmosphere this produces. More on the rate at which the planet’s oceans are warming here. It’s estimated that the warming which has taken place in the world’s oceans since 1990 is the equivalent of having exploded 5 Hiroshima strength nuclear bombs in the our planet’s oceans every second over the 25 year period. The warming oceans may be impacting the strength of the current El Niño. For more, click here.

What can we expect in the next few months? Most likely, increased precipitation in California, heavier than normal precipitation this fall and winter in the South, and a milder winter here in the midwest. However, with the ridiculously resilient ridge over the western U.S. and Canada, this year's El Niño could be completely different. Can't wait to find out.

Yes, Illinois was #1 in rainfall last month, making us the wettest state in the country:

The National Centers for Environmental Information (formerly NCDC) released their numbers for June, showing that Illinois did indeed have its wettest June on record with 236.2 mm (according to their calculations). That made Illinois the wettest state** in the US for the month.

**There are no statewide records for Hawaii. However, an examination of the four main sites in Hawaii indicate June totals that are far less than 9.3 inches.

Illinois, Indiana, and Ohio all had their wettest months in the 121-year record; Arizona, Pennsylvania, New York, New Jersey, Vermont, Maryland, Virginia, and New Hampshire had top-5 wettest months ever.

The weather patterns causing all this rain, by the way, are related to global warming, and similar to the patterns causing frequent polar vortices in the eastern U.S. Welcome to the future!

The weather's perfect, there are holiday parties, and possibly some hiking. So not much blogging this weekend. There was also a small Ribfest nearby, but aside from Rod Tuffcurls & the Bench Presses, kind of disappointing (especially the vendor who ran out of ribs).

Wednesday 1 July 2015

As feared, last month was the wettest June on record in Illinois, and the second-wettest month of all time:

The statewide average precipitation for June 2015 in Illinois was 242.1 mm, based on available data through June 30. That is 135.4 mm above the average June precipitation, and the wettest June on record for Illinois.

In addition to being the wettest June on record, it is the second wettest month on record for Illinois. Only September 1926 was wetter at 244.4 mm – just 2.3 mm higher.

Meanwhile, in Chicago, it was the cloudiest June in all 122 years of records, in part because we're covered in Canadian wildfire smoke making everything a little hazy.

On the other hand, it got up to 35°C in London today—and they don't generally have air conditioning over there. Yow.

People in Los Angeles talk about the "June Gloom," a common weather pattern that makes L.A. weather gloomy in the late spring. We don't typically have this phenomenon in Chicago. This month, however, is the gloomiest June ever here, with only 45.7% of possible sunshine through yesterday, and clouds today and predicted for tomorrow.

This month is already the fourth wettest month in Illinois history (and the wettest June in state history) with statewide average precipitation of 227.8 mm through Saturday. Much of the state is having more rain today, so it's reasonably likely that June 2015 will end as the second-wettest month in state history. We'll find out Thursday or next Monday when all the figures are in.

We Chicagoans are used to changing weather, and to some degree we enjoy it. We really dislike persistent stretches of unpleasant weather. Let's hope the weather changes in a few days. We're tired of the clouds and rain.

When the movers arrived at the former Inner Drive Technology World Headquarters yesterday morning, they remarked that it looked like I had everything organized well and they would hit their estimate. Mother Nature disagreed, giving us drenching rains that halted loading the truck for half an hour, and following up with this when we unloaded:

[T]he weather service issued a tornado warning for parts of central Cook County, activating sirens throughout Chicago, but no touchdowns were reported. That warning expired at 5:15 p.m. after the storm moved over Hillside and Westchester and weakened as it moved east.

A spotter at Midway International Airport reported seeing a funnel cloud about a mile east of the airport, heading east. There also was a report of a funnel cloud forming south of Millennium Park about 5:20 p.m., according to weather service meteorologist Bill Nelson.

