Precipitation continues to move north into eastern and southeast KELOLAND. The main part of the storm system has moved slightly east than previous model runs had it. This means, the snow will not cover as large of an area in eastern KELOLAND.
Numerous advisories and warnings have been dropped in eastern South Dakota than what was out previously this morning. But Winter Storm Warnings are still out in southeast South Dakota as well as southwest Minnesota. Counties in northwest Iowa have been added in the Winter Storm Warning due to the storm system being a little farther to the east.
Temperatures have remained in the middle thirties this afternoon, so much of what falls during the afternoon should come down in the form of rain. As temps cool, rain will mix and change to all snow by 5:00. Be alert for changing weather conditions for the late afternoon/early evening commute. The snow will be heavy at times during the evening causing reduced visibilities along with quick slushy accumulations likely.
Snow will continue through the evening and overnight with the highest totals in southwest Minnesota where six to ten inches can accumulate in and near Marshall. Four to eight will be possible from south of Brookings to Sioux Falls and into northwest Iowa. Snow will not be as heavy north and west of Brookings. As the storm system continues to move northeast, the snow will come to an end late tonight into Friday. Even though the storm system will be leaving our area, north winds will increase to cause areas of blowing snow and reduced visibilities. Use caution when out and about this evening and tonight.
Lingering snow will be possible in extreme eastern KELOLAND Friday morning, but it will quickly move out of the area. North winds will slowly calm as we go through the morning and into the afternoon and clouds will slowly decrease. Central and western South Dakota will see the sun sooner, but temperatures will remain below average for all of KELOLAND. Expect highs in the thirties and forties.
The weekend is looking warmer with highs in the forties and fifties. This will happen with dry skies on Saturday, but scattered rain showers will be possible on Sunday. Temperatures will continue to slowly warm as we go into next week with sixties looking likely on Wednesday.
