AREA FORECAST DISCUSSION

.Near Term [Through Tonight]...
The upstream front has pulled up stationary over southern AL just
northwest of our forecast area. It should get moving again once a
short wave over eastern TX approaches overnight. The eastward
progress will definitely be slow, however, as upper level flow is
nearly parallel to the front. Likely PoPs for showers are in the
forecast for our northwestern zones overnight tapering to slight
chance or less over the eastern FL Big Bend. The primary concern
overnight will be how much fog develops. We are fairly confident
that a low stratus deck will overspread the region. It is already
evident in the Big Bend. A lot of the guidance is bullish on dense
fog too. With dew points as high as they are, an advection fog
seems reasonable. An advisory may be issued later tonight. Other
than adding some dense fog wording, the remainder of the forecast
looks on track.
.Prev Discussion [636 PM EST]...
.Short Term [Monday Through Tuesday Night]...
The cold front will move across on Monday with likely Pops for
most of our CWA. We will see lingering PoPs Monday night mainly
east of the river. A drier air mass will filter in on northerly
flow in the low levels. Min and max temps will be noticeably
cooler but not cold as the mid to upper level flow will be nearly
.Long Term [Wednesday Through Sunday]...
The mid to upper level pattern will remain zonal through New
Year`s Day before we see the flow back to the southwest ahead of
the next low pressure system that will translate across the Desert
SW Thursday into the Texas panhandle by Friday night. This system
will then lift rapidly northeastward through the weekend. The
the first opportunity for rain will be Thursday night and Friday as
the warm lifts across the local region. Showers and possibly
thunderstorms will ahead of the cold front will arrive on
Saturday. The GFS shows the front getting hung up with deep
southeast flow remaining in place at least through Sunday. The 12Z
EURO is more progressive with the cold front with it pushing
through on Sunday. Temps will be near to above seasonal levels.
[Through 00Z Monday] There is a high degree of confidence that a
low stratus deck will move in off the Gulf of Mexico overnight.
There will be visibility restrictions as well with VLIFR conditions
possible, especially at VLD. A gradual lift to MVFR ceilings will
occur during the morning daylight hours, but they may not improve to
VFR. A cold front will also move into the area and bring with it
numerous showers. A winds shift behind the front will occur on
Sunday at DHN, ECP and ABY.
Light to moderate winds and low seas are expected to prevail through
the Thursday as weak pressure systems influence the weather
pattern. Winds will be onshore until Monday when a weak cold front
pushes through the waters bringing offshore flow. Offshore flow
will continue until late in the week when they swing around to
become onshore again ahead of the next approaching cold front.
Advisory conditions are possible Friday.
Hazardous fire weather conditions are not expected over the next
The Ochlockonee River above Lake Talquin continues to be in
recession this morning following the crest at Havana on Saturday.
Thomasville has dropped below flood stage this afternoon. However,
Concord will remain at flood stage for the next three days, but will
drop below the critical 38.5 foot level around 2 pm Monday, likely
allowing the reopening of CR-12. The Talquin lake level will
continue to rise throughout the day. Bloxham should stay just
below flood stage.
Over on the Withlacoochee System, the Little River at Havana dropped
below flood stage this morning. Expect areas along the Little River
above the confluence with the Withlacoochee River to see improving
conditions as waters slowly recede from smaller creeks along the
lower portions of the Little River in Lowndes County. The crest wave
within the whole system is just about to the US-84 bridge. This
point is likely to crest around 28.4 feet this evening. Further
downstream to Pinetta, rises will continue with the potential for
minor flood stage being met after the first of the year.
Releases from Woodruff on the Apalachicola River have stabilized at
32000 cfs, and are now at a level that Blountstown should stay below
flood stage absent any additional adjustments to the release
In the Choctawhatchee River, Caryville crested yesterday and is now
below flood stage. Further down river, Bruce will continue to rise
and go above flood stage later this evening. A crest around 13.5
feet should occur Monday evening.
Future rainfall through the next 48 hours is anticipated to be in
the 0.75 to 1.25 inch range with heaviest values across the
northwestern portions of the region. This storm system Sunday night
and into Monday should have only a limited impact on area river
levels only briefly slowing the rate of decrease at the forecast
points. A short period of quiet weather is expected throughout the
remainder of the week before a stronger storm system approaches the
area next Saturday. With little opportunity to dry out from the
recent heavy rains, the flood potential will remain elevated across
the region with river flows now well above normal.
