The National Weather Service issued a Winter Weather Advisory for Loudoun County Christmas Eve that will continue until 8 p.m.

Snow began falling in Loudoun County about 1:30 p.m. and as of 3:45 p.m. was continuing to fall in the Leesburg area.

The National Weather Service is calling for accumulation of 1 to 2 inches, mainly across elevations above 500 feet.

Drivers should be cautions when traveling today. A Winter Weather Advisory means travel could be difficult with slippery roads and limited visibility.

The county is expected to be covered in fog by 10 a.m. Christmas Day.

A chance of sleet and snow is possible after 5 a.m. Wednesday with less than a tenth of an inch of accumulation, according to the National Weather Service.
