SIOUX FALLS, S.D. - A winter storm warning for snow and ice will be in effect from 3 a.m. Sunday to 6 a.m. Monday for Nobles, Jackson, Rock, Pipestone, Murray and Cottonwood counties in Minnesota and Lyon County in Iowa.
The winter storm watch is no longer in effect.
Timing: Freezing rain and snow will develop early Sunday morning and continue throughout the day before diminishing Monday morning. The freezing rain will mainly be confined to areas along and south of Interstate 90, mixing with and changing over to snow by Sunday afternoon.
Accumulations: A tight gradient of both snowfall and ice accumulations is expected across the area. Snowfall will vary from near 2 inches south of I-90 to near 10 inches near Mitchell. Where the snowfall is less, there will be an increased threat for ice where up to a quarter of an inch of ice is expected.
Wind and Visibility: Winds will increase to 20 to 35 miles per hour on Sunday into Sunday night, producing blowing snow and reducing visibility below half a mile in open areas. In addition, some power line stress may occur in extreme southeast South Dakota and far northwest Iowa as ice accumulations approach a quarter of an inch.
Precautions: A winter storm warning means significant amounts of snow, sleet and ice are expected. Strong winds are also possible. Travel will be very hazardous or impossible.
