area forecast discussion
national weather service tallahassee fl
1021 am edt Fri sep 21 2018

Update
While convection is mainly offshore, activity around the panama
city area should increase over the next few hours with a second
area of convection eventually pushing across the suwannee valley
this afternoon as the east coast seabreeze moves into the area.

Main change with the forecast was to increase pops across the
marine area this morning and accounting for some of the east coast
seabreeze storms making it slightly further west. High
temperatures will once again be above normal with highs in the low
to mid 90s.

Prev discussion [635 am edt]
Near term [through today]
Deep layer ridge will be in place today with east to southeast
surface flow and steering flow aloft. Convection chances today will
be the highest across western fl panhandle into SE al where the gulf
coast seabreeze appears to be the strongest. The atlantic seabreeze
will also be active today with east winds, but most of ga will be
underneath strong subsidence aloft so even though that seabreeze may
make it into our eastern zones in the later afternoon, much of this
area will remain dry. I do have 30 pops across the eastern sections
and 40 pops across the western fl panhandle. Otherwise, skies will
be partly cloudy and highs will be in the mid 90s.

Short term [tonight through Sunday]
In the upper levels a ridge will be over the southeast. A weak
trough will be over the northeastern gulf. At the surface a weak
pressure gradient will be over the southeast. A low will be over new
england and a cold stationary boundary will extend through the
tennessee valley and lower mississippi valley. Low level flow will
be easterly or southeasterly. Pops will be 10 to 30 percent on
Saturday afternoon evening with seabreeze showers and thunderstorms
possible. On Sunday afternoon evening pops will be 20 to 45 percent
as deep layer moisture increases. Lows will be in the lower 70s.

Highs will be near 90 or in the lower 90s.

Long term [Sunday night through Friday]
In the upper levels a ridge will be over the southeast. A broad
trough will remain well to the north late in the week. At the
surface high pressure will be over new england and a weak pressure
gradient will be over the southeast. A cold front will approach the
region late next week but will likely stall to the north over the
tennessee valley. The best chance for showers and thunderstorms will
be Monday as deep layer moisture increases, pops 40 to 60 percent.

Otherwise pops will be mainly in the 30 to 50 percent range as the
front nears and stalls to the north. Highs will be near 90 or in the
lower 90s. Lows will be in the lower 70s.

Aviation [through 12z Saturday]
Convection today will favor the western fl panhandle with the gulf
seabreeze convergence area and the eastern fl big bend as the
atlantic seabreeze moves inland later today. Have vcts at ecp this
morning and vld this afternoon. Confidence is too low elsewhere
to mention.VFR otherwise with light east to southeast winds.

Marine
Light to moderate easterly winds are expected through early next
week. Seas will be 2 feet or less.

Fire weather
No red flag conditions are expected over the next several days.

Scattered showers and thunderstorms are expected each afternoon.

Hydrology
Most local rivers are steady or falling. Most local rivers remain
well below action stage. Rainfall totals around 1.5 inches or less
expected over the next week.

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.
