THIS IS A COPY OF AN EMAIL I SEND OUT TO JAY, BRIAN, AND BEN. JUST SOME THOUGHTS ON WHAT THE FORECAST MODELS ARE DOING. IT MAY OR MAY NOT REFLECT THE FINAL FORECAST. BE SURE TO VISIT OUR WEATHER PAGE FOR UPDATES. –SCOT MUNDT
Nice to see the sun in Sioux Falls this afternoon, but temps remained below average. Tomorrow’s forecast of 38° could end up being the warmest since February 17’s 44°. The last time Sioux Falls was ABOVE average was February 18 with 36°. Thursday’s average high is 39°!
Warm air will last into Friday, and then the fun focuses on the system for the weekend. GFS and EURO have picked up speed with things starting Friday night. Should come in as rain for south central and southeast KELOLAND, a wintry mix in the west, central, east, and northeast. Can’t get too fancy on where, it’s three days away. It will switch to snow Saturday evening/night; the EURO has it ending Saturday night with Sunday being dry. The GFS has the snow going in earnest Sunday morning with it ending by the evening. Have kept the chance for snow going in eastern KELOLAND for Sunday, 40% in Sioux Falls and 20% in Aberdeen.
Not too cold behind it either. Highs will be below average early next week in eastern KELOLAND, but a quick rebound is likely Tuesday with highs closer to average.
The extended models are showing a ridge trying to build into the upper plains by next Thursday. EURO keeps it around until the weekend (March 16-17), the GFS keeps the ridge around l o n g e r, until March (20).
