Heat advisory issued for much of central, southern Minnesota

The early-season heat wave continues for the next 48-72 hours as temps Sunday and Monday will soar into the upper 90s for much of central and southern Minnesota. 

With that, the National Weather Service has issued a heat advisory for a large area of the state, warning that dangerous heat indexes of nearly 100 degrees will exist both Sunday and Memorial Day. 

The NWS says it issued the heat advisory for three reasons: 

1. It's the first heat wave of the season. 
2. It's happening during a peak time for outdoor activities. 
3. Winds will be light, therefore providing little cooling relief.

Temps will remain in the 90s for much of southern Minnesota through Tuesday before cooling into the mid-80s Wednesday and Thursday. 

Strong storms possible Monday Tuesday

There could be some severe storms in northern and central Minnesota on Monday, with risks for large hail and damaging winds. 

NOAA's Storm Prediction Center has almost all of Minnesota under a marginal risk for severe storms both Monday and Tuesday, which is similar to what was in place when strong winds produced damage along a path from near Glencoe through the southern suburbs a few days ago. 

Northern Minnesota could see some severe weather Sunday night if storms are able to develop, the NWS office in Grand Forks says.
