Look (and listen) for a few scattered areas of much needed rainfall into early Tuesday morning. A line of storms moving slowly northeast is packing lightning, thunder, heavy downpours, gusty winds and some hail.
A warm front is pushing through southern Minnesota overnight and will trigger scattered showers and a few boomers into Tuesday morning. Most areas will see only a quarter to half inch of rain or so, but some lucky spots may see up to an inch or more.
After the front sails through Tuesday, warm southerly breezes will boost temperatures in the afternoon. Upper 70s will be common, and some spots in southern Minnesota could see the season's first 80 degree reading.
I would not be shocked to see temperatures pushing near 80 as far north as the metro by late Tuesday afternoon.
