.DISCUSSION...

A low pressure clipper system will pass just north of the region
overnight with a trailing cold front crossing the area from the
west by early Thursday. This front will bring another round of
mountain snow showers including gusty winds later tonight into
Thursday morning. Weak high pressure will follow this system
resulting in lighter winds and a slow moderation in temperature
into the weekend. A weak system passing across the southeast
states may bring the next chance for rain showers by early next
week.
