area forecast discussion
national weather service tallahassee fl
1037 am edt Tue aug 22 2017

Update
Low convective temperatures and high pwats will lead to widely
scattered showers and storms today. First along the coast then
this afternoon across the eastern florida panhandle and southwest
georgia. Raised chances and locations to account for latest
trends. Otherwise, forecast appears in good shape.

Prev discussion [634 am edt]
Near term [through today]
Typical summertime pattern has returned to the region, with
moisture at normal levels and convection being driven by the sea-
breeze. Pops will generally range from 40 to 60% today, with the
best chances occurring in the favored seabreeze convergence zone
in the florida panhandle western big bend. Afternoon highs will
reach the lower to mid 90s across the region, with heat indicies
approaching 100f this afternoon.

Short term [tonight through Thursday]
Afternoon convection today is expected to rapidly diminish after
sunset tonight. A typical summer pattern is expected to continue
through Thursday with pops generally in the 30-50% range. As a
weak front moves southward into the northern portions of the area
on Wednesday into Thursday, the highest pops are expected to be
along the front across the northern part of the area. Afternoon
highs are expected to be in the low to mid 90s with overnight lows
in the low to mid 70s.

Long term [Thursday night through Tuesday]
The first half of the long term will likely be near climatology
with scattered afternoon and evening thunderstorms with the
seabreeze and the remnants of a weak frontal boundary in the area.

Late in the weekend into early next week, the forecast will
depend heavily on what happens with a possible tropical system in
the gulf. The 2 am tropical weather outlook from NHC outlooks a
90% chance of development in the next 5 days. All of the global
models show at least some development with differences in track
and timing noted. Most 00z models move the system to somewhere
along the texas coast and then turn it eastward or northeastward
at various speeds while eventually transitioning it into a large
extratropical cyclone as it gets caught up into an upper level
trough. For now, pops will generally be 30-50% through the period
with highs in the upper 80s to low 90s. However, higher pops are
possible next week depending on what happens with the system in
the gulf and if it eventually turns more eastward late in the
period.

Aviation [through 12z Wednesday]
Lifr conditions have developed at dhn and vld within the past few
hours due to low CIGS at vld and low CIGS and vsby at dhn. Expect
improving conditions after sunrise, with restrictions likely
lifting by 14z. Sct tsra is expected across the region today, with
any activity yielding brief vsby and cig restrictions if directly
affecting any terminals. Expect TS to diminish shortly after
sunset Tuesday evening.

Marine
Winds and seas are expected to remain low through the next several
days. Scattered showers and thunderstorms will be possible
throughout the week.

Fire weather
Outside of low dispersions across north florida today, hazardous
fire weather conditions are not expected through the next week.

Hydrology
Scattered showers and thunderstorms are expected over the next few
days. Localized ponding of water is possible in poor drainage areas
with the heaviest rainfall, but widespread flooding is not expected
through the end of the week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
