.DISCUSSION... 
Cold but dry weather conditions are expected to continue through 
Sunday as high pressure moves across the Mid-Atlantic. Another 
storm system will move across the region Sunday night through 
Monday, and could bring some light rain and snow to the region. 
The mountains will have the best chance to receive some 
accumulating snow from this system, with an inch or two possible 
west of the Blue Ridge Monday. Another storm system could 
impact the region in the middle and latter parts of the week.
