AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
645 AM EDT Sat Aug 16 2014

.Near Term [Through Today]...

The 10 pm EDT regional surface analysis showed a weakening,
quasi-stationary front from the GA/SC border to the FL Panhandle.
Vapor imagery and upper air data showed northwest flow aloft over
much of the central and eastern CONUS, with a weak short wave trough
near coastal LA that was essentially cut off from the main
westerlies. Near and on the "cool" side of the aforementioned
frontal system, the air aloft was very dry above 700 mb, and Precip
Water values were 30-40% below climatology. The position of the
front and moisture distribution would suggest minimal rain chances
for most of our forecast area, except a slight chance around Cross
City and Mayo, and the consensus of the latest statistical guidance
and Convection Allowing Models agree. High temperatures will be in
the lower to mid 90s.


.Short Term [Tonight Through Monday]...

With essentially zonal flow aloft, and no appreciable synoptic
forcing, expect the bulk of the shower and thunderstorm activity
to originate offshore. The southwesterly convergent regime will
force showers inland during the morning and afternoon both Sunday
and Monday and will likely disrupt any meaningful seabreeze
circulations. On Monday, our northernmost GA and AL counties may
get clipped by showers and thunderstorms being forced by a
shortwave passing through northern Alabama and Georgia.


.Long Term [Monday Night Through Saturday]...

Nearly zonal flow will gradually be replaced by building upper
level ridging across the SE U.S. through the entire extended
period, while a weak Sfc high pressure system generally remains in
place across the northern Gulf of Mexico. This type of synoptic
pattern with potential stacked ridging should result in a
prolonged period of hot and humid conditions across the entire
CWA, with below normal PoPs forced only by the diurnal sea breeze
circulation. High temps should at least be in the mid 90s away
from the coast, with some upper 90s certainly possible by mid to
late week. Overnight lows will mainly be in the very muggy mid to
upper 70s.

&&

.Aviation...
[Through 06Z Sunday]

Except for a brief period of light fog (MVFR vis) at KTLH & KVLD
this morning, VFR conditions are expected. Winds will be light west
to southwest, picking up a bit out of the southwest this afternoon
to near 10 KT at  KTLH with the onshore sea breeze.

&&

.Marine...

Modest southwesterly flow will prevail for the next few days,
though seas should remain in the 1 to 2 foot range. Expect showers
and thunderstorms each morning.

&&

.Fire Weather...

Red Flag conditions are not expected for the next several days. The
lack of significant, widespread rain the next few days will continue
to allow fuels and soil moisture to dry.

&&

.Hydrology...

Significant rainfall is not expected over the next several days
and all area rivers should remain below action stage.
