.DISCUSSION...
An upper-level trough continues progress east across the region
this morning, spreading well-needed light to moderate showers
across the eastern Tennessee Valley and Southern Appalachians. As
this features approaches the region, the pressure gradient will
tighten and a 40-50 kt LLJ will rotate over the mountains between
18-00Z. This will result in strong/gusty downsloping winds over the
mountains through this evening. A wind advisory will continue for
this area and SW NC for winds gusting as high as 40-50 mph. These
winds may help to erode the precipitation shield over wildfire
areas and maintain or spread the flames in the drier areas. Clouds
and low stratus will hang on through the day with highs remaining
in the 40s. A chilly and damp day to say the least, but some
welcome rainfall with total amounts between 1/2 an inch in the
north and up to 2 inches in the south.
