A Look Ahead
As a weak low and stationary front sets up across the Southern Plains and into the Midwest, temperatures near or below freezing are forecast to the north of the front. With Gulf moisture from the south moving into the region and bringing warmer air aloft, there is a threat for a significant ice storm over the region. Model guidance continues to remain consistent in the forecast of temperatures at or slightly below freezing leading to freezing rain and/or sleet due to the warm air aloft. This front is forecast to remain over the region for much of Saturday. The potential for sleet and freezing rain is expected to extend further into the Midwest as the system becomes more established with precipitation continuing in some form of ice over the Southern Plains. As a result, continued significant winter weather will be possible from the Southern Plains and into the Midwest in locations to the north of the stationary front and where surface temperatures fall below freezing. Into Sunday, the upper level pattern will begin to change and shift the area of low pressure and subsequent stationary front out of the Southern Plains and to the east-northeast. Significant winter weather including freezing rain and/or sleet will shift northward ahead of the freezing line ahead of the warm front into Sunday.

As a low tracks into the Central Plains on Monday, the winter weather potential will shift into the Central and Northern Plains. Freezing rain, sleet, and snow will all be possible.
