Shockingly hot this afternoon; welcome showers northwest Minnesota

After starting the month of May with record snowfall, we now are looking the first shot of hot air for much of southern and central Minnesota.

An area of showers and isolated thunderstorms was moving across eastern North Dakota and northwest Minnesota this morning. The debris clouds from the dissipating storms will slow the temperature climb somewhat for northern Minnesota.

With the long daylight hours and the warmth of a May sun, the mercury will surge to the lower and middle 90s on increasing southwest winds. A rogue thermometer in south central Minnesota may reach the upper 90s:

A closer look at regional high temperatures today shows the expansive area of very warm afternoon temperatures. Take it easy in the heat of the day.

Please be cautious if you are participating in any activity that puts you in the midday sunshine. You will also be exposed to potential for sunburn.

The heat burst will be short-lived as a cool front slides through Minnesota tonight. Highs on Wednesday will be more comfortable.

Bouts of showers and thunderstorms are in store from Thursday night through the weekend. While the rain may be untimely for your planned events, it will be welcomed by the farmers.

Perhaps this afternoon is a good time to dust off the air conditioning unit!
