area forecast discussion
national weather service tallahassee fl
1028 am edt Wed aug 21 2019

Update
Nudged pops up a bit from the overnight forecast, otherwise the
general forecast remains on track. Southeasterly flow will result
in an active gulf seabreeze and a late day arrival of the atlantic
seabreeze as well.

Prev discussion [611 am edt]
Near term [through today]
Mid level ridge axis will stretch from the central and eastern gulf
of mexico eastward into the western atlantic. Surface flow will be
weak but overall direction will be southeasterly. This will promote
convection developing on the seabreeze late morning and especially
in the afternoon moving north and northwest. Pop chances will be
around average with widespread 40% and the highest chances from
madison and tallahassee northwestward into southeast alabama at
50%. High temperatures today will be in the lower 90s and heat
indices in the lower 100s.

Short term [tonight through Friday]
The diurnal seabreeze circulation will continue to bring scattered
to numerous showers and thunderstorms to the area through the end
of the work week. Low level flow will remain southeasterly on
Thursday, then become more southerly on Friday as the ridge builds
westward. The highest pw values should remain to our west both
days, so we expect the highest coverage of storms to be in our fl
panhandle and southeast al zones both days. Highs will be in the
upper 80s to low 90s and lows will be in the low 70s.

Long term [Friday night through Wednesday]
A pretty typical summertime pattern with seabreeze driven
convection will continue into next week. The area should see the
highest coverage in storms Sunday through Tuesday when rich
moisture returns to the area. Highs will continue to be mostly in
the upper 80s to low 90s and lows mostly in the low 70s.

Aviation
[through 12z Thursday]
fog hasn't developed as earlier thought so have removed from the
tafs. Also, newest guidance shows convection to favor the southern
taf sites of tlh and ecp with more uncertainty of impacting the
other sites. Will metwatch through the day but as of now
confidence is too low to place in tafs with the exception of tlh
and ecp. Winds will be light and mainly from the southeast today
becoming light and variable this evening.

Marine
Light winds and low seas will continue outside of thunderstorms
for the next week. Chances for storms will peak in the late night
and early morning hours.

Fire weather
Aside from low dispersions today, hazardous fire weather conditions
are not expected over the next several days.

Hydrology
A more typical summertime pattern of scattered seabreeze
thunderstorms is expected to continue for the next week, with no
threat for widespread flooding. However, both the econfina and
steinhatchee rivers remain in flood stage from the recent heavy
rainfall- the steinhatchee has crested and the econfina is
currently cresting. Both will see water levels gradually lower
over the next few days.

Spotter information statement
Spotter activation is not requested. However, spotters are always
encouraged to safely report significant weather conditions when they
occur by calling the office or tweeting us @nwstallahassee.

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.
