We have a busy forecast ahead for KELOLAND this weekend with areas rain, freezing rain, sleet, and snow. Here’s the breakdown for the four regions of KELOLAND.
Southeast: Today, look for increasing clouds with highs near 40 in Sioux Falls. Winds will be from the southeast. Rain showers could start to develop on radar late in the afternoon, but the best chances of rain will hold off until early this evening. The rain will expand overnight and some areas may hear some thunder, mainly south of I-90. The Brookings area will close to freezing, so we’ll watch the potential for freezing rain along and north of highway 14.
Tomorrow will start warm enough for rain, but a transition to snow will take place along a Chamberlain to Huron line through the morning. This will expand south toward Sioux Falls by early evening. A second area of sloppy wet snow could also develop closer to the main low track in eastern Nebraska and western IA Saturday night. We’ll keep an eye on that trend for any changes. The trends clear the area Sunday morning.
Northeast: Look for increasing clouds and highs only in the lower 30s today in Watertown and Aberdeen. As rain develops this evening to the south, it will lift north and icy weather is looking likely for parts of the northeast. At most risk will be Sisseton-Watertown-Milbank-Ortonville areas. A winter storm watch has been posted for this area after 6pm through tomorrow for the potential for ¼” or more of ice. Places farther west toward Redfield and Huron could also see some ice, but it still too hard to say if it will enough to cause significant problems. Stay tuned.
Aberdeen could see a mix of snow and freezing rain, but as colder air filters in from the north, snow will be more likely through the day and then end by Saturday mid afternoon. No watches are posted for Aberdeen at this time. There is a risk of 3+” of snow in the northeast corner of SD, but freezing rain may cut in to the snow totals.
Central: Mostly cloudy skies will develop today with highs in the 40s. As rain begins in southcentral SD, a mixed bag of snow, freezing rain, and rain will occur during the overnight hours. The strongest forcing for heavier precipitation will be focused closer to the Nebraska border. There are winter storm watches and blizzard warnings in western Nebraska, so we’ll need to watch this area of snow to see if crosses the border into SD with some heavy wet snow. There is a risk of 4+” around Winner and Valentine, but a mix of sleet and freezing rain could cut into those totals. A frozen mix of precipitation in southcentral SD will change to all snow Saturday morning before tapering off to flurries by Saturday night.
West: A wintery mix of rain, freezing rain, and snow will develop in far SW SD later today. Temperatures will be in the 40s this afternoon in the west, so at the start, all modes of precipitation look possible into early this evening. At this time, the strongest forcing for heavy precipitation looks to be western Nebraska. Some snow accumulation is expected in southwestern SD, but due to the uncertainty of rain vs. snow, no advisories have been posted as of Friday AM. NW winds 20-40mph will pick up late tonight and tomorrow in western SD, so any snow that does fall could blow around a bit. Again, the risk of more than 4” in Rapid City is low, but we are still monitoring the latest data. Travel with care and stay tuned to the latest forecasts.
The weather trends look quiet early next week with warming trends ahead by late next week.
