More Cold… A Winter Storm by Late Week

The bitter cold continues and we continue to monitor a winter storm system that could bring significant snowfall to our region late this week into this weekend. A Winter Storm Watch has been issued for much of the region including the Sioux Falls area. There is a lot going on in the weather today.

I’ll start with the cold. Frigid temperatures continue to impact most of our region this morning. While most places are actually above zero, strong northwesterly wind gusts have kept the windchill factor below zero for most of the night. Today will be mostly sunny with afternoon high temps in the single digits. Northwesterly wind gusts to 25 mph will keep the wind chill factor below zero for most of the day. Tonight will be clear and cold with lows dropping below zero. A Wind Chill Advisory is in effect for parts of eastern South Dakota and western Minnesota tonight for wind chill values dropping to -20° to -30°.

Now the snow: A Winter Storm Watch has been issued for Friday and Saturday and includes much of central and southern South Dakota and southwestern Minnesota. We will start with a brief, initial shot of snow – up to an inch in a few places – during the day on Thursday. The main event will roll into western South Dakota late Thursday night and move east by Friday morning. Moderate to heavy snow will fall through the day Friday and into Saturday. While it is still a little early to get specific, as of right now I think we could see a band of at least 5 to 8 inches along and north of I-90.

While the snow will end on Saturday, strong northwesterly wind gusts will create blowing snow on Saturday and Saturday night. Keep in mind, temperatures throughout this event will be very cold, so the snow will be light and fluffy and easily blown around.

By Sunday morning, temperatures will drop to near record lows. Sioux Falls could fall to -25° while parts of northern South Dakota get close to -30°. That’s actual temperature, not windchill. The good news is that it does look like we will warm up a bit next week.

Stay tuned for the very latest on this developing winter storm system. I will have updates and get more specific with snow totals and the track of the storm as new information rolls in.

Cold Continues… Snow Possible Late this Week

Bitterly cold temperatures will continue to plague the region over the next several days. Today will be mostly sunny with highs ranging from the low teens in Sioux Falls to the mid teens across central South Dakota. Temperatures will stay well below average through most of the week and then they will warm up slightly ahead of our next system.

Our next weather system has the potential to trump the cold as our big weather story of the week. Snow will develop late Thursday and Thursday night and continue through Friday and into Saturday. Several inches of accumulation will be possible followed by strong wind and blowing snow. While it is way too early to get specific with the snow accumulation forecast, I think that some parts of our KSFY coverage area could get at least 4 to 6 inches. Some models are suggesting even more. Again, that is very preliminary and there is a lot that could change throughout the week. Stay tuned. I’ll have updates as the system develops.

After that system passes, we’re going to get even colder! By Sunday morning, parts of northern South Dakota could drop to near 30 below zero.

Hang on… It’s going to be an interesting week!

Rain & Snow Today… A Warm, Sunny Weekend AheaD

The rain, freezing rain and snow has ended in most places. Everything is still wet though, and with temperatures hanging around the freezing mark, there will be slippery roads and sidewalks this morning. Take your time and be careful.

Today will be cloudy and cool with highs in the mid to upper 30s. Thanksgiving day will be cloudy and slightly warmer with a chance of light rain and snow in the afternoon and evening. We could get a little (less than a half inch) sloppy wet snow in Sioux Falls. Parts of northern South Dakota into southwestern Minnesota could get an inch or more.

Black Friday and the weekend will be sunny and warmer. High temps will reach the mid to upper 40s on Friday, Saturday and Sunday. Parts of central South Dakota will warm into the 50s. Another system will roll in late Sunday, bringing rain Sunday afternoon followed by rain and snow Sunday night, Monday and Tuesday. If you are going to be traveling this weekend and plan to return on Sunday, keep an eye on the weather because roads could get icy by late Sunday afternoon.
