AREA FORECAST DISCUSSION

.Near Term [Through Today]...
The upper low has now moved east of the region leaving cool
advection and deep layer west to northwesterly flow in place
across the region. Aside from a few lingering clouds this morning,
skies are expected to be sunny throughout the day. Temperatures
will likely warm into lower 70s across much of the region. Winds
may be a bit breezy this morning, but these will diminish late in
the afternoon as high pressure builds near the region.
.Prev Discussion [358 AM EDT]...
.Short Term [Tonight Through Friday]...
Dry weather is expected through the short term in the wake of the
departing upper level trough. Surface high pressure will build
over the area by Thursday morning, yielding good radiational
cooling conditions with clear skies and light winds. Below average
temperatures are expected tonight and Thursday night with daytime
highs near average on Thursday and Friday.
.Long Term [Friday Night Through Wednesday]...
By Friday the pattern becomes more zonal. A low amplitude
shortwave trough will slide well north of our area leaving us
under the influence of a ridge, with near normal max and min
temperatures through the extended. Our first real chance or rain
shows up by the end of the period. The GFS and EURO differ on how
they handle the upper-level pattern. The GFS shows the split
stream flow merging over Texas on Monday afternoon which then
develops a potent cut-off low. This solution socks in the entire
SE U.S. with rain, as a Gulf surface low slowly propagates to the
northeast. The Euro does not develop a cut-off low, instead it
moves the trough quickly through the region on Tuesday. The GFS
solution seems more probable given the trend towards Gulf low
development with our recent systems. Either way the beginning of
next week looks to be a wet one.
[Through 06Z Thursday] VFR conditions will prevail for TAF period.
During the day...it will breezy for most sites with offshore winds
averaging around 15 knots with gusts up to 20 knots decreasing to
light after sundown.
Advisory conditions are occurring this morning across the coastal
waters. Expect a gradual decrease in winds and seas through the
day, but seas beyond 20 nm offshore will take some time to
decrease below advisory levels, so the advisory will likely
continue beyond 20 nm offshore for much of the day. Winds and seas
will then decrease through the end of the week as high pressure
builds over the southeastern states.
Much drier will move in with breezy northwest winds resulting in
high mixing heights and dispersions this afternoon...especially
away from the coast. Relative humidities will bottom out in the
low 30s. The airmass will further dry out Thursday with inland
humidities dropping to the mid 20s. However...neither ERC nor 20
foot wind values will reach red flag levels. The airmass will
begin to moisten up on Friday.
Several basins continue to experience flooding or are forecast to
receive flooding at various points, including the Pea River,
Choctawhatchee River, Apalachicola River, Flint River,
Kinchafoonee Creek, and Spring Creek. Other basins such as the
Ochlockonee River, Aucilla River, and Withlacoochee River are in
action stage but are not currently forecast to reach flood stage,
although it may be close at the Withlacoochee River near Valdosta.
