Extreme weather, early-summer edition

Last night we delayed the start of Terra Nostra fifteen minutes because a supercell thunderstorm decided to pass through:

The severe supercell thunderstorm that tore through Chicagoland Monday night toppled planes, ripped the roof off at least one apartment building, dropped hail as large as 1.5 inches in diameter and left tens of thousands without power in its wake.

In Cook County, 84 mph winds gusted at O’Hare International Airport. That was strong enough to turn over numerous planes at Schaumburg Regional Airport around 6:25 p.m.

Near Elk Grove Village around 6:30 p.m., roofing material started flying off an industrial building. The entire roof of a three-story apartment building was ripped off near Maywood around 6:50 p.m.

The system reached the Lake Michigan shoreline near downtown Chicago around 6:45 p.m., with “several tree branches downed just northwest of Montrose Harbor,” the weather service reported. Wind speeds of 64 knots were reported a few miles from Navy Pier and a buoy station near Calumet Harbor clocked wind speeds of 54 mph.

The weather report from O'Hare at 6:44pm gives you some indication of what we had in downtown Chicago half an hour later.

Today, the warm front that provided the energy driving that storm has already pushed temperatures over 30°C with a likely high of 36°C:

And wow, it's sticky, with dewpoints near 24°C and heat indices above 38°C. Can't wait for my commute home...
