Hazards: Light accumulating snow, sleet or freezing rain are likely, but amounts are still in question. When rain falls into the freezing air near the ground, it can flash-freeze on surfaces — that is freezing rain. The steadiest precipitation is likely during the morning hours, and it may be a mix of snow, sleet and freezing rain. The amounts are not high, but again — freezing rain is dangerous at any accumulation. Freezing rain is the most dangerous wintry weather.
