Autumn is about to ride into Minnesota on a heat wave.
On Friday it'll be especially muggy in the Twin Cities, where the National Weather Service has issued a heat advisory from 1 to 7 p.m.
That means it's going to be so hot that it can be dangerous for people.
Forecasters expect a high temperature in the lower 90s, but the humidity will make it feel like 100 in the Twin Cities and near St. Cloud by mid-afternoon.
Heat illness is very possible, especially for people who are active outside. The CDC has info here on the symptoms of heat stroke and heat exhaustion, along with what to do if you have them.
The main things you should do, though, are:
- Drink lots of fluids
- Stay in air conditioning if you can
- When you're outside stay out of the sun
- It's a good day to check on people who might need help
Further north it'll still be warm and humid. Expect temps in the upper 70s or low 80s through the Iron Range and around the Duluth area.
The very northwestern region of the state is getting a cool down before anyone else, with places like Hallock and Roseau in line for highs in the upper 60s.
Is 90 degrees in September rare?
The Weather Service says in the Twin Cities it happens about once every three years.
It would be pretty weird to have the first day of fall be the hottest day of the year. The forecast has the Twin Cities missing that by a few degrees, but it's possible in St. Cloud, where this summer's highest temperature was 92.
Storms could come in afterward
Friday night could bring severe thunderstorms strong enough to cause wind damage.
High temperatures are still expected to be in the 80s over the weekend. Rainfall could amount to a few inches, though, especially in a band through the middle of the state.
We're in store for a cool down next week. The Twin Cities forecast shows highs just in the 60s by Tuesday.
A road trip suggestion
One way to beat the heat: take a long weekend and take to the road. Highway 10, for example.
