.DISCUSSION...A system passing through the region will allow for 
isolated to scattered showers across the south today. This low 
will lift northeast and weaken by Wednesday, providing for daily 
isolated to scattered shower activity each day with embedded 
thunderstorms possible. Chance of wetting rain is low. A deeper 
and colder storm system looks to drop in late Thursday through 
Friday and Saturday, bringing potential for mountain snow.
