A brief round of above average temperatures and dangerous heat is forecast for the Northern Plains and Midwest late-week. A large dome of high pressure overhead, making for a “ring of fire” weather pattern across the nation is the main factor of this warmup. During the weekend, however, a cold front will begin to cut across the region, while will allow for a reprieve from the heat.

This Wednesday, high temperatures will surge into 90s across most of the Northern Plains and western sections of the Midwest. Some towns may even touch 100 degrees in the afternoon. Now when you combine that with the humidity, it will feel even hotter with heat indices mainly between 95 and 105 degrees. Hence the issuance of Heat Advisories for much of this region. Temperatures will be slightly cooler but still above average just to the east across the rest of the Midwest with highs generally into the mid to upper 80s.

Temperatures will creep up by a couple degrees across the Midwest as that heat drifts to the east on Thursday. Now while the Central Plains will bake with high temperatures into the 90s and 100s, the Dakotas will turn cooler with highs only in the 70s and 80s due to a weak cold front passing through. That will be the only “cool spot” — if you even want to call it that. Otherwise, the rest of the region will experience temperatures up to 10 degrees above average.

That “cool spot” will shift a bit more to the south, affecting southern South Dakota and much of Nebraska. Meanwhile the Northern Plains and Midwest will be in for another hot day overall. High temperatures will soar into the mid to upper 80s to the 90s. The high humidity will make it feel even warmer than that with heat indices approaching 100 degrees.

Saturday will be the final day featuring the widespread warmth. High temperatures for most locales will be right around that 90 degree mark, although it will be slightly cooler in the Upper Midwest. That translates to temperatures generally up to 5 degrees above average.

Then beginning Sunday, the Northern Plains will cool off with temperatures up to 10 degrees below average. The same will follow suit in the Midwest by Monday thanks to the passage of a cold front.
