KEY MESSAGES

- Northwest winds gusting 30 to 40 mph behind a cold front today. The combination of gusty winds and dry fuels lead to High Grassland Fire Danger over portions of central South Dakota today.

- Snow accumulations of an inch or less expected along and southwest of a line from Mobridge to Huron on Wednesday. However, locally higher snowfall amounts of 2 to 3+ inches could be possible within any narrow band or bands of snow that may develop. Southwest of Pierre, temperatures will remain warm enough to support rain or a mix of rain and snow.

DISCUSSION

Issued at 1129 AM CST Tue Feb 24 2026

The cold front continues to push south this morning with temperatures falling behind it across the northern counties including in Mobridge and Aberdeen. Radar returns have been running hot compared to sfc obs with dry mid levels and 7 to 15 degree dewpoint spreads to overcome. Sfc high pressure builds in across the east tonight into Wednesday morning.

That sfc high retreats northeast on Wednesday, but does potentially keep northeast SD and west central MN from seeing any precipitation with the waa band that develops tomorrow. As of 12z model runs, precip sets up southwest of a line from Mobridge to Huron Wednesday morning. Everywhere southwest of Pierre should remain warm enough to see rain or a rain/snow mix. Northeast of Pierre up to an inch of snow is forecast, but there are still "outliers" that indicate a heavier, narrow band of snow is possible with 3 to 4 inches of accumulation. May need to be staring at the white stuff falling from the sky at this point, though, before we can pinpoint where that sets up.

Drier and warmer conditions move in for the latter half of the work week before another cold front drops in Friday night into Saturday morning. Additional light snow is expected with this front on Saturday.