I may have video at some point, and I still have some Italy photos to put up. And today, of course, is Parker's birthday, so I'll try to get a birthday portrait this evening.

Now I have to catch up on work.

A pile of Gulf moisture has arrived in Chicago making the otherwise-comfortable 22°C feel like a sauna. I'm using the day to do some planning for my next trip (11 days, 22 hours!) and move (28 days, 22 hours!), client work, and taking Parker to an interview of sorts at a new daycare facility. Yes, an interview: he has to play with the other dogs for two hours so they can decide whether to allow him to come back. I hope he passes.

Results from that, as well as a probably thunderstorm (unrelated), later today.

First, because NASA's reputation is such that climate-change deniers have difficulty refuting the agency, Republicans in Congress are trying to get NASA out of the discussion:

As has been widely reported, the House Science, Space and Technology Committee recently approved a bill that would cut at least $300 million from NASA's earth-science budget. This comes after the head of the Senate committee overseeing NASA claimed the agency should stop doing earth-science and focus only on space exploration.

Honestly, when it comes to getting the science of climate change right, who are you going to believe? A radio talk show host or NASA? The angry denialists in the comments section of this blog or NASA? The politician who says, "Well, I am not a scientist" or the scientists at NASA?

Then, closer to home, a group of residents in Chicago's Lakeview neighborhood really don't want a Whole Foods Market in their back yards:

The grocery giant's current Lakeview store, at 3300 N. Ashland Ave. opened in 1996 and is 31,500 square-foot—a speck compared to the labyrinthine, 79,000 square-foot Whole Foods located near North Avenue. That is why the company plans on opening up a 75,000 square-foot store one block away, at 3201 N. Ashland Ave. The building will feature 300 parking spots on the first floor and the basement, and a full store on the second story.

Speaking for the Melrose Street Concerned Residents, Tricey Morelli summed up the fears of the locals:

"Subconsciously, you see a big building like this and there's no windows into the building, so it makes you think, like, 'Why aren't there windows on the main floor? Are they fearful that someone's going to bash the windows? Is there going to be crime?' It kind of almost makes it look a little bit like a mean street."

This woman is speaking about a Whole Foods store in Lakeview, which has us confused. Are there roving bands of recent college graduates and moms with strollers running around, smashing windows and defacing property? We certainly can't discount the possibility.

I really don't understand what it's like going through life afraid of fantasies...

Yesterday's forecast didn't pan out exactly as plans. Afternoon rains held the temperature down to 26°C, so rather than being the warmest day since September 29th (28°C), it was the warmest day since...April 17th.

Today it's just soggy, and we're about to get a cold front. So I'm going to dash over to the nearest Whole Foods for lunch to make sure I get my steps in.

As for the concert, well, we sounded better than we did on Friday, but there were more people on stage than in the audience. That's one of the hazards of performing in Suburbistan. Our next concert is November 8th in Chicago, where we'll probably have much better turnout.

As I mentioned yesterday, we finally have a late-spring weekend in Chicago. It got up to 24°C officially at O'Hare yesterday; today's forecast high is 27°C.

Parker got a 3=hour, 12.5 km walk, while I managed 26,000 steps and 21.4 km of my own. And we just got back from another 5,000-step walk before he gets to do his second-favorite activity: a Ride in the Car!

Apollo's final concert of the season is this afternoon, too. I'm kind of sad not to see the chorus again until rehearsals resume mid-September. But there's a lot going on this summer, including moving IDTWHQ. Stay tuned.

Blogging might be spotty this weekend. After last night's concert, a group of us from the chorus went out and stayed out. Fortunately none of us seems to have any real responsibilities today.

Even better, the forecast calls for the warmest day of 2015 so far on Sunday, when we expect 27°C. That would also be the warmest temperature since September 29th.

So Parker and I may spend a good bit of time outside. Possibly I'll break last week's Fitbit record. Or possibly I'll just take a nap...

