Air-Road Blog: Chicago

chicago080111.jpg

We flew to Chicago yesterday. It was clear and warm as we left Oakland. We landed in Salt Lake City just as a big monsoon-driven cell passed over the area. And in Chicago, we emerged into a steam bath. It was about nearly 1 in the morning and about 80 degrees. My first impression was 80 sopping-wet degrees, but I think you get used to it. I say “I think” because like millions of others in Chicagoland, I’m living Monday morning in air-conditioned comfort as the temperature outside climbs toward the 90s (and there’s a complicating factor today: the National Weather Service has issued an air-quality alert for high pollution levels today).

In other weather talk: A neighbor mentioned she’d heard that Chicago had had more than 6 inches of rain in a day recently, but thought that might have been a typo. Well, no, it wasn’t. As the Chicago Weather Center site reports in detail, July 2011 was one of the driest Chicago Julys on record–until 10 days ago. Then storms began rolling in, including one that dropped 6.86 inches on July 23 (the most on one date in the city going back to 1870), and the month turned into the city’s rainiest July on record). Here’s the rundown from WGN’s Tom Skilling and company:

From one of driest to all-time wettest July in just six days

Wettest July also third-warmest

Chicago’s 24-hour rainfall record …

(And the picture? That’s Lunt Avenue, in front of my sister’s place in West Rogers Park. God’s Battle Axe? Well, it gets your attention. The church describes itself as “a fast growing charismatic prayer ministry … destroying the works of darkness thereby impacting the world.” The ministry’s leader “is referred to by some of his close friends as ‘a Praying Machine: The Anointed Apostle of Prayers.’ “)

Journal of Rain-Driving Photography

A picture made during our storm a couple days ago.

Side conversation: Is this picture illegal? Or maybe just unwise? California has laws against using cellphones while driving (unless you have a hands-free setup) and texting while driving (I never believed that people tried to text and drive until I saw them in action on adjacent freeway lanes. Amazing). But a non-exhaustive search of the state vehicle code (there are only so many hours in the day) does not turn up an outright prohibition on drivers using cameras and taking pictures while driving (the Department of Motor Vehicles admonishes us to avoid distractions, such as eating, doing personal grooming, reading the newspaper, working on Rubik’s cubes, etc., while we’re behind the wheel).

Road Blog: Chicago

Today, the road trip included zero time on the road. My sister and I did walk a few blocks up the street and back, though. And Eamon and Sakura arrived after their detour from Council Bluffs to Lamoni, Iowa, and Independence, Missouri. Their drive today brought them from Independence, Harry S Truman's hometown, through 100-degree temperatures in Missouri and severe thunderstorms near Bloomington, Illinois–family home of Adlai Stevenson, who failed to succeed Truman.

Thunderstorms passed through the Chicago area, too. It's an unusual enough occurrence for me, living in the mostly thunder-free Bay Area, that I went out into Ann and Dan's backyard and recorded some of the storm as it passed. The storm and recording were less than Wagnerian in its dramatic dimension, but was plenty atmospheric. Here's an MP3 snippet:

Chicagostorm060411

Back on the other end of this trip, the endless rainy season of 2010-11 continues in the Bay Area and Northern California. To define "endless rainy season," we refer to the National Weather Service record report from earlier today, which runs down a few locations that saw their rainiest June 4th ever. An earlier forecast discussion raised the possibility that some locations might exceed their monthly records for the entire month of June today (a surprising possibility, but not an amazing one: we don't get a lot of rain on average in June; the June record for San Francisco, recorded in 1884, is about two and a half inches. One earlier report ran down rainfall totals over the region through late Saturday morning. Noteworthy: the 2-inch-plus totals in the Santa Cruz Mountains and the 3-inch plus amounts in the Santa Lucia Range in Monterey County.

It's more than I want to get into in detail at this late hour, but: water. One impression driving across the northern Rockies and Plains is how wet and green everything looks (but no, we didn't see any honest-to-goodness flooding in Montana or South Dakota) In California, you think of water supply when you see all the rain (and in the mountains, snow) we've been getting as the wet season continues. The state's daily report on its largest reservoirs shows storage is more than 110 percent of average for this date and the biggest lakes are close to capacity. In the mountains, the snowpack is still at 97 percent of its April 1 average–April 1 being the date when the snowpack is at its maximum. We're two months past that now, and the snowpack is at 343 percent of normal for the beginning of June (in a regional breakdown, the snowpack for the Northern Sierra and far northern mountains is at 559 percent of normal for this date (see California Department of Water Resources/California Data Exchange Center: Snow Water Equivalents).

