First fall freeze-up expected tonight
Willmar – The first serious cold snap of the season is expected early Saturday morning when temperatures across west central Minnesota dip below 32 degrees.
The National Weather Service issued a freeze warning for much of the region, indicating that sub-freezing temperatures are “imminent” or “highly likely.”
The warning begins at 3 a.m. and last until 9 a.m.
The low temperature is expected to be around 30 degrees, which is cold enough to kill crops and other sensitive vegetation.
Chris O’Brien, a forecaster with the National Weather Service in Chanhassen, said getting this cold the end of September isn’t all that unusual.
“People are saying it’s too early. It shouldn’t be happening at this time,” he said. “But it’s about average. It’s right on time.”
After the one-day freeze, temperatures are expected to rebound to the mid-50s and 60s this weekend and next week.
Gardeners hoping to preserve their flowers or vegetables a little longer should take care to bring potted plants inside and cover row crops like tomatoes and peppers with blankets.
The freeze will also increase fall tree colors.
