Area forecast discussion, Aug 14, 1:48 PM CDT, 2 hours 55 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
248 PM EDT Tue Aug 14 2012

.NEAR TERM [Through Tonight]...
Passing shortwave trough will continue to trigger scattered to
numerous showers and thunderstorms through the early evening
hours. Continue to see a few strong wind gusts with the
thunderstorms along with vivid lightning. However, significant
severe weather does not appear likely since much of the area has
been stabilized by rain- cooled air. The activity will taper off
this evening with the best rain chances overnight over the Gulf
waters and immediate coast.

&&

.SHORT TERM [Wednesday Through Thursday Night]...
Broad trough will remain in place over the region through
Wednesday before the flow becomes more zonal on Thursday.
Shortwave wave energy forecast to cross the region on Tuesday does
not appear as strong as today's feature. Guidance also indicates
some drier mid-level air working into the region. Therefore, not
expecteing as much precip coverage for Tuesday afternoon and have
drawn only isolated to scattered PoPs for the afternoon hours.

While deep moisture is forecast to increase slightly on Thursday,
the increasingly weak zonal flow will not provide a lot of large
scale forcing for convection, so will mainly rely on seabreeze to
get things going. For now, have kept PoPs in the low- end chance
category.

Lower rain coverage should lead to higher afternoon temperatures
for Wednesday and Thursday with highs reaching the lower to mid
90s.

&&

.LONG TERM [Friday through Tuesday]...
The large scale longwave pattern commences with ridging over Wrn
states, broad trough over Cntrl states Ewd to Appalachians, weak
shortwave ridge Ewd to ERN seaboard and trough from low Canadian
Maritimes SWD down WRN Atlc. At the surface, main features surface
ridge axis extending from the WRN Atlc to across the Cntrl Gulf and
a cold front from Ontario S then SW thru vcnty Memphis then across
TX Panhandle. This places local region in semi-zonal flow aloft and
wsw flow at surface.

During the rest of the period, ECMWF/GEFS/UKMET in good agreement
with both upper and lower features. Aloft, aided by passing short-
waves, upstream trough amplifies and digs SEWD with anchoring closed
low over Hudson Bay and axis SWD into ERN Gulf on Fri. Amplified
troughiness will exist over local region thru weekend. Trough then
lifts NEWD on Mon and especially on Tues with drier NW flow and
subsidence overspreading NE Gulf from NW-SE. At surface, as the
upper trough digs, GFS lifts ridge axis NWD and Canadian low moves
progressively ESE with impulses helping to drag cold front SEWD into
N/Cntrl AL/GA by FRI eve and to SRN AL/GA on Sat with PWs,
increasing to over 2 inches, before becoming stationary thru early
Mon. This places local area in favorable zone for deep tropical
moisture, ample locally heavy rain and possible strong to severe
storms especially if shortwaves pass during times of max diurnal
heating. Front begins to lift NWD on Mon and progressively weakens
under influence of lifting upper trough.

Will go with daytime POPs of high sct Fri thru Sun then mid sct Mon
and low sct on Tues. Generally wdly sct-low sct pops at night. With
local area in the warm cloudy sector, min temps will persist at 2 to
4 degrees above climo and max temps around climo thru the period.
(Avg inland Min/Max is 70/91 degrees).

&&

.AVIATION [Beginning 18Z Tuesday]...
Ongoing convection is expected to continue through at least 22z
in vicinity of TLH/VLD with much less coverage at the remaining
terminals. Debris cloudiness should clear quickly overnight
resulting in a good chance of MVFR/IFR conditions at the TAF sites
around sunrise. Convective coverage is expected to be much less
tomorrow and start later in the day, thus left mention out of
storms tomorrow of the 18z TAF package.

&&

.MARINE...
The subtropical ridge is forecast to remain south of the waters
through much of the week. This will keep light west to southwest
flow and minimal seas in place over the coastal waters outside of
convection.

&&

.FIRE WEATHER...Low levels will remain very moist through the end
of the week, with no fire wx concerns expected.

&&

.TAE WATCHES/WARNINGS/ADVISORIES...
FL...None.
GA...None.
AL...None.
