DISCUSSION

Issued at 324 PM CST Thu Dec 18 2025

Conditions continue to improve from west to east this afternoon as winds slowly diminish and light snow continues to push off to the east into MN. Will be dropping headlines from west to east as we head into the evening hours as well. Still some pretty strong winds gusting from 50 to 65 mph, but those gusts will slowly subside from west to east as we approach sunset and shortly after. Will be dealing with some rather cold wind chills overnight across northern/northeast SD into west central MN, with readings from 15 below to perhaps as cold as 25 below zero.

Weak system moves across the Dakotas Friday into Friday evening. It appears most precip on Friday stays across ND according to various model reflectivity output, although there are some solutions that try to bring some light mixed precip across far northern SD, so have added low PoPs (20-30%) for this. Cannot rule out some light freezing rain across the region, but amounts look to have minimal impacts at this time.

Looking ahead towards the weekend into next week, don't see any major systems impacting the region and the forecast is mainly dry for the time being. Temperatures look to be near to above normal with no signs of any arctic air intrusions for the time being.

VFR conditions are forecast over the next 24 hours. Winds will continue to diminish through late this evening, particularly across northeast South Dakota and west central Minnesota. Should see a switch to southerly winds on Friday. Also, there is the potential for a few hours of low level wind shear to make its way across the region on Friday.
