Warming through weekend: 100-degree heat index by Monday

After a pleasant respite from average temperatures this week, the hot summer weather Minnesotans are used to this time of year is returning this weekend and stretching into next week, the National Weather Service says.

While Friday's forecast calls for highs between 75-85 degrees in the Twin Cities, temperatures will begin to climb Saturday.

"Much warmer air will return to the region this weekend along with increasing humidity," the weather serice says, with forecasted highs of 80-85 degrees Saturday in the metro, and 85-90 degrees Sunday. The weather service says there's "small threat" of thunderstorms Saturday, and again on Sunday afternoon and evening.

Highs in the northern part of the state, meanwhile, will be in the 70-80 degree range this weekend, with a chance of scattered thunderstorms, the weather service says.

Monday will reportedly bring highs of 85-95 degrees and a high heat index for much of the state.

"The heat and humidity will peak on Monday with afternoon heat indices reaching 100 to 105 across central and southern Minnesota and from 95 to 100 in west central Wisconsin," the NWS says.

MPR's Paul Huttner says this week's low dew point readings could climb to 70 percent early next week, making it feel sticky.

The weather service says a "much greater threat for thunderstorms" will also arrive Monday night and Tuesday.

The warming trend and humidity bring to an end what some meteorologists deemed "perfect" weather in the past few days.

The Star Tribune's Paul Douglas says smoke from the Canadian wildfires will also be drifting over Minnesota in the coming days.

"As you slather on your SPF 50 sunscreen and stare up at a hazy-milky blue sky, realize that smoke from Canadian wildfires is drifting over Minnesota – swept along by jet stream winds aloft," Douglas writes.

The meteorologist notes that while "the smoke plume is too high to smell anything unusual," a "few cherry-red sunsets are possible in the days ahead."

KARE 11 meteorologist Sven Sundgaard posted a look at the smoke in the atmosphere over Minnesota on Twitter.
