The National Weather Service says a Heat advisory will be in effect from Noon until 8 pm Thursday. Highs in the low 90s with dew points in the low to mid-70s will produce heat indices around 100 degrees Thursday afternoon.

A Heat Advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids...stay in an air-conditioned room...stay out of the sun...and check up on relatives and neighbors.

Thunderstorms will slowly diminish this morning from east central MN into northwest WI. The main threat this morning will be from heavy rainfall from Mille Lacs Lake down toward Siren, WI.

Thunderstorms are expected to develop again this afternoon from west central MN, through the Twin Cities into west central WI. There is a slight risk of severe weather with this activity, with damaging winds being the main threat. Thunderstorms are
expected to slowly drift south tonight toward southern MN. All activity today and tonight will be capable of producing torrential rainfall and localized flooding.

Once again, afternoon heat indices are expected to top out around 100 degrees along and south of a line from New Ulm, to the Twin Cities and Chippewa Falls, WI.

Friday through Wednesday Chances for Thunderstorms will continue through Sunday night. The threat for severe weather is low, but a continued risk for excessive rainfall will exist for south central MN through Friday
