.DISCUSSION...

Currently there is an area of showers and thunderstorms moving
across southwest Virginia associated with a short-wave moving
across east Kentucky. This wave will keep likely chances going
across southwest Virginia and northeast Tennessee much of the
day. Otherwise, local terrain features will be the main forcing
mechanism similar to yesterday's convection.

MLCAPEs will increase to 2000-2400 later this afternoon with
DCAPE of 800-900 (Theta-e Difference of 25-30) and PWs of 1.6-1.8
inches. Mid- level lapse rates of 6-6.2 degree C. These parameters
support another round of active convection today with the main
threat being damaging winds (wet ground will again make down trees
a concern) and localized runoff/flash flooding problems.

As wave moves east this evening and loss of daytime heating,
convection will quickly diminish in coverage and intensity. Any
breaks in the clouds overnight will produce areas fog (some
dense).

&&

.AVIATION...
18Z TAF DISCUSSION.

Main flight concerns will remain mainly afternoon and evening
storms. Greatest coverage will be at/near TRI and TYS today due to
a short-wave moving across Kentucky/SW VA/and WV. These storms
will be mainly diurnal in nature and diminish quickly by/around
sunset.

Afterwards, next flight concerns will be the development of fog
and low clouds especially at TRI and TYS. IFR to possibly LIFR
conditions are possible especially between 06-12Z.

Redevelopment of storms are expected again Sunday but mainly
beyond the forecast period.

Due to surface ridging into the southern Appalachians, winds will
be light and variable except near storms.

This Hazardous Weather Outlook is for portions of southwest North
Carolina...east Tennessee and southwest Virginia.

.DAY ONE...This Afternoon and Tonight

Scattered showers and thunderstorms through this early this
evening then diminishing in coverage and intensity. Localized
flash flooding and damaging wind gusts are the main concerns
within the strongest storms.

.DAYS TWO THROUGH SEVEN...Sunday through Saturday

A wet pattern will remain in place with scattered showers and
thunderstorms each day. The greatest coverage of thunderstorms is

flooding will be possible with thunderstorms that move slowly or
track repeatedly over the same locations, and damaging wind gusts
will be possible with the strongest thunderstorms.

Be especially careful when camping due to the wet ground. The wet
soil increases the likelihood of down trees.
