area forecast discussion
national weather service tallahassee fl
1010 pm edt Sun sep 24 2017

Near term [through tonight]
00 utc surface analysis shows an area of high pressure across
pennsylvania and hurricane maria well off the coast of the
southeast. Our region remains in northeasterly flow. Upper level
data this evening and vapor imagery showed the presence of a weak
disturbance across southern mississippi. Earlier today a large
area of convection was over the offshore waters of the florida
panhandle. Radar data did show a weak mid level MCV moving toward
the florida panhandle coast and that seems to have since
weakened. It would not at all be surprising with the upper trough
remaining in place across the central gulf coast states to see
some redevelopment of showers and thunderstorms over the waters
tonight. As a result, will keep 40-60 percent rain chances across
the panhandle waters tonight.

Prev discussion [747 pm edt]
Short term [Monday through Tuesday night]
An upper level low situated near the central gulf coast tomorrow
morning will slide eastward and over florida on Tuesday. This
feature, combined with enough moisture (pw values of 1.7-1.9) will
allow for the chance of showers and thunderstorms across the western
half of the CWA on Monday. With the upper low shifting eastward on
Tuesday and winds becoming northerly, drier air will filter in with
pw values dropping to 1.3-1.6. This will help to limit convection
and thus pops are limited to 10% or less on Tuesday. Highs will
remain around 90 with lows in the upper 60s to lower 70s.

Long term [Wednesday through Sunday]
The upper low will meander in the eastern gulf off the west coast
of florida with drier air (pw around 1.2) in place for the
beginning of the long term. This will allow for a dry forecast and
do not have mentionable pops in the grids for Wednesday and
Thursday. A weak front late in the week into the weekend will
allow for the return of 20-30% pops, but overall rain chances are
still on the lower side with the front. While temperatures for
the beginning of the long term will climb into the low 90s, highs
for the weekend are expected to drop into the low to mid 80s. Lows
in the lower 70s will drop into the 60s for Sunday and Monday
morning.

Aviation
[through 00z Tuesday] convection near ecp will continue to weaken
this evening. Otherwise,VFR conditions are expected to prevail
through the period.

Marine
East winds around 10 knots tonight will decrease to 5 to 10 knots
by Monday afternoon with winds 10 knots or less through mid week.

By the weekend, winds and seas will increase. While scattered
showers and thunderstorms are expected across the western waters
again Monday, chances will decrease for mid week.

Fire weather
Red flag conditions are not expected for the next several days.

Hydrology
Overall rainfall amounts through Monday will be limited to around
0.25 inches or less and these low amounts will not cause any
flooding issues. Much of the rest of the week will remain dry.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they

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.
