Portions of Minnesota are seeing storms with very heavy rain Monday morning. By afternoon, heat and humidity will be the concern, with a heat index near 100 in southern Minnesota.
A wide area of showers and storms built up over southern Minnesota early Monday, bringing persistent thunderstorms with heavy rain to areas from the Twin Cities through the Minnesota River Valley. This satellite image shows that convection from around 2 a.m. Monday:
Because many areas under this weather complex have already seen 2 to 3 inches of rain or more as of Monday morning, a flash flood watch is in effect until 10 a.m.
The persistent area of rain is finally starting to move east as of 7 a.m., but another band of storms is moving in behind this in west-central Minnesota.
The widespread showers and storms continue to move out and diminish through the morning, then the afternoon stays dry for most of the state, with only isolated storms possible.
As the storms move out, the heat intensifies. Much of western and southern Minnesota could make it to 90 or above.
With very humid weather across the state, the heat indices will be high and could hit 100, especially in southern parts of the state.
