Meteorological summer winds down

I had to do a calendar double take Monday.

The Minnesota State Fair starts in just 10 days. That’s next week. Our annual pilgrimage through the season we call meteorological summer is in the final three weeks. I saw hints of red in some sumac in southwestern Minnesota last week. 

Preview of coming attractions.

But late August and September can bring some of the year’s finest weather to Minnesota. It’s a bittersweet reminder that summer is all too fleeting at 45-degrees north latitude. In the Twin Cities our average daily high lingers at or above 80 degrees until Aug. 23. It hovers at or above 70 degrees until Sept. 21.

Get out there Minnesota.

Spotty thundershowers Monday

Our morning fog Monday is a product of longer nights, and lingering summer dew points in the 60s. We burn off the fog, but that moisture will be recycled into a few spotty thundershowers Monday afternoon. The best rain chances favor northwest and southeast Minnesota.

Cool front by Wednesday

Weather systems are loosely organized this time of year. No powerful cold fronts or intense late summer heat waves lurk on the maps. 

A weak cool front blows in drier air with dew points in the 50s by Wednesday and Thursday. Thursday looks like one of the best weather days of the year in Minnesota with bright sunshine, highs in the upper 70s and dew points in the 50s.

Savor it. Summer-like heat and humidity return this weekend.
