Few Showers to Start the Week, Storms by the Middle of the Week

We've had some pretty decent rainfall over the past couple of weeks and depending on where you live in Northern Illinois, it's almost been too much.  Unfortunately that hasn't quite been the case for Rockford.  Yes, we had some very heavy rainfall last week but we're still running over an inch under where we need to be!  However, ask anyone to the south and they'll likely tell you they've received way too much.

The recent warm spells do pull a lot of moisture out of the ground so that's how we're quickly able to dry up following the heavy rainfall.

Sunday night will be dry, but a few showers will dot the skies for the first half of Monday ahead of a cold front.  Higher chance for thunderstorms may stay just to our south as the cold front will be south of Rochelle during peak heating of the afternoon.

That front will pull back north as a warm front late Tuesday into Wednesday morning.  As it does a fairly moisture rich air mass will follow the front leading to heavy rainfall over the Midwest, and possibly over Northern Illinois and Southern Wisconsin.

Along with the possibility of heavy rainfall, there will also be the threat for strong to severe thunderstorms Wednesday afternoon.  It's a little too early to pinpoint exactly where those storms could develop, but a very warm and unstable air mass will be located just south of the warm front.  Wherever that front ends up will help determine where the stronger thunderstorms will be.
