SHORT TERM /TODAY THROUGH SUNDAY AFTERNOON/

Issued at 334 AM CST Sat Jan 24 2026

Surface high pressure will continue to slide southeast this morning. As it does, winds will pick up marginally behind it, just enough to make wind chills meet advisory criteria. Currently most obs are hovering between -25 and -30 with slightly colder readings at the RAWS sites. Expanded the Cold Advisory to the remainder of the counties in central SD.

An upper trough digs in this afternoon with a lobe of shortwave energy and some mid level moisture. Expect these features to generate some light snow showers and flurries across the area this evening through Sunday morning. Up to half an inch of snow is possible. NBM, per usual, is washing out this light precip, but ConsShort and ECAM both had reasonable pops and QPF so leaned that way in the grids. A 1040s high then builds in Sunday afternoon shutting off any ongoing flurries even with the potent shortwave trough aloft.

Will let the day shift take another look at any necessary headlines for tonight into Sunday morning. It's possible that the northern tier could hit -30 again, but clouds could be a mitigating factor.

LONG TERM /SUNDAY EVENING THROUGH FRIDAY/

Issued at 334 AM CST Sat Jan 24 2026

The long term opens Sunday night with an upper level trough making its way north to south across SD.This is south and out of the region by sunrise Monday. High pressure is in place at the surface during this time that will move south. A warm front moves across the surface during the day Monday bringing westerly winds and some WAA to the forecast area. This will usher in some slightly warmer temperatures, although still 10-15 degrees below average. The rest of the work week features high pressure at the surface and dry conditions with the exception of Wednesday when models show a slight chance for some snow between the MO and James Rivers. Chances are 20% or less. As mentioned, temperatures during the period are expected to still be below average. Highs are generally in the teens to 20s, slightly higher in south central SD. Temperatures look to start a warming trend into the weekend and beyond. Not much expected in the way of winds during the period, although signal continues for some higher wind gusts on the eastern side of the Prairie Coteau Monday afternoon as the wind takes on a more southwesterly direction.