Parker and I walked about 10½ km yesterday, resulting in plenty of sleep and (probably) sore paws for both of us. We also got caught in a pneumonia front, in which late-afternoon cooling stops driving a land breeze and allows denser, cooler air from the lake to spread outward over the shore. Temperatures dropped from 18°C to 9°C in twenty minutes—unfortunately, the 20 minutes coinciding from our farthest distance from home. This bothered Parker a lot less than it bothered me, owing to his two fur coats, but fortunately I had an extra layer available. And I walk fast.

I also stayed away from Opening Night at Wrigley, the first regular game of the baseball season, in which the Cubs got their asses handed to them by the Cardinals 3-0. (They went 0-for-13 with runners in scoring position, too. Great work, guys.) The New York Times called the game "beginning their 107th year of waiting for a World Series title." Sounds about right.

The National Aeronautical and Atmospheric Administration (NOAA) reported today that the climatalogical winter of December 2014 through February 2015 was the warmest on record, despite what happened in the eastern United States and Canada:

During December–February, the average temperature across global land and ocean surfaces was 1.42°F (0.79°C) above the 20th century average. This was the highest for December–February in the 1880–2015 record, surpassing the previous record of 2007 by 0.05°F (0.03°C).

During December–February, the globally-averaged land surface temperature was 2.63°F (1.46°C) above the 20th century average. This tied with 2007 as the highest for December–February in the 1880–2015 record.

Even with record cold from Maine to Alabama, it was the 19th warmest winter in the Lower 48—in part because five states in the west experienced record heat and six more got into the 90th percentile.

Yesterday evening when I walked to rehearsal the temperature in Chicago was 22°C. Four hours later it was 8°C, and it fell to 2°C by sunrise.

This is what we call a "pneumonia front," especially when this sort of thing happens mid-day. People go to work or school dressed for warm weather and catch pneumonia on the way home.

Add to that the 46 km/h wind gusts out of the north and it's a banner spring morning here in Chicago.

Anthropogenic climate change may have permanently destabilized both the West and East Antarctic Ice Sheets, meaning the planet could experience 3.3 to 4.3 meter sea-level rises in the next few centuries. And even better, gravity will push more towards North America than towards anyplace else:

In the event of a collapse of the West Antarctic ice sheet, scientists have determined that the United States will receive moresea level rise than almost any other part of the world. (Granted, so will other countries in North America, like Canada and Mexico, which have considerably less global warming responsibility.)

In this case, West Antarctica is so large that it pulls the global ocean toward it, which slopes upward toward the ice sheet and the Antarctic continent in general. But if West Antarctica were to lose a substantial part of its ice, then the gravitational pull would relax, and sea level would actually decrease near the ice sheet even as it spreads and increases across the global ocean.

But not evenly. Instead, areas farther from West Antarctica would get more sea level rise, and North America and the United States might get more than any other inhabited place on Earth. “The water that had been held close to West Antarctica spreads out across the ocean,” explains Penn State glaciologist Richard Alley, “and we’re far enough away that we weren’t in the ‘pile’ that was held close to West Antarctica when the ice sheet was there and its gravity attracted the water to make the pile, but we get our share of the water from that pile when it spreads out.”

So possibly, a couple centuries from now, there will be an enormous dam protecting the Long Island Sound from the Atlantic, and Florida will be an artificial island somewhere near Miami. Good work, humans.

Apparently my last four weekends have been pretty busy. Once again I have almost no time to post anything, not least because it's sunny and 13°C, so Parker and I are getting ready to go hiking.

So here's a listicle. Generally I hate them, but this one from Inc. listing frequently-misused cliché phrases made me point to my screen and shout "yes, that!"

11. Baited breath
The term "bated" is an adjective meaning suspense. It originated from the verb "abate," meaning to stop or lessen. Therefore, "to wait with bated breath" essentially means to hold your breath with anticipation. The verb "bait," on the other hand, means to taunt, often to taunt a predator with its prey. A fisherman baits his line in hopes of a big catch. Considering the meaning of the two words, it's clear which is correct, but the word "bated" is mostly obsolete today, leading to the ever-increasing mistake in this expression.

