Sioux Falls, SD — A low pressure system is supposed to affect the Northern Plains this weekend. The warmer air spreading out ahead of the system is forecast to produce generally rainfall ahead of the system, which may end up as some freezing rain or a wintry mix with ice accumulation as precipitation develops north of Interstate 90 Friday night. People in northeast South Dakota into western Minnesota could experience freezing rain changing over to snow. However, we talked with National Weather Service meteorologist Billy Williams from the Weather Service Office in Sioux Falls, and he says our area probably won’t be affected by ice.
In fact, Williams says, depending on how this all plays out, we may not see much precip at all on Saturday night.
The Western Plains is expected to receive primarily snow, and the transition to snow will march eastward Saturday and Saturday night. North and west of our area, in western and central Nebraska, South Dakota, and northern Minnesota — they could receive several inches of snow accumulation.
