area forecast discussion
national weather service tallahassee fl
909 am edt Mon aug 20 2018

Update
Low clouds across portions of the area are beginning to mix out as
the daytime boundary layer gets underway. The 12z tae sounding
indicated precipitable water (pw) values around 1.65 inches, much
lower compared to yesterday. Meanwhile, pw values remain around
2.0 inches to the northwest. This will result in a pop gradient
across the area today as mentioned previously. With mixing up to
around 5k ft, the 12z tae sounding supports high temperatures near
90 degrees away from the gulf coast, except mid-upper 80s from
the western fl panhandle to northwest of the snake river, due to
cloud cover. No major changes were made to the forecast.

Prev discussion [645 am edt]
Near term [through today]
While the local area will reside under a low wavelength ridge
through the day, the persistent tongue of tropical moisture will
remain along and northwest of a line from panama city through
tifton. The southwesterly mean flow regime will favor an early start
to convection initiated along the landbreeze seabreeze transition
zone. While the southwesterly regime tends to be one of our wetter
regimes, dry air aloft will limit coverage to below climo to the
east of the aforementioned delineation. Along and west of this line,
the plume of tropical moisture will result in above normal pops for
this regime. High temperatures will once again be held in the 80s
where rain is more widespread, and in the lower 90s elsewhere.

Short term [tonight through Wednesday]
An upper low over the midwest tonight will open up as it
translates eastward across the great lakes Tuesday Tuesday night.

The associated surface cold front will approach our northwest
zones by late Tuesday. The axis of the upper trough and cold front
is forecast to continue to move east and pass through our area on
Wednesday. The deepest moisture and best forcing will be over the
western half of our CWA Tuesday ahead of the upper trough and
cold front. Pops will be tapered good chance likely northwest to
slight lower end chance southeast. By daybreak Wednesday, the
front is forecast to extend roughly from valdosta southwest to
near panama city. Pops will generally be along and south of the
boundary as a drier airmass will be filtering in across the
remainder of the fa. While the airmass will be drier, there won't
be any noticeable change in temperatures in the wake of the front.

Long term [Wednesday night through Monday]
Forecast soundings and time-height cross sections show a much
drier airmass over the area Thursday. However, this will be
short lived as moisture quickly returns on easterly flow Friday as
surface high pressure centered north of our area moves eastward.

Scattered mainly afternoon showers and thunderstorms will return
Friday and this pattern should continue through the remainder of
the weekend into early next week.

Aviation [through 12z Tuesday]
Lifr restrictions have impacted aby this morning, but should clear
shortly after sunrise. Restrictions never materialized at dhn.VFR
will likely prevail at all terminals through the TAF (outside of
thunderstorms).

Marine
Generally light winds and low seas are expected through the week.

Winds and seas will increase slightly as a cold front approaches
and passes through the waters Tuesday through Wednesday.

Fire weather
Hazardous fire weather conditions are not expected over the next
several days.

Hydrology
Total forecast rain amounts will average around 1.5" along and
west of the apalachicola and chattahoochee rivers over the next 7
days. Elsewhere, amounts around 1 inch are forecast. Therefore,
latest river guidance keeps all rivers just below action stage.

Locally higher amounts are possible and will likely occur so
flashier rivers and streams may still rise as well as low lying
and flood prone areas.

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.
