Area Forecast Discussion
National Weather Service Tallahassee FL
326 PM EDT MON SEP 12 2016

.NEAR TERM [Through Tonight]...

Showers and storms will continue into the evening hours then
diminish towards mid to late evening across inland areas. Convection
will increase across the coastal waters tonight and overnight which
will keep a decent flow of cloud cover across much of the area.
Therefore, partly to mostly cloudy skies will be the rule. Low
temperatures will fall into the lower to mid 70s inland and upper
70s at the coast.

.SHORT TERM [Tuesday Through Wednesday Night]...

A tropical wave near the northwestern Bahamas is forecast to
drift northwestward across the Florida Peninsula Tuesday,
approaching our forecast area on Wednesday. This system is weak
and disorganized and the conditions won't be favorable for
development, but it will bring an extremely moist airmass into the
area. Model PW values are above 2 inches, which is well above
normal for mid September. With plenty of moisture in place, even
though forcing will be weak, we expect elevated chances for
showers and thunderstorms Tuesday through Wednesday night.
Southwest Georgia and the Florida Big Bend will see 60-70% chances
during the day Tuesday and Wednesday, still staying to 30-50%
overnight. Further west, chances will be slightly lower, about
40-60% during the day and 20-30% overnight. With increased cloud
cover and rain chances, daytime temperatures will peak in the mid
80s and struggle to reach the upper 80s in a few spots, dipping
into the low 70s in the early morning hours.

.LONG TERM [Thursday Through Monday]...

The tropical wave will dissipate by Thursday, but deep tropical
moisture will remain over the region into early next week. Even
though moisture will be abundant through the period there is
significant discrepancy between the GFS and Euro model
with regards to forcing for widespread precip. The GFS shows a
much wetter pattern with the development of a surface low over the
Florida peninsula on Saturday. The model also moves a weak cold
front through our region Monday evening. On the other hand, the
Euro develops a ridge that lingers over the eastern U.S. seaboard
through the long term period. For this reason, there is
uncertainty with the forecasted pops for Saturday night through
the end of the period. With skies expected to be mostly cloudy
through much of the long term period, expect high temperatures in
the mid to upper 80s and lows ranging in the lower to mid 70s.
Highs will creep back into the lower 90s by the beginning of the
work week.

&&

.AVIATION [Through 18Z Tuesday]...

SHRA/TSRA ongoing west of TLH/AQQ and east of PAM and this entire
area is moving NW at 20 knots. Additional development is expected
from this area west and north through ECP and DHN through the
afternoon. Additionally, east coast seabreeze is moving westward
with convection across southern GA. If it holds together, will
affect VLD around 19Z. It remains to be seen if TLH will be affected
by convection and the possibility is low at ABY.
Convection will wane after sunset with VFR this evening through the
rest of the period.

&&

.MARINE...

As a tropical wave approaches the area, the pressure gradient will
tighten a bit, which will cause a surge in easterly winds and
increase wave heights. By Wednesday night, winds and seas are
expected to lower and remain light through the remainder of the
period.

&&

.FIRE WEATHER...

No concerns.

&&

.HYDROLOGY...

As a disorganized tropical wave approaches the area, showers and
thunderstorms will be likely for the next few days. Widespread 5 day
rainfall totals will be around 1-2.5 inches, but with plenty of
moisture in place, we expect locally higher amounts. Fortunately,
all of our area rivers are back below flood stage, so we don't
currently anticipate any river flooding concerns with rainfall from
this system.
