Cassie and I spent almost all day outside yesterday, starting at Puptown:

Including pool time and some new friends:

Followed by a 3½-kilometer walk to Spiteful Brewing, where one of us read a book and the other napped:

Today, though she doesn't know it yet, she will get a bath.
It was 30.5°C at 6:09pm and 21.1°C at 7:10pm. At this writing, it's 18.3°C, with thunderstorms approaching from the west. They should hit late tonight. I'm still keeping my windows open.

It's mid-July today, at least until around 8pm, when late April should return. The Tribune reported this morning that our spring has had nearly three times the rain as last spring, but actually hasn't gotten much wetter than normal.
Meanwhile:
Finally, via The Onion, Google Maps now shows you shortcuts through people's houses when they're not home.
This week's temperatures tell a story of incoherence and frustration: Monday, 26°C; Tuesday, 16°C; yesterday, 14°C; today (so far), 27°C. And this is after a record high of 33°C just a week ago—and a low just above 10°C Tuesday morning.

So while I'm wearing out the tracks on my window sashes, I'll have these items to read while my house either cools down or warms up:
And finally, Ian Bogost feels elated that cryptocurrencies have crashed, particularly because he doesn't own any.
At 7am Monday, it was 12°C at Inner Drive Technology World Headquarters. By 6pm the temperature had gone up to 26.5°C, then 29.8°C at 2pm Tuesday, then 29.1°C at 3:15pm yesterday, before a cold front finally ploughed through and got us down to lovely sleeping weather right before I turned in:

The slow rise in my indoor temperature from 7am to 5pm was just my normal A/C program, as was the decline when the A/C turned on at 5. Then at 6, I discovered that the cold front had gone through, so I opened the windows.
Overnight, though, this happened:

This did not lead to a restful sleep, but did apparently lead to a backache.
I'm going to leave my windows open out of optimism that the forecast is accurate and today's high will only hit 27°C. But if it's above 25°C at 6pm, I'm giving up and turning on the A/C. I need sleep.
Such is the end of spring in Chicago.
Update, 3:15pm: I tried, man. But after sweating through two meetings and watching Cassie move from the couch to the hardwood flor, I gave up and turned on the AC. Now it's 31.5°C outside and a dry 24.4°C inside:

Sheesh:
And finally, when I left for San Francisco on Saturday morning, it was 10°C and sunny. Here we are about 76 hours later and it's 30°C. We really don't have spring or fall here some years.
Chicago actually had clear skies and lovely spring weather today. That said, I'm in San Francisco this weekend, where the weather is almost exactly the same (12°C and clear).
Posting will be sporadic until Tuesday.
Gray skies, day 45: they say the sun will come out tomorrow. I would not bet my bottom dollar on that.
In any event, I'll be in San Francisco for a couple of days, where they've had sun on and off for a while, with sun predicted tomorrow and Sunday. Then, if the predictions hold true, I'll come back here Monday in time to throw open all my windows.
We'll see. But I am really sick of the rain and clouds already.
I mentioned a couple days ago that we haven't seen the sun much this spring. Today the sun came out for only the second time in the last 43 days:
The National Weather Service categorized just one day in April as “clear and sunny,” said Kevin Donofrio, science and operations officer. NBC 5 meteorologist Paul Deanno said Tuesday just one of the past 42 days saw significant sunshine. That report was followed by another dark and soggy day.
Donofrio said this April saw 39.6 mm more rain than usual. Paul Walker, senior metrologist with AccuWeather, said there were only six days without rain last month.
Chicago was also 1.5°C cooler than an average April, Walker said. Last year, it was 1.2°C warmer.
The gloom covered all of Illinois, in fact:
It’s not a stretch to say that most in Illinois are ready for warm weather by the time we hit mid-April. However, this year did not deliver as April temperatures were persistently well below normal. ... [M]ost days this past month were 3°C to 6°C colder than normal. Only 8 out of 30 April days in Galesburg were warmer than normal, and most by only a few degrees.
As a result of the colder weather, most of the state experienced below freezing temperatures as late as mid-April, and frost was reported as far south as the St. Louis Metro East on April 26.
Given how persistently rainy last month was, we best have a plethora of May flowers. For most places, the total amount of April precipitation was not excessive, and some areas were drier than normal. However, precipitation frequency last month was unusually high as most places recorded 12+ days with some measurable precipitation. Macomb had 22 days with measurable precipitation last month, Aurora had 20, Champaign had 19, and Cairo had 18. The 22 wet days in Macomb last month set a new record for April, which was the 2nd highest frequency of any month on record, only less than the 23 wet days in Macomb in October 2009. Frequent, small precipitation meant most places only had 2 to 2.5 days between precipitation events last month, which stymied fieldwork statewide.
Fortunately, the forecast calls for warmer and sunnier weather next week, with sun and 29°C forecast for Tuesday.
Last month we had the second-gloomiest April on record, with only 34% of possible sunshine reaching Chicago all month. Normal is 51%.
I realize May is only 34 hours old, but we haven't gotten any sunshine this month, either, with rain forecast tonight, Tuesday night, and Thursday. Then I'm heading to San Francisco for the weekend, where they haven't had any clouds in a while. I could use the sunshine.
