First Round of Winter Weather Continues

Precipitation Timing and Type

Snowfall amounts through Thursday

Ice Accumulations through Thursday

A Winter Weather Advisory continues for the first round of wintry precipitation through Thursday. Snow with wintry mix/freezing rain will continue through the afternoon into the evening before transitioning back to snow tonight as temperatures cool. This is all highly dependent on how fast the temperatures change. Gusty easterly winds may lead to patchy blowing snow and drifting which would cause slight visibility reductions, but whiteout conditions are unlikely.

With warmer temperatures, the precipitation will be a wintry mix/freezing rain this afternoon into the evening before the temperatures cool and the precipitation transitions back to rain. East central SD is the most likely area to see a light glaze to a tenth of an inch of ice from freezing rain. There will then be a break in precipitation Thursday afternoon into the evening before the second round of precipitation starts.

The first round of snow will continue through tonight into Thursday. There will be some wintry mix of precipitation as temperatures warm this afternoon into the evening before changing back to snow. 2 to 5 inches are still expected north of Highway 212 (highest over the Leola Hills and eastern slopes of the Sisseton Hills) with a trace to 2 inches south of Highway 212. There are still a few unknown factors still remain which continues to lead to some uncertainty in these amounts.

The first round of wintry precipitation moving into the area has the possibility of light freezing rain, with east-central sections of South Dakota have the best chance to see this freezing rain into tonight. A light glaze up to 0.1 inch of ice accumulation will be possible in these areas by late tonight into Thursday. This could make roads slick and impact the Thursday morning commute.
