MIDWEST — A strong cold front is expected to plow through the Upper Midwest on Tuesday and Tuesday night, dropping temperatures by 20 degrees in just six hours. The sharp change will bring an abrupt end to the mild weather the region has enjoyed in recent weeks. Temperatures will fall back to near normal for the second half of the week, with multiple freezes expected across the region.
Cold Front Arcs From Lake Superior Through Iowa and Missouri
The cold front is forecast to stretch in a long arc from near Lake Superior south through Wisconsin and Iowa before curving southwest across Missouri and into Kansas. Air on either side of the boundary will be dramatically different as the front moves east.
Behind the front, temperatures across Minnesota and the Dakotas are expected to sit mainly in the mid 30s to low 40s. Western Iowa and Nebraska fall into the 40s, while areas farther southwest in Kansas hold in the upper 40s to low 50s.
Warm Air Holds East of the Front Before the Big Drop
Ahead of the front, much warmer air remains in place across Wisconsin, Illinois, Michigan, and Indiana. Temperatures in these areas are shown mainly in the low to mid 60s, with some readings reaching the upper 60s and near 70 degrees in parts of Illinois and Indiana.
That sharp contrast is what will drive such a fast temperature drop. Communities near the front could go from the upper 50s or low 60s to the upper 30s or low 40s within just a few hours once the boundary passes Tuesday night.
Near Normal Temperatures and Multiple Freezes Later in the Week
After the front passes, temperatures will settle back to near normal for early November during the second half of the week. Multiple freezes are expected, especially during the overnight and early morning hours across Iowa, Minnesota, and Wisconsin.
While this type of cold is typical for the time of year, it will feel like a major change compared with the mild stretch that dominated late October. Residents should be prepared for frosty mornings and colder afternoons once the front clears the region.
Prepare for Gusty Winds and a Sudden Shift Tuesday Night
Strong cold fronts like this often bring gusty winds and a sudden shift in conditions as they move through. Anyone heading out Tuesday evening should dress in layers, as temperatures could fall quickly during the commute home.
Outdoor plants, garden hoses, and exposed pipes should be protected ahead of the freezes later in the week. Pet owners should also bring animals indoors overnight once temperatures begin dropping below freezing.
