We're in Day 4 of our April storm. Overnight, snow moved into the eastern counties and dropped more than six inches of fresh powder. There are many trees down and the weight of that new snow is sagging power lines. The good news to salvage: winds are not powerful, yet (Marshall, MN being one exception).
There is still a Winter Storm Warning in effect until 1 p.m. this afternoon. We'll break down your forecast by region, since so much is going on.
Several pieces of this April storm have come through this area. One of the final chunks is the heavy snow aided by an upper-level low. This is the cold side of the storm. We're tracking this northern part as it pivots back towards Brookings, Huron and Watertown. That means the counties north of Sioux Falls will see sustained snowfall later into the morning. When I measured snow in Sioux Falls before the 5:00 a.m. hour, we had between 5.5-7".
The system will slowly make its way northeast, but light snow could linger through this evening. Tomorrow should be dry but cloudy but we're still in an active period. Another system comes in this weekend and that brings a chance of rain. There are more chances of moisture by the middle of next week.
The storm is rotating and is pushing back to the WEST. That means prolonged snowfall, on top of already heavy totals in the Aberdeen area. While the rest of the storm is closing in on the East Coast, the northern part is not moving much. Lighter snow could last through tonight and parts of tomorrow in our far northeastern counties. Clouds will remain in place and the wind is likely to pick up tomorrow and Saturday. We're tracking this weekend system for a chance of wintry mix on Sunday. There isn't much of a spring-like feel in the 7-day forecast. There are more chances of moisture into next week.
Central and West:
More than two feet of wet and heavy snow continue to sit on the prairie and in the Hills. This is a big deal for ranchers during calving season. Winds were not a major issue overnight. The winds will pick back up later this evening into tomorrow. Calmer but cloudy air is sticking around for today but most will remain dry. Tomorrow more moisture arrives, with scattered showers (of a wintry mix).
With warmer air arriving this weekend, that chance turns into rain. Scattered chances of mix remain in the 7-day and there is a chance of more moisture each of the next few days.