I'm waiting with bated breath for the next bit of list bait to cross my Facebook feed...

Rebecca Leber at New Republic states the obvious:

The phrase, “believe in climate change” returns almost a quarter-million Google results. As McCarthy said, science is neither a faith nor a religion, yet the term belief pervades media and politics. Why do advocates so consistently play along with the climate-change-denier narrative?

Conservatives have long drawn comparisons between climate change science and a fervent religion. A 2013 National Review column articulated the parallels thus: “Religion has ritual. Global-warming alarmism has recycling and Earth Day celebrations. Some religions persecute heretics. Some global-warming alarmists identify ‘denialists’ and liken them to Holocaust deniers.”

Leber makes good points, but it's not a great article. I'm posting it because I agree with her main point, and also because it's an example of the slide in quality at TNR since they destroyed their editorial board.

Tom Skilling started his Explainer column today by depressing the hell out of me:

Chicagoans haven’t seen a temp above 8°C since late December. And a reading of 12°C or higher has been a no-show here since Nov 11th when the mercury last made it to 14°C. As if that’s not been bad enough, the city’s sat beneath a cover of snow that’s been at least 125 mm deep since Feb. 1—a run which moves into a 34th consecutive day Friday. Thursday’s bone-chilling and unseasonable -9°C high–a reading 14°C below normal and just 2°C shy of tying a 1901 record for max temp—only poured salt in the wound. It qualified as the coldest March 5th daytime high in 114-years. And, following Thursday morning’s lead, overnight temps [dipped] to sub-zero [Fahrenheit] levels over much of the metro area away from Lake Michigan one last time in the current cold siege–an arctic blast which has produced significantly below-normal temps for 22 consecutive days.

Yes, this has been our third really bad winter in five years. But it is March, so something has to change eventually right? Right:

[B]eyond this weekend and barring unforeseen changes going forward—the sudden appearance of a Chicago-bound backdoor cold front capable of turning winds off Lake Michigan’s icy waters would be an example—the area is in for one impressive warm-up by Tuesday, Wednesday and Thursday next week. It doesn’t signal that cold air or snow is completely finished for the season—history shows the area has been vulnerable to snows of some substance into April in some years— but it sure marks a major step in the transition from winter the the warmer days of spring.

How much warmer? Estimates by the four major weather models range from 28°C to—no kidding—41°C warmer than last night's -18°C low. Given that the lake is mostly frozen and we still have 125 mm of snow on the ground, the current forecast for The Daily Parker predicts 10°C on Tuesday and 12°C on Wednesday—warm enough to walk to work. And with above-freezing temperatures predicted from tomorrow forward, all that snow should melt.

Stay tuned.

Wednesday 4 March 2015

On only six occasions in recorded history has Chicago experienced a temperature below -18°C in March.Tonight could be the 7th:

A sub-0 reading at O’Hare by daybreak Thursday would be the latest a low temp has dropped below 0 [Fahrenheit] here in the 33 years—–since 1982. The -19°C reading being predicted is hardly a common occurrence so late in a cold season. In fact, of Chicago’s 1,041 sub-0 readings in 144 years of official temp records, only 6 have occurred beyond March 5th (Thursday’s date). And on a broader scale, only 12 of the 144 Marches on the books since official records began here in 1871 have managed one or more sub-zero temps.

But:

Daytime highs could register as much as 28°C warmer in a week

What’s to happen in the wake of the frigid late-season chill of the next two days is the most significant pattern change across North America since December. Major warming is projected. The pace of the warming will depend on the speed with which snow melts and on wind direction, since any “easterly” winds at this time of year deliver a very chilly brand of air off ice-cluttered Lake Michigan.

