We have a very busy forecast across KELOLAND with a number weather headlines.
First, south winds are increasing across much of eastern KELOLAND with gusts over 30 mph in many areas. Blowing and drifting snow has been reported from Redfield to Clark, east to Milbank. This is just one example area and visibility will be reduced to 1/8 mile in some areas.
Temperatures will be the bright spot of the forecast as warmer air arrives. Rapid City will be near 50, while Pierre will be in the lower 40s, and Aberdeen and Sioux Falls will be close to freezing by early to mid-evening. Some very light mixed precipitation is also possible, but amounts should be just a trace to a couple hundredths of an inch.
Also, starting late Friday afternoon, strong NW winds will accompany a cold front that will sweep across KELOLAND. We are concerned about blowing snow with this feature tonight, especially the closer you live to the North Dakota border. Blizzard warnings have been posted for North Dakota this afternoon and tonight, so we’ll monitor those conditions as well.
Breezy NW winds will continue much of Saturday and temperatures will be falling during the day. The extreme cold will filter into KELOLAND on Sunday, as temperatures stay below zero all day from Aberdeen to Sioux Falls. Wind chills by Sunday night will range from -40 to -55 as air temperatures drop into the 20s below zero Monday morning.
Monday’s high temperatures will be -10 to -15 in many areas east of the James Valley. This will likely be the coldest day since January 10th of 1997. We do expect some improvement Tuesday, with better weather back by Wednesday.
