After almost 6 straight days of record breaking high temperatures, the weather will go from May to February once again. A deep area of low pressure will track across the plains and move into northeast Iowa by Friday.
With a couple rounds of storms and rain, totals through Friday could add up to closer to 2" in northeastern Illinois and along the Wisconsin border. Thursday's rain could bring about one inch, and then we could add another inch by Friday afternoon.
By Friday evening the low pressure system will be situated northeast of the area, but will pull in colder air by Saturday. This will allow for a transition to a rain/snow mix to then lighter snow by Saturday morning. Right now, accumulations don't look to be high, but we'll keep you posted as we get closer. Nonetheless, it will be a shock to the system by Saturday!