Oh, and we've had snow on the ground now for 34 days straight, which isn't a record but is unusual this late in the year. It's not the snow on the ground I find objectionable, either; it's having to keep a pair of shoes at the office and clomping to work wearing boots every day. I hope next week's warm-up finishes that phase of the year.

Also, we're pretty much sick of the weather here. February tied with 1875 for the coldest ever, at -9.7°C, and third-snowiest, with 681 mm. That last comes with a star as this was one of only 6 Februaries in history in which we had snow on the ground for the whole month.

Oh, and the forecast through our concert calls for significantly below-average temperatures until Sunday, except for Tuesday, when we'll have freezing rain and snow. Yum.

Depending on tomorrow's weather, this month might be the coldest February in Chicago history:

As of Friday morning, the average temperature for the month was -9.33°C, surpassing the average of -9.27°C in 1936 that is currently ranked the second coldest February, according to the National Weather Service.

Could Chicago see its coldest February ever? That record, an average of -9.67°C, was set way back in 1875.

Oh, and:

This month currently ranks as the third snowiest February on record with 671 mm recorded at O'Hare International Airport. The second snowiest February was back in 1896 with 706 mm, according to the weather service.

We're overjoyed, really, this is a great honor.

This morning's -10°C temperatures weren't that much better than yesterday's, but it still felt warmer, maybe because we got all the way up to -2°C by 6pm.

The sun may also have helped:

More cold coming. Spring, too, should be here in a couple of weeks months.

The temperature in Chicago hasn't gone above freezing for 12 days, and got down to -20°C only last night. So right now, at -2°C, and with the sun out, it feels positively tropical.

Unfortunately, the forecast doesn't show us actually getting above-freezing temperatures as far out as it goes. Medium-term forecasts also show below-normal temperatures all the way out through mid-March. And in the latest bit of good news, the Great Lakes are almost 86% covered in ice, close to the record of 94.7% set in 1979. For perspective, a year ago the lakes got up 93% coverage and the last ice didn't completely melt until June 12th.

So, we could be in for another chilly spring and cool summer, followed by (one hopes) a mild autumn, just like last year.

And because warmer temperatures to the west of us seem to have caused this pattern to emerge both last year and this year, it could become a permanent feature of north-eastern North America's climate.

Between rehearsals, work, and life, I haven't had a lot of time during the day to goof off keep abreast of world developments. So here's what got sent to my Kindle just today:

Yesterday was 17°C below normal in Chicago, the 8th consecutive day of frigid temperatures here, including a new record low maximum yesterday of -16°C. And while 19 states had record lows yesterday, western states are baking:

"Winter seems to have completely forgotten about us out here," Kathie Dello, deputy director of the Oregon Climate Service at Oregon State University, told the Associated Press. "If we could find a way of sending [the Northeast] snow out here, we'd really, really appreciate that."

- Las Vegas [had a] record high of 26°C, and Reno had its warmest Valentine's Day on record (as well as a record high) when the thermometer hit 23°C. Salt Lake City (16°C) and Pocatello, Idaho (13°C) broke their daily high temperature records on Valentine's Day as well.

- Phoenix has seen high temperatures in the 80s [Fahrenheit] since Feb. 5, with the exception of one Thursday which recorded a high of 26°C.

Thank a meandering jet stream and a strong polar vortex over eastern Canada, which sounds familiar. The vortex is forecast to hang around through next week. Add frozen Great Lakes and we could have a very cool spring.

...and we had record cold this morning:

Around daybreak, the temperature at O'Hare International Airport dropped to -22°C, beating the record of -21°C for this date set in 1936. Winds from the northwest at 15-25 km/h made it feel like -30 to -35°C, and a wind chill advisory remained in effect until noon.

The coldest places this morning included -25°C in Aurora, Harvard and Island Lake, -24.4°C in DeKalb and -23.9°C in Mundelein, Union, Waukegan and West Chicago. Wind chills ranged from -33°C in Fox Lake and Wilmette to -36°C in DeKalb.

