.DISCUSSION...
Key message 1: Dry conditions with a warming trend through
Saturday. Shower and thunderstorm chances return early next week.

Deep layer ridging over the southeastern CONUS will be in full
control of the sensible weather through Saturday as very warm air
aloft sets up shop, leading to plentiful sunshine. Max temperatures
are expected to be near normal this afternoon and nudging up a few
ticks Friday and Saturday with widespread mid to upper 80s outside
the mountains and major mountain valleys, with even a few spots
flirting with the 90 degree mark along and east of I-77. Dewpoints
are on the lower end making conditions feel pleasant for early June.

Temperatures remain in the mid to upper 80s through the
weekend and into Monday, while the ridging that will be in place
gradually breaks down in response to the ridge pushing back west.
Guidance has hinted at the early stages of an Omega Blocking pattern
developing late this weekend and the early part of next week. There
is also good consensus on a backdoor front moving across the CWFA
with a trough settling over the the northeastern CONUS. With the
frontal interaction, an increase in clouds and PoPs will allow
temperatures to trend a little cooler by the end of the forecast
period.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
At KCLT and elsewhere: VFR conditions will prevail through the
forecast period. SKC are expected through at least Friday morning
outside of the mountain tops. Mountain valley fog/low stratus is
expected, but confidence is low as to whether or not that reaches
KAVL, so didn`t place a mention in the 18Z TAF update. Winds are
mostly light and variable, which will remain this way through
daybreak Friday. Light southwest winds will develop by Friday
afternoon.

Outlook: Expect dry, VFR conditions to continue into the
weekend. The potential for morning mountain valley fog/low stratus
will gradually increase each day.
