Storm Center Update Sunday AM - December 17

Today will be a little cooler for some, but still above the climate average for mid-December, with skies partly to mostly cloudy to start the day. But as surface high pressure builds, skies should clear out by the evening. Highs will be in the upper 30s for east KELOLAND where clouds will stick around a little longer with temperatures reaching the low 40s in west KELOLAND. Winds should be very light.


This week will also start out warm. Monday we expect clouds to return, but temperatures will be way above normal, in the mid to upper 40s for the east while the west reaches the 50s again. Tuesday might be a touch breezy, but high temperatures will still be in the 40s.


Wednesday will be partly cloudy and warmer ahead of a strong cold front. Highs will be in the upper 30s to 40s. Snow will start in northern South Dakota late in the day and move south through the nighttime lasting into Thursday.

Forecast models are projecting the arrival of some very cold arctic air Thursday. It will be windy with a good chance of snow across KELOLAND on Thursday. It’s too early to realistically talk about amounts right now, but if this storm plays out like the snowstorm from earlier this month, a few inches of snow will be possible. Temperatures will be sharply colder, about 20 degrees colder than Wednesday’s highs. Right now we’re forecasting highs in the teens in northern South Dakota to the low 20s in the south.


And it looks like the temperatures will remain in that same neighborhood for the rest of the week and Christmas weekend. So we may actually end up with a “normal” Christmas with snow on the ground and cold temperatures in the teens and 20s.
