Snow Lets Up; Heavier Again Later, Then Ice

Some could see total accumulations of 3-5"

Winter Storm Warning through 12 p.m. tomorrow for Loudoun and Montgomery counties and N & W

Winter Weather Advisory through 12 p.m. tomorrow for the rest of the metro area

Snow that began early this morning continues to fall, heavier south of town and lighter north of town. With every flake sticking, thanks to temperatures mainly steady in the upper 20s, many spots have seen their first inch of the seaon, with some already approaching 2 inches.

This Afternoon: We'll probably see the snow let up in intensity, possibly even break for a time, this afternoon as the storm's second wave gets organized off to our west. So additional accumulations through early evening may only be about 1" or less (possibly 1-2" south of D.C. where precipitation may be heavier).

This Evening: Once the storm's second wave arrives we're likely to see another burst of moderate to possibly heavy snow between 6 p.m. and midnight, which could accumulate an additional 2-3" across the region. Evening accumulation could be less or more depending on exactly when warmer air mixes in at the upper levels of the atmosphere and causes the snow to change to sleet and freezing rain -- which we believe will happen from southeast to northwest at some point this evening.

Late Tonight & Tomorrow: We still look to be on track for significant icing across the area, especially for D.C. and points north and west, before precipitation eventually changes to plain rain during the day tomorrow as temperatures warm to above freezing.
