Here comes our next ride on Minnesota’s weather roller coaster. 

A series of contrasting air masses will sweep across Minnesota in the next few days. Monday’s coolness gives way to another day near 90 degrees in southern and western Minnesota Wednesday. 

Another cold front sweeps south Wednesday night. The front will drive a line of thunderstorms across northeast Minnesota Wednesday afternoon.

NOAA’s Storm Prediction Center lays out a slight risk for severe storms Wednesday (map above) from northeast Minnesota to the Twin Cities and western Wisconsin. 

Many short-range mesoscale forecast models keep most of the storms north of the Twin Cities Wednesday evening. But a few develop possible isolated storms over parts of the Twin Cities after about 7 p.m. Wednesday evening. 

NOAA’s WRF model is among the most aggressive with the southward extent of storms along the advancing cold front Wednesday evening. The loop below runs between 4 p.m. Thursday and midnight. 

Thursday brings northwest breezes and a cooler air mass behind the front. 

Then brisk southwest breezes will pump temperatures higher again by Friday. Highs this weekend will reach the 90s once again across much of Minnesota. 

The Twin Cities has recorded 20 days of 90-degree heat so far this summer. That’s a full week more than the long-term annual average of about 13 days. It looks like we’ll add another two days to that total this weekend.

Forecast models differ on how long the heat may linger into next week.
