A lot going on over the next several days as KELOLAND returns to winter conditions.
Things start tonight with areas of rain and snow in the Black Hills of western South Dakota. There are Winter Storm Warnings for the southern Hills tonight through Tuesday morning. This is where six to twelve inches of snow will be possible by Tuesday. Winter Weather Advisories are out for the plains of western South Dakota as strong winds will combine with snow to create reduced visibilities. North to northwest winds of twenty-five to fifty miles per hour will be common with higher gusts. Use caution when outdoors in western KELOLAND tonight through Monday night. While snow amounts for the plains of western South Dakota will be around one to three inches, south central KELOLAND will have higher amounts of three to six.
The light rain in central and eastern KELOLAND tonight with continue into Monday morning before switching to snow late in the afternoon and evening. As the storm system moves through KELOLAND, light snow will continue Monday night into Tuesday. Snow amounts in eastern KELOLAND (from near the James River Valley and east) will average one to three inches by Tuesday afternoon. Amounts west of the James River will also average one to three, but there will be isolated spots with higher amounts such as from Pierre to Chamberlain. Winds will not be as strong in central and eastern KELOLAND, but speeds of fifteen to thirty miles per hour are likely. So, blowing snow and reduced visibilities will also be a problem Monday night into Tuesday for eastern KELOLAND. Use caution when outdoors later Monday afternoon through Tuesday.
Christmas Eve (Wednesday) will be dry, but we’re watching for the next snow maker on Christmas Day (Thursday). The best chance for the snow on Thursday is in western South Dakota. I’ve upped the chance for snow in Rapid City to fifty percent. The snow chance for central South Dakota and southeast KELOLAND is at thirty percent; while northern and northeast South Dakota will be dry. It’s too early to pinpoint snow amounts, but the heaviest will be in western South Dakota during that time while the central and east might be able to squeeze out an inch or two.
After the snow later in the week, much colder air will pour in with highs only in the teens for the weekend.