A brief return to normal this weekend (albeit with some snowfall) will precede another arctic blast next week. When meteorological spring begins on March 1st, we'll still be running 6°C below normal.

This is not helping my Fitbit numbers.

It's also worth noting that, on this day in 1847, rescuers reached the Donner Party. So it could be worse...

Yesterday I found out that Weather Now, my demonstration app, got a mention on local TV in New Hampshire. Apparently it's now in newspapers as well.

Are the mentions driving traffic? Hard to tell. According to Google Analytics, the site had 1,957 unique visitors on Monday against an average of around 400. Yesterday that number fell to 760. But for the three days ending yesterday, 18% of the site's visitors came from New Hampshire and another 23% from Massachusetts and New York. So it is getting picked up.

But is anyone clicking the Donate button? Sadly, no.

(The donate link works for The Daily Parker, too. Hint, hint.)

Local Manchester, N.H., television station WMUR mentioned my weather application on the news last night:

There was only one place in the world colder than Mount Washington this morning: the south pole. The weather website wx now.com says the summit's temperature of 35 degrees below zero early this morning was the second coldest reported temperature on the entire planet.

I can't wait to see the Google analytics.

Oh, joy. Tomorrow night into next week, Chicago could set some cold-weather records for the month of February:

Daytime highs Wednesday and Thursday are predicted to reach no higher than single digits [Fahrenheit] over much of the area–a rare development this late in a cold season. Just how rare?? There have been a grand total of 17 single digit daytime highs beyond Feb. 17 over the past 144 years which averages out to JUST ONE single digit high beyond Feb 17th per decade!

The chill’s not going away anytime soon. Were sub-freezing temps to hold the remaining 11 days of February–something which looks plausible at this distance—Feb 2015 could be in line to add another record to its lineup. Never, in the 144 years of official records here, has a February moved from the 17th to its conclusion having no generated freezing or above daytime highs.

The record low temperature for February is -29°C set 9th February 1899. We're in no danger of breaking that. But 17th February 1903 got down to -24°C, about Thursday night's forecast low.

Can't wait.

After nearly a week walking my ass off in reasonable early-spring weather, I arrived back in Chicago last night to -11°C, which dropped to -15°C for my commute this morning. It is strangely not comforting that it has been this cold this late on only 12 days since 1871. Or that it's going to be even colder Wednesday and Thursday.

Will it warm up? Eventually. But the National Climate Prediction Center forecasts below-average temperatures for the next couple of weeks.

It was really nice to be able to walk 10-14 km every day for a week. Maybe sometime in June I'll be able to do that again.

Getting out of a snowy parking space is tough. Getting into one can be tougher. Boy, do I like my car's all-wheel drive and manual transmission:

I'm actually far enough from the car behind mine that, should he manage to dig himself out fore and aft, he'd have no trouble getting out.

And, wow, has this weather been hell on my Fitbit numbers.

So, I'm sitting here, generally unperturbed by the blizzard yesterday, and it turns out it was the fifth-worst in history:

After further review and the addition of the storm’s last flakes that fell early Monday morning, the final numbers for the historic Super Bowl Blizzard are in. It is interesting to note that this storm fell exactly four years to the days after the city’s 2011 Groundhog Day Blizzard.

The addition snowfall that fell late Sunday and early Monday morning now makes this storm the city’s 5th heaviest snowstorm.

  1. 584 mm January 26-27, 1967 The Big Snow
  2. 585 mm January 1-3, 1999 The New Year’s Storm
  3. 538 mm January 31-February 2, 2011 Groundhog Day Blizzard
  4. 516 mm January 12-14, 1979 Blizzard of 79
  5. 490 mm January 31-February 2, 2015 The Super Bowl Blizzard

Huh. So maybe it was a big storm after all.

My coverage of the 2011 storm is here and here.
