AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
314 PM EDT MON JUL 9 2012

.SYNOPSIS...
18 UTC surface analysis shows a frontal boundary across Southern
Tennessee and eastward to the Carolina coast. High pressure remains
off the Southeast Atlantic Coast. Showers and thunderstorms are
ongoing across the region with the best enhancement occurring near
Mobile due to an upper level disturbance across Southern Louisiana
and another area of enhanced storms near Tampa due to a mid level
vort moving through the Southeastern Gulf. Temperatures today have
warmed quickly into the mid 90s across the eastern zones and a
little cooler further west where better convective cloud cover is
keeping afternoon temps in the lower 90s.

&&

.NEAR TERM...[Through Tonight].
The near term period will focus largely on diminishing convective
activity across inland areas of Alabama and into Southwestern
Georgia. Convective activity being driven by a combination of the
sea breeze and the upper level disturbance over Southern Louisiana
should die out with the loss of daytime heating. Convection with the
vort over the NE Gulf should be more persistent as the piece of
energy remains over the coastal waters and combines with the land
breeze overnight to enhance convection. Another muggy night is
expected with lows generally in the low to mid 70s.

&&

.SHORT TERM...[Tuesday Through Wednesday Night]
Convective coverage is expected to gradually increase over the next
couple of days as the upper level low over the Lower MS Valley
broadens and a trough near Cuba moves northwest into the central
Gulf of Mexico. On Tuesday, the 1000-700 mb mean vector winds will
back to the southeast (type 6 day). Sea breeze climo favors PoPs
over our western zones, which will also be closer to the upper low.
PoPs will range from 20-40 east to 40-60 west. With the trough
approaching from the south, even more moisture will be drawn
northward into the area and the percentage of the area in the 50-60
PoP range will expand eastward. By Wednesday night, we will begin to
increase PoPs from the south as the surface low approaches. With
this increased convective coverage, temps will not be quite as hot
as recent days. This translates to fewer mid 90s and more lower 90s.

&&

.LONG TERM...[Thursday through Monday]...
The large scale extended forecast remains relatively consistent
during the last few days. The period begins with ridging over west
half of Conus, very broad mid/upper trough from WRN Great Lakes Ewd
into Canadian Maritimes with axis from Ern Great Lakes SWWD across
Wrn Gulf. Looking east, a Bermuda high was noted with axis SWWD
across NE Gulf. The trough continued to become increasingly detached
from the NRN branch of the jet stream. At surface, stalled front
from the Carolinas through Cntrl GA/AL with eroding ridge across NE
Gulf/N FL. All this places local area under deep sly flow regime.

Beginning on Thurs, trough begins to dig SSW with low developing
across Srn OH Valley by late Thurs night into early Fri. Then,
Bermuda High/Wrn Atlc ridge begins to expand WNW across the region
thru Mon allowing low to lift NWD then retrograde into the SRN
Plains. At surface, ridge initially breaks down due to trough
strengthening but then as upper ridge expands WNW, the front begins
to lose its character and surface ridge moves back NWD. Thus local
airmass remains sufficiently moist as deep onshore flow brings a
plume of moisture across local area for much of period leading to
unsettled forecast. Highs PWs combined with slow moving storms and
deep later could lead to locally heavy rainfall especially thru Sat.
Deeper later moisture begins to lift further NWD with the ridge
beginning Sat eve.

Will go with high sct pops Thurs-Sat aftn, otherwise low-mid sct Sun
and Mon aftns and each night. With area in warm sector both min and
max temps will linger at or slightly above climo thru the period.
Avg inland climo is 71/92 degrees.

&&

.AVIATION...
[Through 18Z Tuesday] VFR conditions will prevail through much of
the period with isolated afternoon TSRA expected at ABY/DHN/TLH/ECP
terminals. These storms should end by 01z. Based on persistence and
the latest guidance, opted for MVFR conditions at ABY/VLD around
sunrise. These restrictions will end quickly after sunrise.

&&

.MARINE...
For the next day or so, winds will remain light onshore with some
enhancement in the afternoon sea breeze. A trough of low pressure is
expected to move northwest from the southeastern Gulf of Mexico into
the central Gulf by midweek. As it does so, it is expected to close
off into a weak area of low pressure. The main impact of this low
will be to swing winds around to the southeast. If the low deepens
more than currently expected, then wind speeds will pick up a bit
from Wednesday into Thursday.

&&

.FIRE WEATHER...
Onshore flow keep moisture levels elevated throughout the forecast
period preventing any red flag criteria from being met.

&&
