AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
1045 AM EDT Thu Aug 9 2012

.NEAR TERM [Through Tonight]...
Updated: 1040am

Although things have returned to a more typical summertime pattern
in our local forecast area, it looks like another day with a very
early start to convection. There is a very high coverage of storms
around Bay and Walton Counties. The 4km NCEP WRF runs (ARW and NMM
cores) seem to depict this rather well and therefore our locally-
derived PoP grids from the high-resolution models seem very
reasonable for today. This resulted in PoPs 70-80% west of the
Apalachicola River in FL Panhandle this morning, with likely PoPs
across much of the area this afternoon. Dense cloud cover and
abundant storms will likely limit temperatures around Panama City.
Highs and hourly temperatures were cut back more in line with the
4km NCEP-ARW. However, in the event there is some clearing in the
afternoon, we did not want to reduce highs much lower than 87.

As far as hazards go, the early start to the convection and the
overall abundance of storms may reduce the severe threat a bit
today (like what eventually happened yesterday) despite large
MLCAPE and delta thetae values. We will have to keep an eye on
rain rates and possible flooding again. FFG remains low from
southern Coffee and Geneva Counties into Houston, far S Dale, and
southern Henry Counties in SE Alabama (3-hr FFG generally 3 inches
or less). It is also quite low right in the cities of Dothan and
Tallahassee. These areas would have a greater likelihood to see
some flooding if they receive persistent thunderstorms today.

&&

.SHORT TERM [Friday Through Saturday]...
Current HPC frontal analysis shows a stationary boundary stretching
from west to east from the plains through Ohio River Valley. As
the upper low in Canada dives southeast it will promote
frontogenesis at the surface and strengthen a surface trof. Both
the Euro and GFS show this trof becoming stuck in our area into
Saturday keeping rain chances above normal. This synoptic pattern
will keep more cloud cover around our CWA then is typical of this
time of year and should help keep Highs from the mid to upper 80s
in the more cloud covered areas and into the lower 90s elsewhere.

&&

.LONG TERM [Saturday Night through Wednesday]...
Good agreement overall amongst the extended range guidance this
morning. Sunday begins with a rather familiar pattern with upper
level ridging across the western half of the country, and a
trough/closed low across the eastern half. The southern extension of
the trough will reach our local area and combine with moist low
level southwesterly flow along the western periphery of the
subtropical ridge to provide a good shot for rain area wide on
Sunday. The trough will then flatten and lift north by Monday as the
upper ridge over the western Atlantic merges with the western U.S.
ridge across the southern tier of the country. This will likely
favor below average PoPs within the seabreeze circulation. Another
weaker shortwave rounds the eastern U.S. trough on Tuesday allowing
it to dig back south a bit, nudging the upper ridge south across
southern Florida. This will favor a near climo to below climo N to S
PoP gradient in the form of scattered convection. The east coast
trough slides east for the remainder of the period and ridging
builds in from the west. Will go with slightly below climo seabreeze
PoPs for Wednesday and Thursday. Max temps will remain near average
for the entire extended period.

&&

.AVIATION [Beginning 15Z Thursday]...
The mid-level scattering of clouds held off any widespread dense
fog development this morning, however KDHN did fall to IFR levels
and will remain this way for just a few more hours. It appears
as though with the exception of KDHN, sites will remain VFR this
morning. Showers and isolated thunderstorms will be possible this
morning at KECP, but will likely not make it into KTLH until later
in the afternoon. During the afternoon, expect a greater chance
for rain along and south of a line from KDHN to KCTY. Storms will
likely initiate around 15z to the west, and spread northeast
through the afternoon. As always, expect MVFR to IFR restrictions
in storms, with VFR expected otherwise.

&&

.MARINE...
Winds will be out of the WSW around 10 kts and seas will generally
be 2 to 3 feet. With some possible 4 foot seas in the offshore
waters west of Panama City. Seas will remain 2 to 3 feet through
Saturday, but should remain below cautionary levels.

&&

.FIRE WEATHER...
No concerns.

&&

.TAE WATCHES/WARNINGS/ADVISORIES...
FL...High Risk of Rip Currents through 7pm CDT for coastal parts
     of Bay, Gulf, and Walton Counties.
