Happy autumnal equinox to all who celebrate! At precisely 1:19 p.m. CDT, the sun’s direct rays will fall on the equator, marking the official start of autumn. Although, as far as the atmosphere is concerned, “meteorological autumn” kicked off closer to Sept. 1, at the end of the warmest 90 days of the year, on average. Hey, what’s a few weeks among friends?

It’s not yet 50-50 daylight-darkness. Even on the equinox, day isn’t exactly 12 hours because of atmospheric refraction and the sun’s visible disc adding a few extra minutes of light. “Almost interesting, Paul, thank you.”

After a little early fog, a stray sprinkle or shower can’t be ruled out later Monday. Winds will be unusually light for late September — under 8 mph most of the day.

A good day for a bonfire, except up north. Pockets of dry weather persist from Sandstone and Wadena north to Bemidji. Lake water levels are falling again.

I see dry weather the next one to two weeks. Temperatures in the 70s should be the rule. Maybe a few 80s in early October? Heck, why not?
