A pattern change is on the way and it all started with the thunderstorms we saw this morning. A cold front with an area of low pressure north of Wisconsin this morning combined with strong low level winds helped fire off a few storms early on. Those have sinced moved across the other side of Lake Michigan as an area of low pressure has quickly pushed that front back north as a warm front. Temperatures as of 10 am are already approaching close to 60° in some locations! As this next low moves closer to northeast Iowa, strong winds aloft will continue to pump in modified gulf air. This will combine with another cold front (a stronger cold front) that will move through during the afternoon/early evening. As it does we can't rule out the development of a few more storms by dinner time. The latest outlook from the
Storm Prediction Center has highlighted much of the Stateline in a slight risk for severe weather with the greatest threat being gusty winds. The stronger winds above will help create gusty winds at the surface today and tonight.
As the cold front moves through temperatures will drop by daybreak Tuesday with lows in the middle and upper 20s and we'll only rise into the upper 30s by the afternoon.
Great discussion and graphics! Thanks!
ReplyDeleteI'm currently located on the back side of that cold front and let me tell you it is CHILLY!! Worst of all the air is very moist, which makes it feel even colder. YUCK! Watch out....it's coming your way!

ReplyDeleteThanks for the update on where you are. It's amazing looking at the temperature analysis and noting the large contrast from the Great Lakes into the Plains! Once that front comes through tonight it's going to feel a lot different by tomorrow. Hard to believe we're at 62° in Rockford (11am) and Des Moines they're in the 30s.
