.Near Term [Through Tonight]...

Abundant tropical moisture remains in place across the forecast area
this afternoon. While the rain has not been widespread, it has been
locally heavy with up to 5 inches falling in a corridor from Camilla
to Albany this morning. Through tonight, a weak shortwave will cross
the region and begin to push the deeper moisture south and east of
the forecast area. This should lead to diminishing rain chances as
the night goes on. Until that time, there is still some risk for
isolated heavy rain, so will allow the Flash Flood Watch to continue
until 00Z this evening.

.Short Term [Tuesday Through Wednesday Night]...

After the main area of rainfall out ahead of the weakening shortwave
just off to our west gradually winds down tonight, PoPs will be
significantly reduced for both Tuesday and Wednesday, as weak upper
level ridging begins to become established over the northern Gulf
Coast. However, with PWATs still expected to remain unusually high
for this time of year, especially further to the south and east
across the CWA, isolated to scattered showers and storms will be
possible each day, especially over our FL zones. PoPs will range
from silent 10s over most of SE AL and SW and SC GA, to 20 to 30%
over most of N FL. The lone exception will be the extreme SE Big
Bend (Dixie county), where 40% chances are still expected. With the
lower PoPs, upper ridging, and more daytime insolation, a gradual
warming trend is expected during the next couple of days, with
widespread high temps in the middle 80s on Tuesday, and upper 80s to
around 90 on Wednesday. Lows on Tuesday night will be in the middle
to upper 60s.

.Long Term [Thursday Through Monday]...

Very little has changed with regards to the extended fcst, as the
period will begin with very warm and humid conditions on Thursday
and Friday, as weak upper level ridging will nose northward from the
Gulf of Mexico. Along with the well above climo temps and dewpoints
will be increasing chances for showers and thunderstorms. This
activity will precede the strongest cold front of the season thus
far, with good agreement among the Global Models that it will pass
through the CWA on Friday night and Saturday morning. This cold front
is still expected to bring a true taste of fall weather to the
region for the upcoming weekend into at least early next week. Low
temps on Sunday and Monday mornings will at least drop into the
lower to middle 50s over much of the interior, with the ECMWF MOS
now indicating the possibility of some lows dipping into the 40s
across the northern portion of the Tri-State area. With plenty of
daytime insolation, however, high temps are only expected to be a
few degrees below climo at this time for the end of the period, with
maximum afternoon readings generally in the upper 70s to the lower



[through 18Z Tuesday] MVFR conditions occurring at most terminals
early this afternoon. Main exception is KECP which still has IFR
cigs. Expect MVFR to occasional IFR conditions to continue through
the afternoon before IFR cigs settle in at all terminals this
evening for the overnight hours. Conditions will be slow to improve
on Tuesday, with MVFR conditions not expected until late morning.



Once the remaining widespread convection exits our Coastal Waters
tonight, the resulting very weak surface pressure pattern will keep
winds and seas quite low through Thursday night. By Friday, winds
and seas will increase out of the southwest in advance of the next
cold front, with near cautionary conditions possible out of the
northwest behind this front on Friday night into Saturday.

Hazardous fire weather conditions are not expected over the next few



With the rainfall event now winding down, and only very isolated
pockets of heavy rainfall having been observed over the past couple
of days, no significant rises are expected on our area rivers and
