.Near Term [Through Tonight]...
Strong shortave rounding the base of the persistent central U.S.
trough is helping to induce sfc cyclogenesis over the Florida
Peninsula this evening. This feature is also providing the lift
for one more round of light to moderate rain across the forecast
area. As this shortwave exits the area late tonight, expect to see
the rain come to an end, followed shortly by clearing skies. Back
edge of clouds is currently moving into eastern Mississippi. Made
a few adjustments to the PoPs this evening based on radar trends,
but no other significant changes were needed.
[Through 00Z Thursday] Remaining low cigs at KTLH and KVLD will
slowly lift with VFR conditions expected at all terminals by
around 10-12UTC. Remaining light rain will also come to an end
overnight, with dry conditions on Wednesday.
.Prev Discussion [240 PM EST]...
.Short Term [Wednesday Through Thursday Night]...
There is a 20-30% chance of rain for our eastern zones Wednesday
morning from the wrap around moisture associated with the cold
front, but once the system lifts off to the northeast in the
afternoon, we will start to notice the colder, drier air moving in
as surface high pressure starts to build eastward. This airmass
won`t be as cold as last week`s cold front, but highs will struggle
to reach 60 both Wednesday and on Thanksgiving despite clearing
skies. Lows will return to the mid to upper 30s, with a light
freeze (brushing around 32F for an hour or so) even possible in
our northwestern zones Thursday night.
.Long Term [Friday Through Tuesday]...
High pressure will continue to push eastward over the southeastern
states through the long term period. There are no significant
chances of rain through the period, although cloud cover and
moisture will begin to increase again early next week. The airmass
will be cool and dry through Friday night, with highs in the upper
50s to around 60 and lows in the mid to upper 30s. Over the
weekend however, the airmass will begin to modify and we will
warm up a bit to highs in the mid 60s to low 70s and lows in the
40s to around 50.
Winds and waves will continue to ramp up overnight, with seas
peaking at 7 to 9 feet occasionally as high as 11 feet and gusts to
gale force possible over the offshore waters. Winds will begin to
decrease Wednesday morning and by Wednesday afternoon, winds and
waves will fall below headline criteria and remain so for the
remainder of the period.
Much drier air will move into the region over the next few days,
with minimum humidity values in the 30s and 40s. However, with very
wet fuel conditions, there are no fire weather concerns.
For the last few days, ending at 18z today, between 2 and 4 inches
of rain had fallen across the region, with isolated maximum totals
in of 5 inches across Southwestern Georgia and into the Florida
Panhandle. Over the next 18 to 24 hours, an additional 1 to 2 inches
is possible, primarily focused across the Florida Panhandle and into
Southwestern Georgia. The areal flood potential through the
remainder of this event is low. However, steady rises will continue
through much of this week on area rivers. Given the bulk of the
rainfall occurring in the Flint/Ochlockonee River basins, expect
the most notable rises in these basins, particularly below Newton
and Thomasville, respectively. Thomasville and Concord may reach
action stage in the days ahead. However, these and all river points
are expected to remain below flood stage.
