Heat wave could bring prolonged sauna-like conditions to Minnesota

The National Weather Service says the heat could arrive in a week.

Since spring in Minnesota felt like summer, what's summer going to feel like? So far, so good, but Mother Nature has plans to crank up the heat beginning late next week. 

We're talking about the kind of heat that you can fry an egg on a sidewalk with. 

According to the National weather Service, the "potential of heat and humidity remains on track" next weekend and into early July, with temps into the 90s coupled with high humidity leading to heat indices of 100-105 degrees. 

Meteorologist Paul Douglas described it as "jungle-like heat" in his blog for the Star Tribune, noting that rounds of severe storms will accompany the heat. 

Bill Borghoff, a senior meteorologist with the Twin Cities office of the National Weather Service, tweeted that the heat wave could be prolonged, showing a graph that projects temps of 90+ degrees for nine consecutive days.

Providing some hope that it won't happen, though, is MPR meteorologist Paul Huttner. He doesn't see any "major heat spikes" in the long-range forecast models, suggesting that temps might approach 90 late next week.

The average high temperature in the Twin Cities so far in June is 79.6 degrees, which is only slightly warmer than it was in May when MSP Airport recorded an average daily high temperature of 78.4 degrees. 

The airport has recorded temps of 90+ degrees eight times this year, including six straight days in May (24-29) and twice in June (15, 17). 

Regardless of whether it gets as hot as forecasters are hinting, it's definitely going to get warmer as get close to the Fourth of July. 

In the shorter term, Saturday is going to be gorgeous with isolated thunder in western and northern Minnesota, followed by increasing rain chances across the state Sunday-Tuesday.
