I wonder if that strange small area where it's like 25 degrees cooler than everything else is just a glitch, or something more sinister and spooky. I guess when it updates in appx. 20 minutes I'll....have a new picture to look at.
Well, at least you've finally found that horrible Midwest winter everybody warned you about.
I once actually experienced something like this in the opposite direction...hot instead of cold.
5am, driving through Omaha, and the temperature went from the 60's to over 100 for maybe an hour, then dropped back.
The apparent technical term (according to 1110 KFAB...Nebraska's SUPERSTATION!): "Hot Flash". It was caused by precipitation hitting hot air and forcing it to the ground in the process. The precipitation evaporated in the hot air, so it didn't rain. It was apparently localized to the Omaha area.
It was easily the weirdest oddball weather experience I've ever had.
Sudden changes like that do happen, but in places that are next to mountains. It's due to the chinook winds.
Like Spearfish, South Dakota:
Spearfish holds the world record for the fastest temperature change, which ocurred on January 23, 1943. On that day, the weather station recorded a jump from -4F(-20C) to 45F(7C) in two minutes. An hour and a half later, the same weather station measured a decrease from 54F(12C) to -4F(-20C) in only 27 minutes (Parker, 1981).
