Watches/Warnings/Advisories:
Winter Storm WATCH is in effect for Greenville & Spartanburg Counties from 7AM Friday until 7AM Saturday. A decision to upgrade to a Winter Weather Advisory or Winter Storm Warning should be made today.

Emergency Management continues to monitor the forecast for winter weather Friday into Saturday morning. As anticipated, the forecast has shifted some. The onset of the snow will occur between 11AM and 1PM Friday. The changeover from snow to sleet/freezing rain looks to occur around the Friday evening rush hour and continue into early Saturday morning. We'll have snow and then a layer of ice on top of it.

Below is the late afternoon briefing from our local National Weather Service Office.
