The upper Midwest and the Great Lakes get the ultimate taste of summer heat by midweek
chicago — It’s a tale of two seasons this week across much of the United States, as cold temperatures arrive in the West while temperatures warm in the Midwest and Plains, creating an adverse forecast for the northern tier.
In the northern plains, temperatures began slightly below average over the weekend. But starting Tuesday, a band of high pressure will move into the upper Midwest and Great Lakes.
Winds around the hills will shift warm southerly winds into the region, allowing temperatures to begin to warm across the plains and bring the final understanding of summer.

Omaha is expected to see a high temperature near 90 degrees on Tuesday and Minneapolis will reach the mid-80s by Wednesday.
“Finally, it’s (warm) across the upper Midwest and really spreading, and areas like Chicago will feel the last taste of summer as we head into Wednesday,” FOX Weather Meteorologist Kiana Lewis said.
High temperatures in the 80s to 90s are possible from the Dakotas to Ohio. The temperature in Sioux Falls, South Dakota, will approach 90 degrees on Tuesday with the heat increasing.
Cities including Columbus and Minneapolis could see highs in the low 80s midweek through Saturday.
How to watch Fox Weather
Chicago will still be a little cooler, but not by much. Temperatures are expected to reach the upper 70s Wednesday through the weekend in the Windy City.
The FOX Forecast Center said it is not uncommon for temperatures to fluctuate as the seasons change. Models indicate that these warm temperatures will continue across the region through the end of the week.
Cold weather invades the West
Meanwhile, fall is coming just in time farther west, where the first fall storm of the season will bring not only days of torrential rain but also a distinct autumn chill. Low temperatures across the northern Rockies and inland Pacific Northwest will drop into the 40s by the end of the week – even 30s in the higher elevations with the risk of snow on the highest mountain peaks.
