At the onset of precipitation, a light wintry mix of snow and sleet will be possible, but precipitation will quickly turn over to moderate or at times heavy rain east of the Blue Ridge. West of the Blue Ridge for the Shenandoah Valley and Allegheny mountains, a wintry mix will hang on a bit longer, but precipitation should still change to rain by Tuesday afternoon and evening. A Winter Storm Watch is posted for the mountains in West Virginia mainly for the threat of freezing rain in the sheltered valleys.
