Storm Center Update - Friday PM

The weekend will start dry but end rather wet as we return to winter. Clouds will slowly increase from the southwest ahead of the storm system while temperatures fall to the teens and twenties. Parts of north central and northeast KELOLAND will fall to the single digits. We’ll have thicker clouds Saturday, but parts of KELOLAND will also have warmer temperatures. Highs will range from the lower forties in southeast KELOLAND to the middle twenties in northeast South Dakota.

Changes will start as early as Saturday night. Moisture will start to spread across the area with rain and freezing rain developing in southeast KELOLAND, but quickly change to snow around Highway 14 and north. Rain amounts can range from a half inch to an inch in southeast KELOLAND along with ice accumulations around a quarter inch. Snow amounts of six inches or more will also be possible along and north of Highway 14. IF thunderstorms develop in southern Iowa and Nebraska, it will take away from the moisture in KELOALND, thus allowing for light amounts of rain, snow, and ice. Once this system passes, temperatures will be much colder than what we had this past week. You can find more information below and through Tony Barlow’s video blog here.

Southeast KELOLAND…
After we enjoy temperatures in the lower forties on Saturday, things will change starting Saturday night. Rain and freezing rain will develop after midnight and continue into Sunday morning. Some areas will get ice accumulations of a quarter inch by late Sunday morning. There will be a sharp cut-off as to where the rain stops and the snow starts. As of now, Highway 14 looks to be that cut-off. North of 14, expect snow. South of 14, expect rain/freezing rain. Huron south to Mitchell and Wagner looks to be the cut-off on the west side of the system. East of this line will be rain/freezing rain, west of this line will get snow. The rain/freezing rain will eventually switch to snow by the afternoon. The best location for significant ice accumulation will be along Interstate 90 in southwest Minnesota to Mitchell and south (including Sioux Falls). Snow amounts of six inches or more will be possible where things fall as all snow, two to four inches of snow will be possible where things start as rain/freezing rain. Winds will slowly increase during the day on Sunday with gusts in the thirty mile per hour range at times. The combination of wind and snow will lead to reduced visibilities, use caution when traveling.

Central and Northeast KELOLAND…
Much of this area will get snow. The snow will start in south central and central late Saturday night and it will move into north central and northeast KELOLAND by sunrise. The snow will last through much of the day with amounts of six inches or more being common. Winds will be breezy with occasional gusts to thirty or thirty-five miles per hour. Be aware of dangerous driving conditions as the snow falls and the winds kick in.

Snow will start in western South Dakota Saturday night and last into Sunday. Snow in western South Dakota will also be heavy at times with amounts of six inches or more possible by Sunday evening. Winds in western South Dakota will get as high as thirty miles per hour at times on Sunday, leading to reduced visibilities. Use caution when traveling.
