DISCUSSION

Issued at 100 AM CDT Mon Apr 6 2026

As of 1 AM CDT, temperatures around the area are in the 30s with winds out of the northwest between 10 and 15 mph. Some light snow showers will move into central SD this morning. There is the potential for this to end up as rain if temperatures don't cool as much as expected. Little to no accumulation out of this. If anything does accumulate it will melt quickly.

We're under a pretty cool airmass today which will keep our highs 15 to 20 degrees below normal for this time of year. Fortunately, high pressure moves in later today and brings our winds around to out of the south. This will bring much warmer air up into the region and bring temperatures up to around normal by Wednesday. Tuesday and Wednesday will be a bit windy with gusts of 30 to 45 mph ahead of and behind a low pressure system. The strongest winds, gusting near 45 mph, will be Wednesday across north central SD. This system will also bring a 30-60% chance of rain to the region, highest across northern SD late Tuesday night into early Wednesday morning. The chance of more than a tenth of an inch in 24 hours is still 15% or less. This event does look to stay predominantly rain, but there is a chance some snow could mix in for an hour or two in the Missouri River valley overnight Tuesday. We get a little bit of a break Thursday before 30-40% chances return and remain in place through the weekend. The period of heaviest rainfall looks to be Sunday night into Monday morning. The chance for more than a quarter of an inch in 24 hours (ending Monday morning) is between 30 and 50%, highest over eastern SD. Temperatures for the weekend look to be about 10 to 15 degrees above average.

Two scattered areas of MVFR stratus are affecting the region this morning, one east of the James Valley that's moving over KATY and one that is just to the north of KMBG. There has been little model consistency with the cigs across central SD, but did bring some MVFR cigs into KPIR as the band of light snow nears this morning. After 18z, VFR conditions are expected to prevail.
