Share story

It’s the last full weekend of August. How did that happen exactly?

This weekend is a split weather decision. Saturday will be the sunnier, nicer day this weekend. Clouds increase Sunday. Scattered showers and thunderstorms roam the Upper Midwest Sunday night and Monday. The Canadian GEM model paints rain areas moving from west to east across Minnesota Sunday and Monday.

September preview next week

It’s the time of year when anemic summer cool fronts soon morph into brisk cold fronts as they sweep through Minnesota. Monday’s cool front brings hints of early October. Highs in the upper 60s and low 70s will feel different around the Twin Cities next week. Lows in the low 50s make for good sleeping weather.

Lows in the 30s and frost visit northern Minnesota again early next week. Frost is common in northeast Minnesota in late August. 

Frost can occur at ground level even with temperatures in the upper 30s at the 5-foot NWS instrument shelter level. 

The average date for the first 32-degree temperatures in northern Minnesota favor early to mid-September. The average date for the first 32-degree temperature in the Twin Cities in fall is early October.

Warmer Labor Day weekend?

The medium-range forecast maps suggest a return to summer for Labor Day weekend. Highs in the (upper?) 70s look likely Saturday and Sunday. National Oceanic and Atmospheric Administration’s Global Forecast System model pushes highs back into the 80s by Labor Day. Other models are not as optimistic. We’ll see.
