Tuesday will be the warmest day of the year so far as temperatures creep toward 90 degrees for much of the state.

People living in the Minnesota River Valley and southern Minnesota have the best chance at topping 90 Tuesday, while people in the northern part of the state will likely see temperatures in the 80s, the National Weather Service notes.

On average, the Twin Cities hits 90 degrees 13 times each summer, the Minnesota Climatology Working Group notes.

Last year, the Twin Cities only saw two days at or above 90 degrees in the entire summer, with the hottest day of the year coming July 21, 2014, with the mercury hitting 92.

Statistically, the hottest day of the year comes between July 11-15 for the Twin Cities, MPR News reported. The average temperature in the Twin Cities this time of year is in the mid-70s.

But the taste of summer won't turn into a scorching heatwave, the Star Tribune's weather blog notes. A cold front is expected to move through Tuesday, dropping temperatures into the 70s and 80s for the remainder of the week.

This could produce some storms in central Minnesota Tuesday, MPR News' Updraft blog says.

The weather for the rest of the week remains unsettled, with heavy rain and thunderstorms expected for much of the area Thursday as well.

There's also a chance for showers and storms Friday and this weekend, the Pioneer Press says.
