Sioux Falls, SD
There’s good news and bad news in the weather.
Friday will be a nice day with highs in the 40s in much of southern KELOLAND with 20s in the far north. The weather will start going down hill Friday evening as a low pressure central develops over north-central South Dakota.
Showers may develop around Sioux Falls and the southeast Friday evening, with snow developing in the Aberdeen areas starting as early as late Friday afternoon. As the evening progresses through 9 p.m., Pierre and Rapid City may see a light mix of rain or snow with falling temperatures and gusty northwest winds as arctic air pours into KELOLAND. Conditions will deteriorate rapidly in eastern KELOLAND after midnight with the worst weather in MN by the morning.
Blizzard watches have been issued for most of SW Minnesota, with snow and blowing snow the problem.
The snow will also accumulate in eastern KELOLAND, basically north and east of line from Mobridge to Vermillion. Sioux Falls can expect 1-3” of snowfall with blustery winds from the north at 20-40 and falling temperatures through the single digits all day. Look for around 2-5” for the northeast including Watertown and Aberdeen, with our Minnesota counties, including the Marshall and Worthington areas seeing 3-6” with lots of wind and whiteout conditions. Travel may become nearly impossible Saturday in portions of southern Minnesota and also northern Iowa from Spencer and points east.
Bitterly cold winds will continue Saturday afternoon, but diminish with time Saturday night and Sunday. Lows will drop below zero in all of eastern KELOLAND and highs will be in the single digits in both Aberdeen and Sioux Falls.
Light snow will return to central and eastern KELOLAND Monday and Tuesday with a slow warming trend.
Stay tuned for the latest forecasts through the day.
