GO BIG OR GO HOME...
It was another "scorcher here in the Midwest with many locations hitting the BIG 7-0. Multiple records fell across the region and Moline even busted the all-time February high, reaching 74 degrees.
Here are the records from my local area:
Many readings were 35 degrees above normal across eastern Iowa. If this were mid-July, when the average temperature is 85 degrees, and temperatures were 35 degrees above normal..... that'd be a 120 degree day!

Now moisture is on the move though, and showers and thunderstorms will be possible Monday afternoon. Here's the surface pattern on the GFS late on Monday.:
The surface low is way up in Canada and that will pump in plenty of warm air and moisture. Check out these dew points - almost to 60 degrees! Incredibly rare in February:
