- There is a 30 to 60 percent chance of light rain this morning mainly north of U.S. highway 12. Little to no precipitation is expected.
- There is a 30 to 50 percent chance of light rain and snow Thursday, with little to no accumulation expected.

UPDATE
Issued at 825 AM CDT Wed Apr 8 2026
No notable changes planned to the today period forecast. Watching a mid-level (WAA zone) forced band of precipitation, associated with the upper low over south central Canada, trying to hold together over north central South Dakota. Cloud bases are registering at or above 10kft for the most part, so hard to believe much more than sprinkles (if anything) are reaching the ground out there. Despite there being some weak low level CAA behind the passage of an occluded/cold front today, the going temperature forecast may still be in the ballpark. Just about the only concern right now, moving forward, is whether or not the Wind Advisory will need to be expanded further east into Minnesota from this afternoon into early this evening. Monitoring trends in guidance for now.
DISCUSSION
Issued at 1258 AM CDT Wed Apr 8 2026
As of 1 AM CDT, we have some rain showers moving into north central SD. These showers are expected to move east across the area through the morning hours. Accumulations of less than a tenth of an inch are expected. Temperatures across the area are in the mid to upper 30s with winds out of the south to southeast at 15 to 20 mph, gusting up to 30 mph.
A low pressure system will move across the area today and bring our winds around to be out of the north to northwest. Strong winds will continue into the early evening hours, gusting 35 to 50 mph, highest over north central SD where a Wind Advisory will be in effect from 10 AM CDT until 7 PM CDT. Temperatures today will be closer to normal with highs in the upper 40s to upper 50s, warmest across south central SD. These warmer temperatures and stronger winds will create enhanced grassland fire danger across south central SD. Short term fuels are starting to green up and there has been a good bit of moisture in the area but the strong winds will be the main concern. Winds will begin to die down this evening. The next chance for precipitation will be Thursday. This is expected to be mainly light snow, changing over to rain during the later afternoon hours south of Hwy 14. Snow accumulations are expected to be a couple tenths at most, and melt quickly. WAA showers move in Saturday along with some gusty winds of 30 to 35 mph as we move from high to low pressure. Precipitation chances continue into Sunday and Monday as another low pressure system moves across the area. Chances for more than a half an inch in 48 hours (ending Tuesday morning) have come down significantly to around 20-30%. Much cooler air moves in behind the low as high pressure makes its way south out of Canada, dropping lows overnight Monday potentially into the mid 20s and highs Tuesday struggle to recover, potentially only reaching the low to mid 40s. This may result in some light snow showers Tuesday. Little to no accumulation is expected at this time.

A front continues to sweep east across the area this morning. Right in the axis, winds have gone calm as they shift to the northwest. Northwest winds then increase behind the front again with gusts of 30 to 37kts expected today. VFR conditions will prevail through the day, though there is some patchy IFR stratus floating around that models have struggled with near KATY.
