It won't be that warm (in some areas) despite the southeast wind. Highs today should stretch towards 30 in Sioux Falls, which is below normal. In Rapid City, however, we could easily hit 50. Winds will be felt, easily gusting above 25 mph.
For this evening, a Clipper system mostly impacts North Dakota. But snow will build both into the northern Hills and the farthest northern counties. Though accumulations will be light, I do see visibility concerns fo those driving late tonight and into tomorrow morning. Winds won't really die down in this area tonight, so watch out for that. Flurries could comes farther south, but it won't be widespread. This should head east by tomorrow afternoon.
Tomorrow should be quite a bit warmer. Snow will continue to melt off as highs climb above freezing. Southeast winds remain up in the east, and stay strong from the northwest in the Hills. Monday does bring colder temperature again.
One feature we haven't seen much of this winter is Gulf moisture access. It will boost the Tuesday system. Watch for it to slow down as soon as it heads our way from the Rockies. The low looks tightly bound for now with the POTENTIAL for pretty rough conditions, especially in NE KELOLAND. This would be day 4 on your 7-day forecast, so it's still quite a bit away.
Winds pick up today ahead of a new tracking mainly north of us tomorrow. The following (and stronger) system is following for Monday night - Wednesday morning.
