We'll remain on the 'cooler side' of storm systems this week with low pressure over the East Coast blocking warmth from making it into the Great Lakes.
Low pressure moving out of the Plains Monday evening will be the focus for thunderstorms over Minnesota and northern Iowa through the evening. A few stronger thunderstorms closer tied to the low are possible. Isolated showers will develop further east over Wisconsin and
Illinois as a warm front moves closer. The warm front falls just short of passing the Stateline, but will become the focus Monday night for the development of showers and thunderstorms.
The amount of moisture in the atmosphere will increase with the arrival of the low and this could lead to bouts of heavier rainfall during the overnight. Rain totals won't be uniform throughout the Stateline, and we'll likely see a wide range of amounts by Tuesday morning. Areas most likely to see the highest rain totals will be from Janesville down to Rockford and to the east. Rainfall totals could add up to over an inch with repeated rounds through Tuesday morning. Further west rain totals would be drastically lower.