Day Trip

road152511a.jpg

I took yesterday off. So did Kate. We did a mini-road trip to Mendocino County with The Dog. Though it’s late May, and we like to think we ought to be well into the dry season, it rained on the way north and then sporadically all day. Beautiful, though. And we were home by dark.

Above: That’s looking “southbound” (actual direction may be east) on Highway 128, along what I think of as the “true summit” area just north of the Sonoma-Mendocino county line. Heading north, you climb a grade of about two miles or so and are briefly rewarded with the impression that you’ve reached the top as you head down a little descent. Then the road pitches up sharply again before you cross a higher crest and start downhill toward Mountain House Road, which connects to Hopland. This Interesting aspect for me of driving roads in this area is that I’ve ridden them in all sorts of conditions, dry, wet, in the middle of the night. The constant: I’m usually pretty tired, because this stretch of Highway is located deep into some long brevet routes I’ve done–better than 100 miles into most, more than 200 miles into a couple of them.

Below: mini-slideshow of scenes from the highway.

Midnight Rain

Up late tonight–not unusual–reading up on what’s supposed to happen with the first stage of the Tour of California in the morning. The race is starting at Lake Tahoe to give it some true alpine flavor. You know, like that big race they have in France every summer (and also, the big races in Italy, Spain, and elsewhere, not to leave anyone out). No one could have guessed when the route was chosen last year that a winter-ish storm would roll into the state this weekend. But it did. I’m listening to rain down here at sea level and looking at weather reports of snow up along Interstate 80 clear over Donner Summit to Lake Tahoe. So now, the race organizers say they’ll wait until 9 a.m. to decide whether the race will proceed on a mountainous circuit around the lake or be abbreviated to avoid sending 168 racers sliding around a potentially snowy, icy course. We’ll see.

Tax Night Drizzle

drizzle041811.jpg

Just came in from The Dog’s nightly patrol. It’s been drizzling since late afternoon. I wondered what kind of picture you might get if you pointed a light–in this case, an LED headlight–up into the rain with the shutter open for 10 seconds. This is the answer. The orange hue suffusing everything is from the city lights; the blueish filaments are the drizzle coming down. I once saw a monster “flashlight” in a Restoration Hardware catalogue; it was actually a portable, battery-powered spotlight that you could probably use in an operating theater (although I think it could run on maximum power for only 20 minutes or so). I’ve fantasized about having one of those lights as an attention-getter. To light up some driver blowing through a stop sign at night, say. But I’d like to try the drizzle experiment with one, too.

Birthday Weekend: (April) Fool on the Trail

Bigsprings20110401

Friday, April Fool’s Day: Day 1 of Birthday weekend, on Big Springs Trail in Tilden Regional Park, high above Berkeley’s urban jungle. The advertised weather for the day had been for a bit of a cool-off after several days of increasingly warm and beautiful days that led to record temperatures in many locations on Thursday. But when The Dog and I hit the trail, the day was warm-plus; not oppressive, but hot in the full sun. The hills are at their best right now: green, grasses profuse, lots of wildflowers, water seeping from hillside springs due to recent heavy rains (as a media type, I know it’ll be a matter of days or a week or two until someone says that this summer/fall fire season could be particularly intense because of the thick spring foliage).

Then It Stopped

curb032311a.jpg

This was around the corner, on California Street, late last Wednesday morning. The pre-work routine wraps up with The Dog and I perambulating the neighborhood before I head off across the Bay. Last week was wet, maybe the wettest week of the wet season. Jan Null, a local meteorologist who I like to say wrote the book on San Francisco rain (it was his doctoral dissertation), has developed his own scale for storm intensity–it takes into account factors like the amount of rain and duration of high winds–and he rated the one that came through on Thursday as the strongest of the season.

Then Sunday, all that seemed to stop. It had been dry from midday Saturday, dry enough to go out and mow the lawn before it became unmowable and try to drain the water that had pooled in the crawl space. It drizzled a little tonight, but the weather forecast for the week is dry and warm, up to the 70s by Thursday. I think all the vegetation here is going to explode.
