Freezing temperatures will bring down the curtain on MN growing season

Publish date:

If there's a horticultural version of "Auld Lang Syne," this might be the time to sing it.

Forecasters expect temperatures to fall overnight into the 20s and lower 30s by Saturday morning. all the way down to Minnesota's southern border, bringing an end to the growing season.

The freeze warning extends from Stearns County south and east into Wisconsin and Iowa.

The National Weather Service says the warning means "sub-freezing temperatures are imminent or highly likely. These conditions will kill crops and other sensitive vegetation."

But what a growing season it's been.

"Bumper" and "bin busting" are common descriptors of the corn and soybean crops Minnesota farmers are harvesting. The Rochester Post Bulletin reports the harvest in southeastern Minnesota looks like it will be the biggest on record.

Of course, outdoor plants are already just a memory in some parts of Minnesota. Frost advisories started appearing before September ended and the Weather Service says snow showers are possible in northeastern Minnesota Friday night.

Warmup ahead

This weekend's drop below freezing is likely to be short-lived, forecasters say. In fact, the Weather Service says shirtsleeve weather is around the corner, as temperatures climb into the 70s in the Twin Cities on Monday.

AccuWeather says highs in the lower 70s are about 15 degrees warmer than average for mid-October.

But they won't last long, either. Highs are expected to be back in the 50s by Thursday.
