Thursday is the beginning of a summer-like heat wave in Minnesota. Temps will rise into the upper 80s and low 90s and it'll feel even hotter and stickier thanks to high humidity and dew points in the mid-60s.
All that juice in the atmosphere will lead to some strong to severe storms later in the day, with the main severe threat being large hail and damaging winds across western and north-central Minnesota.
According to the National Weather Service Grand Forks, a line of storms is expected to develop mid-afternoon, stretching from Lake of Woods down toward the Detroit Lakes area.
It'll quickly move east, paving the way for a second line of storms to develop over central North Dakota, those of which have the best chance of bringing large hail and strong winds.
"The best chance of thunderstorms across central/southern Minnesota will occur by the late afternoon, and evening hours. West central Wisconsin may need to wait until after dark for most of the activity to enter it's area."
