Area Forecast Discussion
National Weather Service Tallahassee FL
946 PM EDT Fri Aug 25 2017
.UPDATE...
Showers and storms moving through south-central Georgia this
evening have the potential to produce occasional gusty winds.
These storms will generally move south-southwest along the
instability gradient (a line from about Tifton through
Tallahassee). Expect these storms to persist all the way to the
coast, with convection continuing in the Gulf through the night.
Updated PoPs to reflect this, otherwise no changes were made to
the forecast for tonight.
&&
.PREV DISCUSSION [724 PM EDT]...
.NEAR TERM [Through Tonight]...
Showers and storms will get a late kickoff today but once the east
coast seabreeze and a weak surface trough/frontal boundary interact,
isolated to widely scattered convection should develop this
afternoon and evening. Short term models indicate this convection
developing westward across SW GA and the FL Big Bend and perhaps
reaching the Apalachicola River area by late evening/around midnight
before dissipating. Mostly to partly cloudy skies are expected in
the overnight periods with lows in the mid 70s.
.SHORT TERM [Saturday Through Sunday Night]...
At the start of the period, weak ridging will be in place across
the western half of the forecast area. A tropical disturbance just
inland over the Central Florida Peninsula will be moving NE
across the state and into the Western Atlantic Sat-Sun. This will
result in a fairly tight PoP gradient across the forecast area as
the effects of dry NE flow keep rain chances 10 percent or less
across much of the region, though some areas in the Florida Big
Bend will have a chance of seeing scattered showers and
thunderstorms during the afternoon hours, especially on Saturday
as the tropical disturbance is nearer the area.
By late Sunday, the tropical disturbance is expected to be moving
away from NE Florida and as a result, the area will be left with
fairly light flow and dry conditions to start Monday. Expect
overnight temperatures on Sunday to drop into upper 60s in many
locations.
.LONG TERM [Monday Through Friday]...
At the start of the period, our region is essentially between a
departing tropical disturbance off the US East Coast and a nearly
stationary Harvey across Coastal Texas. This pattern looks to
persist through at least Tuesday and would produce below normal
rain chances in our region. Thereafter, model guidance this cycle
suggests that the trough moving through the Great Lakes on
Tuesday may not induce much northward movement in Harvey by mid
week and as a result, much of the associated tropical moisture
stays more to our west. The net effect of this change from
yesterday results in a forecast for Wednesday through Friday that
features PoPs near climatology for late August (around 40 percent
during the day). High temperatures will be in the upper 80s to
near 90.
.AVIATION [Through 00Z Sunday]...
Scattered showers and storms continue along a line that splits ECP
and TLH as well as ABY and VLD. This trend will likely continue
for the next few hours with the threat of impacted a specific
terminal being low. Near morning, there are indications that an
MVFR cloud deck will impact ABY and VLD, but will likely scatter
before reaching DHN and TLH. Showers and storms will be most
likely late tomorrow afternoon at VLD, TLH, and ECP.
.MARINE...
Swell from Harvey will arrive across the marine area this evening
and persist through the weekend. Even with winds 15 knots or less
through the weekend, seas will reach 4 to 5 feet at times offshore.
With the increase swell, dangerous surf and rip currents are
expected this week along the Florida Panhandle Beaches.
.FIRE WEATHER...
Hazardous fire weather conditions are not expected over the next
several days.
.HYDROLOGY...
The forecast through Tuesday is on the drier side and as a result,
there are no immediate flood concerns. Increasing moisture by
Wednesday could result in some locally heavy rainfall, but given
the dry conditions over the last couple of weeks, any flood risk
is very low.
