A Mild Start to the Work Week
Sharply Colder by Wednesday
SIOUX FALLS, S.D. (Dakota News Now) -- Aside from a breezy northwest wind and a few isolated drizzly showers and flurries, it was an overall nice Sunday with temperatures in the 30s and 40s. We’ll look to keep that around to begin the week, but another blast of cold air moves in by midweek.
TONIGHT: Skies will remain partly to mostly cloudy areawide, but areas west of the James River will have clearer skies for most of the night before clouds move in overnight. Winds will decrease from 10-25 mph to 5-10 mph and begin to shift from the NW to the W and SW overnight. If the winds can calm enough, patchy fog could develop, especially in the areas that saw melting snow. Lows drop back into the teens and 20s.
MONDAY: Some patchy fog could be possible during the morning hours, otherwise we’ll see a decrease in clouds throughout the day and is expected to become partly cloudy to mostly sunny in the afternoon. Winds will be out of the S to W at 5-15 mph. Highs will be in the 30s and 40s with lows in the teens and 20s.
TUESDAY: We’ll have a partly cloudy sky throughout the day, but the story will be a strong cold front that’s expected to move through during the day into Tuesday evening, bringing with it another shot of arctic air heading into midweek. Winds will also become strong as the front passes through, with a SW wind shifting to the NW and increasing from 5-15 mph to 20-35 mph with gusts to 50 mph expected. WIND ALERTS could very well be needed, especially along and west of the James River. Highs will be in the 30s and 40s both days, but expect temperatures to drop late in the day into Tuesday night. Lows will range from -10 to 5 above Tuesday night.
WEDNESDAY AND THURSDAY: It’ll be sunny and very cold Wednesday and Thursday with highs in the single digits and teens. The coldest air will be along and east of the James River and I-29. Lows overnight will be in the single digits and teens below with some readings dipping into the 20s below. WIND CHILL ALERTS could very well be needed during this time.
NEXT WEEKEND AND BEYOND: The next chance of precipitation returns Friday in the form of some light snow and a wintry mix. Models continue show a chance for some light snow and flurries at times over the weekend into the early parts of the following week, but as always we’ll watch models trend throughout the week. The other story we’ll be monitoring is temperatures as models diverge greatly on that. Some have highs near to above average while others show another round of very cold air moving in, especially towards the middle parts of the following week. For now, I’ll keep temperatures near seasonal averages, but know this is expected to change.
