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.

An increase in MVFR/IFR CIGs is still in the forecast through Tuesday morning, along with increasing areal coverage of FG/BR and IFR/MVFR VSBY. Confidence on arrival time at the TAF sites, along with overall coverage is somewhat low at this time. Conditions are forecast to improve across central SD (KPIR/KMBG) by late morning or closer to 18Z, while areas further east (KATY/KABR) may be stuck with clouds and fog later into the afternoon. Suggestions point to more FG/BR Tuesday night.
