I hope the GFS and its AI counterpart is deleted. It simply shouldn't exist. Winters would be quite a bit less emotional as well.

And now .40" in 25 minutes in Aurora: https://www.weather.gov/wrh/timeseries?site=KUAO

Really interesting page from LOT for the 50th anniversary of the F4 tornado in northeast IL. I never knew about the other exceptional aspects of this storm. For instance, it hailed for 60-90 minutes straight in some areas! Overview During the evening hours of June 13, 1976, a few isolated storms developed in northeastern Illinois near the Chicago Metropolitan Area. One of those storms developed into a slow-moving, supercell thunderstorm. This storm produced a tornado starting near Lemont which followed an unusual winding path over the hour to near Darien and Downers Grove. This tornado caused 2 fatalities, 23 injuries, and approximately $13 million ($76 million in 2025) in damages. In addition to the tornado, the slow movement of the storm caused a significant flash flood event in far southeastern DuPage County and central Cook County. Over 1 hour of nearly continuous hail occurred on the southwest side of Chicago. Much more here if you're interested, including photos: https://www.weather.gov/lot/1976_06_13_tornado

Anything involving the GFS, period. The 12z deterministic GFS had 75°F for a high here today. Ended up with 85°F instead. Garbage in, garbage out.
