Storm Center Update-Wednesday AM

SIOUX FALLS, SD - After a very warm day Tuesday, the weather will be much cooler today with highs in the upper 40s to lower 50s and scattered showers in the south. Snow has even fallen in the Black Hills with snow covering portions of highway 16 near Custer.

Northeast winds will be common at 15-25mph today. There should be some sunshine in the northern part of KELOLAND today, but the south will likely stay mostly cloudy.

A major storm is going to start developing tonight and tomorrow with western KELOLAND feeling the first part of the system. Winter storm watches will go into effect late tomorrow for all areas west of the James River Valley. Temperatures will hover in the mid 30s for Rapid City, with around 42 in Pierre. Snow will most likely stay in the Black Hills region during the day, but spread east by evening.

Look for snow to mix with rain East River on Friday and some of the snow could be heavy near and west of James River, over 6”. There will be snow as far east as Sioux Falls on Friday and some accumulations are possible. Keep in mind it will be harder to accumulate snow during the day because of the sun angle this time of year.

Still, this is one to watch and will be very chilly with stronger winds from the east-northeast as the storm develops.
