Tuesday’s forecast in Minnesota

The forecast:

Tuesday starts with areas of morning clouds and fog before sunshine returns through the afternoon.

Temperatures climb into the upper 80s and low 90s across much of Minnesota, while the Twin Cities metro tops out at around 90 degrees. Along with the humid conditions, heat index values could approach the upper 90s. 

An air quality alert is in effect for the Twin Cities metro from noon to 9 p.m. due to elevated ground-level ozone levels. A heat advisory is also in place for parts of northeastern Minnesota on Tuesday. 

Most of Tuesday stays dry, but a line of storms is expected to approach from the west late tonight.

Storm chances late Tuesday night 

What to expect:

Storm chances are possible between 10 p.m. and 5 a.m. as a line of storms moves from the Dakotas into Minnesota.

The storms are expected to weaken as they move east, but a few stronger cells are possible. Much of the Dakotas and western Minnesota are under a level 3 enhanced risk for severe weather. Central Minnesota is under a level 2 slight risk, while the Twin Cities metro remains under a level 1 marginal risk.

These storms could produce hail up to 1 inch in diameter, heavy downpours, and a brief spin-up tornado.

The Twin Cities metro, much of Wisconsin, and parts of Iowa and Illinois are under a level 3 enhanced risk for severe weather. Damaging winds, large hail, and isolated tornadoes could be possible.

What's next:

The passing cold front brings cooler and less humid air on Thursday, though some leftover showers are still possible. 

Temperatures settle back into the 70s on Saturday and Sunday, with a mix of sunshine and clouds making for a much more comfortable stretch of weather.
