Areas of storms through Saturday evening; toasty much of the next week

Heat and moderate humidity will stay with us this weekend and build for much of next week.

Widely scattered storms through Saturday evening

Widely scattered showers and clusters of thunderstorms popped up in parts of western and northern Minnesota during Saturday’s heating. There are no meteorological features to organize the convection, so they will be hit-and-miss. Some of us will get wet but most of the state will not.

Strong thunderstorms with heavy rain are well to the northwest of the Twin Cities late this Saturday afternoon. A couple severe thunderstorm warnings have been issued. Wind gusts to 60 mph were reported in Rothsay in Wilkin County of west central Minnesota.

They are sliding very slowly southeast, generally north of Interstate 94, toward the St. Cloud-Foley-Milaca area. Some of these storms will be in or near the Twin Cities area Saturday evening.  Severe weather is possible but a major outbreak is unlikely. Heavy rain is possible and would be welcome.

Hot Sunday

Sunday will be toasty. Expect widespread high temperatures from the mid 80s to low 90s, but cooler near Lake Superior. The Twin Cities should get enough sunshine to reach about 90.

Hottest Monday and Tuesday

Monday and Tuesday look like the hottest upcoming days—real scorchers. A hot air mass and July sun will push our temperatures well above normal. High temperatures are likely to range mainly from the upper 80s to mid 90s both days, but western Minnesota could easily flirt with 100 degrees, especially on Monday. Twin Cities highs should be in the mid 90s, with humidity, both days.

Storms far north Monday?

Isolated thunderstorms are possible near the Canadian border on Monday, but forecast models are not that convincing.

Strong storms possible Monday night-Tuesday

An upper air wave from the northwest will trigger strong thunderstorms beginning Monday night in northwest Minnesota. Some storms could become severe into northwestern Minnesota by late Monday evening, then slide southeast toward the Twin Cities during the night.

The Storm Prediction Center has posted a slight (yellow; level 2 of 5) risk of severe weather for Monday (note: Monday goes until 7 a.m. on Tuesday for SPC outlook purposes). The slight risk is surrounded by a marginal (dark green, level 1 of 5) risk area. The light green color indicates areas of possible non-severe thunderstorms.

Storm Prediction Center outlooks become more uncertain as to probability of occurrence and location of severe storms after the third day. The day 4 outlook for Tuesday, which begins at 7 a.m. on Tuesday, indicates that weather factors are likely to create at least a chance of severe weather that day for central to eastern Minnesota and all of Wisconsin to Michigan and northern Indiana later. This outlook can best be described as a broad-brush early alert to the possibilities of severe weather

Rest of the week

Temperatures will cool back to near normal on Wednesday before heating up again for the rest of the week. The Twin Cities are likely to warm back into the low 90s by Friday and Saturday. And yes, there will be humidity, especially next weekend.
