the region during the day Wednesday. The front will bring a chance
for rain and/or snow showers late Wednesday through Thursday
morning. A gusty and chilly northwest wind will develop behind the
front as a second area of high pressure builds to our northwest.
Temperatures will be about 5 to 10 degrees below normal Thursday.

This would put strong winds in the east and moderate to heavy snow
accumulations along and east of the Blue Ridge Mountains. We still

track and intensity could change quite a few times between now and
then.
