That's the code for "frontal passage" on aviation meteorological reports. Apparently yesterday while I was on my way to O'Hare I missed a big one:

While temperatures began dropping across the far northern suburbs as early as mid-afternoon, the city was invaded by 30+ mph gusts late in the evening rush hour, initiating a thermal tailspin. In a single hour's time, readings at the Harrison-Dever Crib, three miles off Chicago's shoreline, dove from 62°F to 42°F—a 20°F pullback—between 6 and 7 p.m. The same period saw readings at Northerly Island on the city's lakefront plunge from 64°F to 47°F. A minute-by-minute temperature analysis off a Weather Bug sensor on the South Side at the Dumas Elementary School indicated readings there plunged 15°F in only 12 minutes—from 62°F at 6:39 p.m. to 47°F at 6:51. By late evening, North Shore readings were uniformly up to 25°F off the 60°F levels of only hours before.

Yikes. Here's the art:

Today's forecast is for sunny skies and 26°C.

Oh, sorry. That's my forecast. Back in Chicago they've got snow and freezing temperatures. Sorry.

A friend and I toured the Big Boss Brewing Co. in Raleigh yesterday. Possibly owing to the gorgeous weather, or a widespread spirit of scientific inquiry, or—long shot here—the $1 33 cL beer samples, yesterday's tour seemed awfully popular:

A winter storm off the coast of North Carolina has brought snow to both Chicago and Raleigh:

25 mm of snow had fallen at O'Hare by 8:30 p.m. Wednesday, with snow still coming down hard. That was enough to push the city's official seasonal snow tally above 127 cm for the third consecutive year. There's been only one other string of three consecutive 50+ inch seasons in 125 years of snow measurements here and it occurred between 1976 to 1979.

In North Carolina the snow is causing the same kinds of disruptions as in Chicago—slow traffic, nervous parents, confused dogs—but...well, it's not quite as much snow:

I'm splitting my time between Chicago and Raleigh lately, and it looks like I'll continue to do so for quite a while. This causes one minor inconvenience: my car doesn't fit in the overhead compartment on a CRJ. (For that matter, an anorexic gerbil won't fit in the overhead compartment on one of those things, but that's another issue.)

Chicago, however, is a major city with an extensive public transportation system (no snickering from natives, please). Chicago also has Zipcars, a by-the-hour car-rental cooperative, with six cars stationed less than four blocks from my house. Four blocks—800 m—seems to suburbanites like a very long walk to get a car, but actually, I'm lucky if I get to park my own car that close most days. So this is an improvement.

iGo, which costs a little less and works in partnership with the CTA, is another option. Unfortunately they don't have any cars within 1500 m of my house. Walking around the block to get the Zipcar suddenly seems more attractive. Walking eight blocks to get a car is less so.

Zipcars also has the advantage of national reach. Given how often I travel (especially to San Francisco), this has tremendous appeal.

Now if only Chicago had a puppy-rental service for those times when I miss Parker...

After waking up at 4:30 for two mornings in a row, I really would like my body to figure out what time zone it's in. Maybe the problem is the Indian half-hour (it's 11½ hours ahead of Chicago, not 11, not 12), or possibly it was the two overnight flights in a row? Maybe I should just be glad I've had a relatively easy time getting to a point where I go to sleep at night (last night around 9:30pm) and wake up in the morning, instead of the reverse.

Meanwhile, back in Raleigh, it looks like they have some weather this weekend:

Tonight: Snow likely before midnight, then snow and sleet. Low around -4°C. East wind between 13 and 21 km/h, with gusts as high as 40 km/h. Chance of precipitation is 100%. Total nighttime snow and sleet accumulation of 8–12 cm possible.

Saturday: Snow and sleet before 1pm, then freezing rain and sleet. High near -4°C. Northeast wind around 24 km/h, with gusts as high as 47 km/h. Chance of precipitation is 100%. New ice accumulation of less than a 1 mm possible. New snow and sleet accumulation of 8–12 cm possible.

Friends have reported stockpiling mac and cheese and wine. In some respects, I wish I were there. In others...well, it's going to be 20°C and foggy in Delhi today, while we Dukies go out to the Red Fort and Old Delhi.

More, with photos (I hope), tonight.
