Precipitation will develop along and ahead of the front. Behind the front, snow and freezing rain are expected. At this time, exact amounts and timing are not available due to forecast uncertainty. However, interests from Oklahoma northeastward into New England need to remain aware of this developing system and the potential for accumulating ice and snow in the region.
