.DISCUSSION...

An upper level low tracking to the north and east out of the
Lower Mississippi valley will bring widespread rainfall to the 
region over the next 3 to 4 days. This will lead to possible 
flooding for our area starting today, and continuing through 
Tuesday night, especially along the Blue Ridge where upslope 
flow will lead to higher rainfall totals. 

As the upper level low lifts north of the region on Thursday 
and Friday, more isolated to scattered showers and thunderstorms 
are expected both days. 

Given the widespread rainfall expected this week, there are 
minimal fire weather concerns at this time.
