Nice Taste of Fall Arriving This Week: Upper Midwest to OH/TN Valleys
Attention is instead becoming turned to an arriving cold front that will bring yet another round of rain and storms to the dry Midwest but also a welcome taste of Autumn. The front will be entering into the northern Rockies (MT) and into the Upper Midwest, Tuesday. Some storms will develop ahead of the front and near a surface
low across eastern SD and into Minnesota and Iowa. The front will spread into the Great Lakes, Wednesday, but will make little initial head way south. That will wait until a secondary piece of energy swings around and out of Manitoba, Friday. At that time, the front will push east and south and by Saturday, it will stretch from Ohio into northern Texas.
Behind the front, it will be very nice with highs only into the 60s across much of Upper Midwest and Great Lakes. Morning lows will be down into 40s. A few spots may even drop into the upper 30s across far northern Minnesota and the U.P. of Michigan.
The front will exit the Atlantic Coast and Florida on Monday. This will allow the very comfortable air to reach as far south as the Gulf Coast.
SEVERE WEATHER Potential
As the initial piece of energy pulls out of the Northern Rockies and into Minnesota and the Great Lakes, Tuesday-Thursday, a few strong to severe thunderstorms with gusty winds and some hail are possible. Areas included will generally be along and north of I-80 from Lincoln, Nebraska to Toledo, Ohio.
