Rapid City, South Dakota

POLAR VORTEX!! Now that I have your attention, let’s go visit a city that’s significantly warmer than the eastern half of the country.

At 8:52pm MST, the temperature at Rapid City, SD was 25 degrees under fair skies. High pressure over the Upper Midwest will continue to slide off to the east as a lee trough starts to sag into the western Dakotas by midday Thursday. A system dropping through the Rockies will continue down to the Four Corners region, but a piece of energy could kick up some scattered snow showers as it passes by the Rapid City area Thursday evening. If anything does fall, it shouldn’t amount to much. On Friday, a storm system is expected to strengthen and lift through the Mid-MS River Valley up into the Great Lakes, largely bypassing the western Dakotas. However, another very weak disturbance could kick up some flurries/snow showers in the region. And once again, it won’t amount to anything if it does occur. Overall, a couple of relatively benign days.

Thursday: Increasing clouds late, slight chance of a few evening flurries. High 43, Low 21.
Friday: Another chance of a few evening snow showers. High 41, Low 22.

TWC: Thursday: Mostly sunny. High 40, Low 23.
Friday: Mostly sunny. High 35, Low 25.

AW: Thursday: Partly sunny and milder, some evening snow showers. High 44, Low 20.
Friday: Some sun, breezy and colder. High 37, Low 22.

NWS: Thursday: Mostly sunny, slight chance of evening snow shower. High 44, Low 20.
Friday: Partly sunny. High 41, Low 24.

WB: Thursday: Mostly sunny. High 43, Low 20.
Friday: Partly sunny. High 40, Low 24.

Here we see a low cloud deck in the eastern Dakotas, possibly set to obscure some people’s viewing of some auroras expected tonight. Curse you clouds!
