The Daily Parker

Blowing off the last game of the season I bought tickets for did not come easily. I struggled with the decision for most of the afternoon. I needn't have:

The temperature at Midway has flattened out at 13°C as a thunderstorm has started passing overhead.

Oh, and après le déluge, the Cubs can resume in the top of the 4th with the last-place Pirates beating them 3-0.

So, you know, I think I made the right choice.

I did three touristy things today: first, a stop at Westminster Palace for the official tour, during which I got to stand right in the Government benches in the House of Commons, less than a meter from where the P.M. sits when they're in session. No photographs allowed, I'm afraid; but now the whole setup makes a lot more sense to me. I'm all set for the resumption of Question Time, the comedy half-hour broadcast every Wednesday from the chamber.

Second, a direct boat trip down the Thames to Greenwich, with some wanderings through the Royal Observatory:

Finally, a trip out to Southend-on-Sea to see the sea. And, apparently, to get rained on; here's the storm blowing in:

In all, a very fun day with lots of walking. (I'll eventually put my Google Earth tracks up.)

Tomorrow: Cambridge.

They put this out for us every single day:

And this is what happens when it's 29°C in Trafalgar Square:

And, finally, my temporary Summer Office, the Dickens Inn at St. Katharine's Wharf:

All right. Back to work.

The National Oceanic and Atmospheric Administration has published its climate highlights for July 2009:

• An abnormally strong, persistent upper-level pattern produced more than 400 record low minimum temperatures and 1,300 record low maximum temperatures (lowest high temperature) across the nine-state area that make up the Central region.
• Ohio, Iowa, Illinois, Indiana, West Virginia, and Pennsylvania experienced their coolest July on record. Kentucky, Missouri, Wisconsin, and Michigan each had their second coolest July on record, while Minnesota and Tennessee had their third coolest July on record.

And they have art:

First, on the 45th anniversary of President Johnson signing the Voting Rights Act into law, Sonia Sotomayor was confirmed an Associate Justice of the United States Supreme Court.

Second, John Hughes died this afternoon. He was 59.

Third, Britain has had unusually squishy summer, which only matters because I'm spending the entire last half of August there. Oh, it also matters to anyone trying to fly out of the U.K.

Usually I hate July weather in Chicago. Not this year. We ended up with the coolest July in my lifetime (at Midway), and also one of the driest, making for an unusually pleasant month:

Chicago's 69.4-degree average July temperature at O'Hare International Airport was the coolest of the past 17 years. But at Midway Airport, the month's 71-degree average temperature was the site's coolest in 42 years. Estimates based on the month's temperatures suggest the need for air conditioning was 30 percent below the long-term average.

The month's lack of rainfall was impressive -- and a huge change from the wet spring that kept farmers out of their fields. Only 1.53 inches of rain was measured here in July, less than half the 3.51 inches considered normal.

One symptom of this: O'Hare recorded only one day in which the temperature hit 30°C, and Midway only two, while here at Inner Drive Technology Worldwide Headquarters the lake's proximity kept it even cooler than that.

But this doesn't mean it was ever cold, either. Just pleasant. I sure will miss it this week: the forecast calls for warmer, wetter weather until the middle of the month.

Pilots will tell you they'd rather be down here wishing they were up there than up there wishing they were down here. (See also, "All takeoffs are optional; all landings are mandatory.") Most of the time it's an easy choice for private pilots whether to go for a flight, especially in Chicago where the weather, not to put too fine a point on it, often sucks.

Today, I had scheduled a flight, but I decided to stay on the ground after thinking really hard about it. Right now Chicago Executive reports scattered clouds at 3600 ft and a medium (9 kt) breeze; nothing I can't handle. However, the forecast calls for gusts to increase to 18 kt, thickening clouds, and the possibility of thunderstorms this afternoon.

Today's mission, though, was simply to fly up to Waukegan or Kenosha, shoot some landings, and return. Today's weather forecast ordinarily wouldn't stop the flight, because as the weather deteriorates, I only have to fly 15 minutes and be home. Not to mention, I'll never be more than 6 minutes from an airport, as the whole point of the flight is to practice landings.

So why stay on the ground? Because I decided I didn't meet the IM-SAFE checklist. Here's how it went: Illness, no; Medication that causes physical impairment, no; Stress, hmmm; Alcohol, no (nor its effects—the FAA considers "under the influence" to include a hangover, even with a zero blood-alcohol content); Fatigue, hmmm again; Emotion: not an issue.

See, today, I'm thinking about the stack of reading materials for Duke on top of a lot of client work due this week, and even though I got a good night's sleep, I feel like I could have gotten more. Am I safe to fly around the airport and practice landings feeling like this? Yes, I believe I would be—if the weather were perfect. But the winds and clouds are going to increase while I'm getting fatigued from all those landings, which means each landing will be much harder than the last one. That means I probably won't learn from them, I'll probably start to get frustrated, and then by the time I return to Chicago Executive I'll be cranky, tired, and fighting gusty crosswinds while trying to get an aluminum tube to fall 500 m out of the sky so gently that someone can use it again. Not to mention, it's an hour-long drive each way, two hours in which I could be writing for clients or reading for school.

So it's a very tough call, and I'd really like be up there today. Just not enough to risk wasting the trip.

Usually, my July visits to my family in San Francisco allow me to get away from Chicago's oppressive heat. This year, both cities are about the same, San Francisco just a little warmer than usual, and Chicago...well, it's the coolest July of my life:

July has slipped to the coolest to date here in 42 years—its 68.7°F degree average temperature running nearly 5 degrees behind the long-term (138-year) average. Friday's 70°F high was the first time in 53 years a July 17 temperature failed to rise above 70—you'd have to travel back to a 64°F high 85 years ago to find a July 17 that was cooler.

The average high for July's first 17 days has been 77.5°F—the second coolest in the 50 years of O'Hare Airport weather records dating back to 1959. Only 1967's 76.2°F tally has been cooler.

Maybe Chicago will have a super-hot August this year. Like, when I'm in London....

Chicago had its coolest July 8th in more than a century yesterday, capping the coolest summer (to date) in decades:

For the 12th time this meteorological summer (since June 1), daytime highs failed to reach 70°F Wednesday. Only one other year in the past half century has hosted so many sub-70-degree days up to this point in a summer season -- 1969, when 14 such days occurred.

Wednesday's paltry 65°F high at O'Hare International Airport (an early-May-level temperature and a reading 18°F degrees below normal) was also the city's coolest July 8 high in 118 years -- since a 61°F-degree high on the date in 1891.

The flipside, of course, is that the weather is delightful. Unfortunately the forecast for this week calls for much warmer (i.e., seasonal) temperatures. Pity.

It's time for the semi-annual update of the Chicago sunrise chart. (You can get one for your own location at http://www.wx-now.com/Sunrise/SunriseChart.aspx.)
