A severe weather risk returns Monday

The humidity is back as temperatures nudge even higher

Humid air pushes across Minnesota Monday, adding to the storm risk and making the already high temperatures feel even warmer.

Monday’s forecast

A southerly wind flow started moving more humid air into the state overnight. Northern Minnesota, where dew points are still in the 40s and 50s as of Monday morning, is starting the day with most lows in the 50s. Southern Minnesota is already more humid, and that helped keep overnight temperatures much higher, in the 60s and 70s with muggier conditions.

The higher dew points spread north through the day, and all of Minnesota is likely to see dew points in the 60s by the afternoon. Highs will be in the 80s north and low 90s south, which is already a couple degrees warmer for most spots versus Sunday.

The increasing humidity will also make it feel even warmer.

The instability has also increased again, and as of 7 a.m., there is a band of showers and storms in south-central Minnesota bringing beneficial rain.

While that area is diminishing, more storms are expected to develop in the afternoon, continuing into the overnight. Precipitation is possible anywhere, but the best chance is in central Minnesota. 

Unfortunately, that is also the most probable area for severe weather in the evening and overnight, with large hail the primary risk, but damaging winds and isolated tornadoes are also possible.

Strong storms continue to be a threat through Wednesday, as the heat also becomes more dangerous. 

That extended forecast will be updated around 9 a.m.
