Area Forecast Discussion
National Weather Service Tallahassee FL
345 PM EDT Tue Sep 4 2018

...TROPICAL STORM GORDON CONTINUES TO IMPACT MAINLY THE GULF
COASTAL WATERS WITH LOCALLY HEAVY RAIN ALONG THE COAST...

.NEAR TERM [Through Tonight]...

Tropical Storm Gordon continues to track northwest toward the
AL/MS/LA coastlines. Movement has slowed slightly to 15 mph. Gordon
appears more organized this afternoon. Feeder bands on the southeast
side of the circulation may rotate into the region this afternoon or
evening. Gordon is forecast to continue strengthening to a Cat 1
hurricane before landfall near the MS Coast.

Tropical Storm warnings are in effect for parts of the coastal
waters. Tropical storm force winds will remain offshore. For inland
and coastal areas tropical storm force winds are not expected.
However, convective feeder bands moving onshore can produce strong or
even severe winds locally. SPC has Big Bend Florida west of
Tallahassee in a marginal risk for severe storms. Most of the
Panhandle Coast is in a slight risk for severe storms.

Scattered thunderstorms are developing over North Florida and South
Central Georgia. Thunderstorm activity will increase this afternoon
and evening as easterly flow moves storms westward into the region.
Feeder bands are also moving in from the south. Overnight
thunderstorms and rain will be more confined mainly west of a line
from Tallahassee to Dothan as Gordon moves away from the region.
Overnight expect cloudy skies with lows in the lower 70s.

.SHORT TERM [Wednesday Through Thursday Night]...

By Wednesday morning, Gordon will be weakening from a tropical storm
to depression status somewhere over southern Mississippi and
tracking northwestward further away from the forecast area. Deep
layer ridging northeast of the forecast area over the Mid Atlantic
stated will place the forecast area in a region of deep-layer
easterly flow. A tropical upper tropospheric trough (TUTT) will
approach Florida on Thursday and be over the peninsula by Friday
morning. PoPs on Wednesday will still be influenced by the proximity
of Gordon with likely PoPs over Walton County tapering to 20-30
percent across our eastern time zone counties which will be closer
to the ridging. On Thursday, the pattern reverses as higher PoPs in
the 40-50% range will be over our eastern zones closer to the TUTT
with 20-30 PoPs further west. Overnight temperatures will be a few
degrees above normal during this period with daytime highs
close to normal around 90.

.LONG TERM [Friday Through Tuesday]...

The TUTT will gradually weaken as it moves west across the Gulf of
Mexico during this period. Its presence and contributions from the
east-coast sea breeze will enhance PoPs across our eastern zones
once again on Friday. From the weekend through early next week, we
will settle into a fairly typical summertime pattern with scattered
thunderstorms developing on the sea breeze and outflow boundaries
each day. Temperatures will be seasonally warm.

&&

.AVIATION [Through 18Z Wednesday]...

All terminals have returned to VFR conditions as of early this
afternoon. However, there will be periods of MVFR/IFR cigs/vsbys
in convection associated with the outer rain bands from TS Gordon.
Also, winds will gust at times in the 15-25 kt range with the
highest gusts at ECP. Expect MVFR/IFR ceilings and possibly vsbys
to gradually return by this evening and linger at least through
13-15z Wednesday.

&&

.MARINE...

Tropical storm warnings will remain in place across parts of the
coastal waters into tonight, mainly for gusts. All marine headlines
will be dropped by Wednesday morning, except in the surf zone where
surf heights and residual swells will continue to support a high rip
current risk at least through Wednesday. Easterly winds will prevail
through the end of the week before returning to southeasterly for
the weekend.

&&

.FIRE WEATHER...

Tropical Storm Gordon will move away from the region tonight with
rain chances returning to near normal levels for the next few days.
With a moist airmass in place, there are no fire weather concerns
through the remainder of the week.

&&

.HYDROLOGY...

Radar estimated storm-total rainfall of 2-3 inches has fallen over
Gulf and western Franklin Counties. An additional 1.5 to 2 inches is
expected across the coastal counties from Franklin westward. These
totals should not result in any significant flooding concerns.
However, rain rates will be high and it is certainly possible that
localize flooding of poor drainage areas could occur near the coast.
The threat appears insufficient for a flood watch at this time.

&&

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @NWSTallahassee.
