Today will be a very mild day in KELOLAND with highs ranging from near 70 in Rapid City to around 37 in Aberdeen. Sioux Falls will be in between with a high near 45 and lower 60s are likely around Pierre. Winds will be around 5-15mph, so enjoy a nice day and get some fresh air.
The pattern starts changing tonight as light freezing rain moves into northeastern SD. We have a freezing rain advisory for Aberdeen-Sisseton-Watertown-Ortonville areas after midnight. That will make travel difficult in those areas tomorrow morning. Some of that freezing rain could spread farther south, so even the Brookings and Marshall areas will want to stay tuned to more forecasts later today.
Temperatures tomorrow will range from near 70 in the southwest, to around 30 in the northeast corner. Any freezing rain in the morning will mix with snow through the day in the northeast corner of KELOLAND as colder air starts to slide south. That colder air will filter through most of KELOLAND Friday night and Saturday. NW winds will also get stronger by the afternoon in Rapid City.
The next clipper system will enter western KELOLAND Saturday, with more precipitation on Sunday and Monday. The track of the low pressure system is still uncertain, so we’ll keep an eye on that to determine where the heaviest rain and snow will fall. Winds will pick up from the northwest by Monday, so any snow that does fall could be blowing around once the system exits the region. It’s more likely that northern KELOLAND will see more snow than the south, so we’ll have more on that later today.
