July heat continues; chance of isolated storms Sunday afternoon

Sunday is going to be a hot, muggy one. Look for high temperatures across Minnesota mainly from the mid 80s to the mid 90s, with those mid 90s most likely in northwestern Minnesota. The North Shore will be cooler as a breeze blows off Lake Superior. The Twin Cities should warm to near 90.

Lingering instability might allow the daytime heating to kick off a few isolated thunderstorms Sunday afternoon including near the Twin Cities, but most of us will stay dry.

There will be just a marginal (dark green, level 1 of 5) risk of severe storms Sunday evening in the northwestern corner of Minnesota around Hallock and Roseau.

Heating up Monday and Tuesday

The heat will really crank up on Monday and Tuesday. Monday looks to be the hottest day. Highs are likely to range from around 90 in the northeast to about 100 in west central Minnesota. The Twin Cities seems likely to have a high near 98 on Monday. Tuesday should be a bit less toasty.

Chances of storms

Unsettled weather will return on Monday and Tuesday. Scattered showers and storms are likely across northern Minnesota on Monday. By Monday night, the threat of severe weather will spread into northwestern Minnesota. A slight risk (yellow, level 2 of 5) has been posted for the northwestern Minnesota for Monday night. It is surrounded by a marginal (dark green, level 1 of 5) risk. The light green represents possible non-severe thunderstorms.

The chances of strong/severe storms will slide farther southeast for Tuesday. Then the slight risk will cover central to east central Minnesota, including the Twin Cities, and most of Wisconsin.

A cold front will cool the state closer to normal for Wednesday.

Then expect the heat to build again later in the week.
