UPDATE

Issued at 1136 AM CST Tue Mar 3 2026

Dense fog is quickly mixing out/ending. Another round of patchy fog is forecast for tonight. Snow is quickly melting with temperatures in the 30s and 40s and dewpoints mainly in the 30s, adding to the low level moisture.

DISCUSSION

Issued at 105 AM CST Tue Mar 3 2026

As of 1 AM CST, temperatures are in the upper 20s to low 30s under relatively clear skies and winds are out of the south at 10 to 15 mph. Some areas of fog/freezing fog have formed between the Missouri and James Valleys this morning. This could cause slick roads for the morning commute.

Quiet weather continues today with mild temperatures expected. Going with the trend of the last few days, did lower high temperatures again today both for snowpack and cloud cover. Looking ahead to the Thursday night/Friday system, not too much has changed location wise. PoPs have increased into the 40-60% range across most of the CWA. With uncertainty of strength and temperatures for this event, precipitation types/locations are uncertain but there does look to be potential for freezing rain with this system. For now, the chance of freezing rain has increased over eastern SD to 15-30%, highest over the Prairie Coteau/Sisseton Hills area. The chance for 1 inch or more of snow has also increased, now between 30 and 60%, highest over south central SD where QPF amounts are higher. Temperatures behind this system look to rebound relatively quickly as we get some strong WAA in from the west.
