.DISCUSSION...

KEY MESSAGE 1...Significant heat returns Wednesday through the
weekend, however we look to stay below heat advisory or warning
criteria.

Large scale upper ridge of high pressure builds into the area from
the NW today. This will push the enhanced moisture axis south of the
area and the switch to a dry subsident airmass will allow for mostly
clear conditions through Thursday. Some suspended smoke further
north could makes its way into the area by tomorrow which could
result in some haze. Temps will moderate warmer going into
midweek with Wednesday through Friday having the highest max
temps of the forecast period. The temps combined with some
increased dewpoints could result in heat indices near the low
100s for parts of the Piedmont during this period and possibly
near the 105 deg advisory level in the east on Thursday. Please
monitor future updates to the forecast.

KEY MESSAGE 2...Scattered daily afternoon and evening showers and
thunderstorms return for Friday into the weekend.

The aforementioned ridge dampens and breaks down by Friday allowing
for a return of moisture advecting in from the west and increased
chances for diurnally driven convection. Coverage of showers and
storms should increase for Saturday as an amplified shortwave trough
digs into the area. On the heels of this feature, a frontal boundary
is progged to track SEWD for Sunday and again allow for increased
coverage of convection. While still pretty far out to properly
assess severe potential, for now shear parameters are not impressive
though low level lapse rates could be quite high so some stronger
convection could have enhanced downdraft winds each day.

.AVIATION /15Z TUESDAY THROUGH SATURDAY/...
VFR conditions for most sites through the period (other than
typical morning fog for LWB. Some daytime FEW/SCT cu field
today near 3-5 kft then mostly clear tonight and possibly some
haze for Wednesday with suspended smoke that could work its way
southward. Winds today generally out of the east 5 mph or less
becoming mostly calm overnight (maybe light SW for LYH), then
Wednesday could be light west to north and even light VRB for
some sites.

EXTENDED AVIATION OUTLOOK... Diurnal showers and thunderstorms
are expected to return Friday through Monday, bringing some
gusty winds and heavy rainfall as well as periods of MVFR or
lower conditions. Mountain valley fog/low stratus will also be
possible each morning.

Winds will be variable in direction Wednesday through Friday. A
west wind with speeds between 6 and 12 kts develops Saturday
and Sunday, with gusts to 20 kts or so.
