SIOUX FALLS, S.D. (KELO) — A strong early spring storm is striking KELOLAND today.

We have a little bit of everything with this storm.

Snowfall rates were at 2 inches an hour for some areas in western South Dakota Friday morning.

Downtown Rapid City already had 4 inches of snow as of 9 a.m. As of 4:30 p.m., the city reportedly had at least 9 inches. The heavy snow has been spreading across South Dakota throughout the day.

While the snow is already falling out west, the northeast experienced freezing rain Friday morning and the southeast had thunderstorms throughout the night.

While Sioux Falls is not in the blizzard warning, winds over 50 miles per hour are expected this evening so blowing snow will be a problem.

Winter Weather Alerts

Several weather headlines have been posted for Friday, including the ice storm warning in the Watertown and Milbank areas until 4 p.m. Power outages are expected throughout the day as the winds increase.

The ice will be a problem outside the warning area toward Huron and points southwest. Some areas can expect over 1/4″ of ice today.

A blizzard warning starts this morning for central SD for the counties shaded white, with those headlines expanding east of the James Valley late this afternoon into the evening.

Sioux Falls will be included in a winter weather advisory for this evening for blowing snow.

Snowfall totals

How much snow to expect depends on where you live.

The highest snowfall amount forecasted is in central KELOLAND. Pierre and Chamberlain fall in the 8-12 inch range.

Aberdeen, Watertown, Huron, Phillip, Rapid City, Custer and Pine Ridge are forecasted to have 4-8 inches of snowfall during this storm.

Winner residents should be prepared for 6-10 inches.

In Sioux Falls, only 1-2 inches of snowfall is forecasted, but again blowing snow will still be an issue.

Emergency crews in the city are focusing their efforts on emergency routes, hills, schools, main lines and working into the residential areas, officials said Friday morning.
