AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
645 AM EDT Fri Apr 18 2014

.Near Term [Through Today]...

The 03 UTC regional surface analysis showed a rather wavy, east-west
oriented frontal boundary from central FL through the Gulf of
Mexico. There was no closed surface low yet, but all of the global
models insist that one will form in the northern Gulf by around
dawn. Vapor imagery and upper air data showed an approaching potent
trough over TX, though a preceding short wave trough appeared to be
translating northeastward over the FL Panhandle. It's this initial
short wave trough that is associated with the massive blowup of deep
moist convection over the eastern Gulf of Mexico early this morning.
Widespread rain from these MCSs has spread over most of our forecast
area, and we expect this will continue throughout the day. With
precip water values 50 to 100% above climo, rain rates will
occasionally be very high, so we will leave our Flood Watch up and
unchanged for our entire forecast area. The global model consensus
brings the surface low near Apalachicola by late afternoon.

Although there will be a lot of rain and clouds today, the mean of
the Convection Allowing Model (CAM) forecast SBCAPE is in the 500-
1000 J/kg range this afternoon around Cross City and Perry. Given
the expected 0-1 km bulk shear magnitude will be around 30 KT in
that area, it's reasonable to be concerned about isolated,
low-topped supercells- with damaging wind gusts or perhaps even a
brief tornado. Elsewhere we think that thunderstorms will be
elevated enough to limit vertical mixing, though the low level winds
are strong enough that wind gusts up to 40 MPH are possible.

.Short Term [Tonight Through Sunday]...

The surface low pressure system will be departing to our east
tonight but rain chances will continue through Saturday as wrap
around moisture associated with the upper low swings through the
Tri-state region. Most of this rain should be light. Deep layer
ridging will begin to build in on Sunday with warming temperatures
and dry conditions.

.Long Term [Sunday Night Through Friday]...

By early next week the next weak trough and shortwave moves into
Gulf region with weak zonal flow across local area. A surface low
well to our NW brings a weak front to the Nrn Gulf before retreating
back Nwd on Wed. This will bring a slight chance of rain and isold
thunderstorms to the NRN counties Tues and Tues night followed by
drying trend.  Throughout the entire period, both high and low temps
will shows a gradual warming trend. Inland highs Monday in the upper
70s to around 80 will rise to the mid 80s Wed and Thurs. Inland Lows
Sun night in the low to mid 50s will rise by Thurs night to the low
60s.

&&

.Aviation...

[Through 12z Saturday] Rain, occasional thunderstorms, and low
cigs (lower MVFR to IFR) are expected at all terminals today. The
heaviest rain will end from south to north this evening, followed
by IFR cigs and occasional DZ.

&&

.Marine...

Winds and seas will continue to increase today with gale
conditions developing over the western and offshore legs. For the
nearshore waters of the Big Bend...advisory conditions will
prevail at least through the passage of the low pressure system
tonight. The gale conditions for the remainder of the coastal
waters will also subside tonight with advisory conditions
diminishing by Saturday evening. The strong onshore flow will
result in heavy surf and high risk of rip currents along area
beaches from Franklin County westward. A coastal flood watch is
also in effect along Wakulla County eastward to the mouth of the
Suwannee River.

&&

.Fire Weather...

With such wet conditions today, there will be no fire weather issues
(i.e. Red flag conditions) through at least this weekend.

&&

.Hydrology...

We continue to be on track for a moderate to heavy rainfall event
across much of the forecast area Friday and into Friday Night.
Rainfall totals of 2 to 3 inches are expected to be fairly common,
with higher amounts perhaps up to 5 to 6 inches will be possible.
In general, the rivers most likely to flood and have higher
impacts will be in the Florida Panhandle and Big Bend where flows
are already somewhat elevated. Where the heaviest rain falls,
there should also be other flooding on smaller streams and creeks,
as well as areas of high water in low-lying areas and fields.
