.DISCUSSION...
Key message 1: Dry and hot conditions today and Sunday. Shower and
thunderstorm chances return early next week.

Deep layer ridging builds over the southeastern CONUS into the Great
Lakes through Sunday. Periods of cirrus spread over the area today
and Sunday, along with some fair weather cumulus. Highs will be
above normal, with highs around 90 over the I-77 corridor. Dewpoints
will be higher today, but still in the comfortable range, especially
for early June. They do creep back into the 60s on Sunday bringing
more humid conditions but not quite into the muggy range.

A narrow but deep trough will move into the eastern CONUS Monday
through Wednesday breaking down the ridge. Weaker shortwaves cross
the area Thursday and Friday. A backdoor cold front drops into the
area Monday and stalls over the area Tuesday. A weak cold air
damming high sets up by Tuesday with temps near to a few degrees
below normal. This also brings a return of mainly diurnal
convection. The front washes out and the high moves into the
Atlantic with a moist southerly flow developing. This brings a
warming trend with highs in the 90s Thursday and Friday. Mainly
diurnal convection continues each day.

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: Dry, VFR conditions will continue at the
TAF sites through the period. That said, there will be early morning
mountain valley fog that will be near but not at KAVL. Cirrus,
occasionally thick, will spread across the area through the period.
Some high based Cu expected during the afternoon. Light SW to light
and variable wind this morning picks up speed from the SW during the
day, becoming light during the evening. Another round of mountain
valley fog near but not at KAVL overnight.

Outlook: Expect dry, VFR conditions Sunday, although the potential
for morning mountain valley fog/low stratus will continue. Diurnal
convection returns Monday continuing through the middle of the week.
