Wednesday will bring another hot and humid day with triple digit heat index values across southern Minnesota. Temperatures start to cool Thursday into the weekend.

The Twin Cities broke a 52-year old record Tuesday afternoon with a high of 98 degrees. The previous record was 97 set in 1971. A few places in western Minnesota reached the triple digits. The hot spot was Canby with a high of 103. Marshall hit 102.

The rest of southern Minnesota saw highs in the mid to upper 90s. Crystal and Eden Prairie were the hot spots within the Twin Cities metro area, topping out at 99 degrees.

The dew points were also incredibly high and the highest of our summer season.

The dew point topped out at a whopping 79 in the Twin Cities, just 3 degrees from the all-time record high dew point of 82 set in 2011. It was only our third time this season with dew points in the 70s as the drought has kept things less humid overall than normal.

Those temperatures and dew points combined to create heat index values above 110 degrees. The Twin Cities saw peak heat indices of between 114 and 118 degrees late Tuesday afternoon.

Brace for another hot day Wednesday. An excessive heat warning continues into late Wednesday evening across southern Minnesota. A heat advisory is posted for Thursday for slightly less hot conditions.

The combination of heat and humidity will again make for triple-digit heat indices, although not as high as Tuesday. Both dew points and temperatures will be slightly lower.

The warmest temperatures will be in far southern Minnesota where highs will top out in the upper 90s.

Like Tuesday, there will be a substantial temperature difference from south to north with northern Minnesota seeing a mix of fog, clouds and highs in the 70s.

A disturbance could touch off a few showers overnight Wednesday night across northern Minnesota and there’s a statewide chance of a few isolated showers or thunderstorms Friday, but overall significant and widespread rainfall is not expecting in the coming days.

We will see cooler temperatures by the weekend however. Highs will be in the 70s to low 80s Saturday and Sunday.
