Storm Center Update - Wednesday AM

Northwest winds picked up again late yesterday and overnight, prompting the closure of I-29 from Watertown to Sisseton.
These northwest winds will be diminishing slowly through the morning, but areas of blowing snow will continue and many rural roads are experiencing heavy drifting once again.

Wind chills are running between -20 and -35 this morning and we have wind chill advisories in effect until noon for East River counties and until 11 a.m. for counties West River. Northwest winds will continue at 10-15 miles per hour in most areas.

Expect one more very cold night with lows below zero again for Sioux Falls and Aberdeen, but in the single digits above zero West River. The warming trend will start to gain some traction tomorrow with highs in the mid teens again in Sioux Falls, with 30s in the central and west.

That warming trend will really take off during the weekend with highs climbing back into the 30s and 40s East River, with 50s in the west. The west wind may be particularly strong on Saturday as well.

I don’t see any organized precipitation in the seven-day forecast other that some flurries possible in the east on Friday with mostly cloudy skies. It also appears very likely this mild weather will continue much of next week!
