Short term (tonight and sunday)...light scattered rain showers
will continue to move in to the area through the evening. A lot of
dry middle level air is present with rain having trouble reaching the
ground. Moisture will continue to increase in the middle levels as
the flow changes from southerly to southwesterly...and more
widespread rain showers will move in. Accumulations will be light
until after midnight.

Widespread showers are expected early morning through the evening
Sunday with around half an inch rain accumulation in valley and
plateau. Temperatures will be several degrees above normal through
the short term...with overcast skies keeping the temperature range small.

Long term (sunday night through saturday)...a river of moist air
will continue to feed into the southern appalachian region Sunday
night through early Wednesday morning. At least three short wave
features build across the middle south generating widespread light to
moderate showers through Tuesday afternoon followed by the frontal
push with the long wave upper level trough Tuesday night into
Wednesday. One to two inch rainfall is expected over most of the
forecast area although local amounts could reach three inches in
spots through Wednesday morning. The rain should taper off early on
Wednesday with a dry remainder of the forecast. The models still
hint at the possibility of light precipitation Thursday and/or
Friday with weak northern and southern stream energy shifting
across the eastern U.S. Just kept a slight chance of a sprinkle for
this possibility.
