This storm seems to have slid under the radar until now.  It appears a large amount of cold air will move into northern Virginia and Maryland tonight as precipitation moves into the area.  Rain will likely start this evening by 6PM and continue through 11PM when it will begin to mix with sleet and snow.  By midnight the precipitation will change over to all snow and continue through 5AM.  The snow may be heavy at times overnight falling at 1 to 2 inches per hour.  Leesburg can expect to see 5 to 6 inches of snow by sunrise Tuesday morning.  Areas to the north of Leesburg in Maryland and southern Pennsylvania will see snow fall for most of the night and may see 8 or more inches of snow.  Places south of Leesburg toward Warrenton, Culpeper, and Fredericksburg will see rain change to snow later which will keep snow totals on the lower side, receiving about 1 to 2 inches.

This is the current Watch/Warning map for northern Virginia.  Counties highlighted in pink are under a Winter Storm Warning until 7AM Tuesday where areas will see 4 to 8 inches of snow.  Counties colored in purple are under a Winter Weather Advisory until 7AM Tuesday where temperatures will be warmer and snow will not mix in until later.  These areas can expect to see 2 to 4 inches of snow.
