As we head into the work week, the weather conditions are about the same as we’ve been forecasting for several days. Also as expected, many schools in eastern KELOLAND have cancelled classes. See our Closeline for details.
Northwest winds will continue to blow at an average 15-30 mph overnight and most of the day tomorrow. It is a little unusual for such strong winds to accompany such a cold air mass, but that is the case here because upper level winds are driving the cold air down on us from Canada. Areas of blowing snow (or possibly isolated snow flurries) will also be possible. We’ve received reports of blowing snow in NE South Dakota. A Wind Chill Warning is posted across the region until Tuesday morning.
Here are the details. Our overnight temps will be in the 20s below zero in eastern KELOLAND. Even the Rapid City, which has been spared most of the arctic air recently, will reach 18 below.
Tomorrow temperatures will remain well below zero. We’re forecasting teens below zero for daytime highs.
Tuesday will be cold in the morning, but with diminishing winds and a bit of sunshine, we should see highs in the single digits.
I’ve saved the best for last: a gradual warming trend the rest of the week. In fact, we’re forecasting something of a thaw next weekend…30s!
