DISCUSSION

Issued at 148 PM CDT Sat Mar 28 2026

NSSL-WRF was pretty spot-on in its wind depiction for the east today with 70 mph peak winds along the Coteau. Hwy 14 south overachieved with its mixing component as evidenced by most of the obs in Hand and Lyman county which are still gusting over 50 mph. Still expect winds to fairly quickly diminish from west to east this afternoon, especially after 21z when the western expansion of the wind advisory expires.

Latest 12z model runs of sfc dust continue to show an area of dust concentrating into parts of south central SD and east central SD tonight into Sunday. Winds will be fairly light on Sunday, so think hazy skies are the more likely outcome of what seems to be suspended dust moving up from the central plains and front range of the Rockies on the south side of the warm front tonight.

Another low moves into SD/NE on Monday. An upper low moving into MT/ND concurrently helps to suppress the ridge, but any associated precip remains north of this cwa. Current track of the sfc low keeps winds on the lighter side until Monday night/Tue morning when breezy northerly winds kick up behind the low with the cold front. The disjointed nature of the strongest winds/warmest temps/driest air may keep the region out of the worst of the fire weather concerns. Highs into the 60s and 70s through Monday fall back into the 40s for Tuesday through Saturday. There are no strong signals for widespread precipitation over the next week.
