1020 AM EDT WED AUG 2 2006

...DANGEROUS HEAT AND HUMIDITY TO CONTINUE ACROSS THE AREA TODAY...

.SHORT TERM /TODAY/...SPRAWLING UPR LVL RIDGE ALONG WITH SFC HIGH
PRES WILL MAINTAIN EXCESSIVELY HOT CONDS OVER THE AREA TDA. VIS SAT
PIX SHOWS NO CLOUD COVER ACRS CHS CWFA...ALTHOUGH SOME MIDLVL CU
DEVELOPMENT IS XPCTD LATER ON. MODEL 1000-850 THICKNESSES STILL
DEPICT HIGHS OF AT LEAST 100 OVER ALMOST THE ENTIRE CWFA WHILE MOS
GUIDANCES RANGE FROM 97-102 AT VARIOUS SITES. NATURALLY...THE
SEABREEZE WILL BRING SLIGHTLY LOWER TEMPERATURES TO COASTAL LOCALES
BUT THE THE DEWPOINT WILL TAKE OVER TO BRING THE HIGH HEAT INDICES
TO THOSE LOCATIONS. SPEAKING OF DEWPOINTS...AM CONCERNED WITH THE
FACT THAT DEWPOINTS ARE STILL IN THE MID 70S AS OF 14Z AND WITH
NOTHING TO ALLOW THE DEWPOINTS TO SUBSIDE...HAVE TWEAKED UP
DEWPOINTS A DEGREE OR TWO IN THE GRIDS WHICH EXPANDS THE AREA THAT
HEAT INDICES OF ARND 115 DEGREES MAY BE SEEN. THEREFORE...HAVE OPTED
TO INCLUDE A FEW MORE COUNTIES IN THE EXCESSIVE HEAT WARNING ACROSS
INTERIOR SC AND EFFINGHAM COUNTY IN SE GA...THEREBY CAPTURING ALL OF
THE I-95 CORRIDOR IN SC AND SLIGHTLY IN SE GA. FOR THE REST OF SE GA
AND ALLENDALE COUNTY SC...HEAT INDEX VALUES SHOULD FALL SHORT OF
WARNING CRITERIA BUT WILL CERTAINLY MAINTAIN THE HEAT ADVY THERE
WHERE HEAT INDEX VALUES WILL REACH AT LEAST 105.

WILL ALSO MAINTAIN /SILENT/ 10 POPS ACRS THE AREA AS WV IMAGERY
DEPICTS THE DRY MID AND UPR LVLS QUITE WELL WITHIN THE WIDESPREAD
SUBSIDENCE OF THE LARGE UPR LVL RIDGE. THERE MAY BE AN ISOLD POP-UP
SHWR OR TSTM HERE OR THERE ACRS THE CWFA...BUT NOT ENOUGH COVERAGE
TO WARRANT MENTION.

WILL ISSUE UPDATE FOR THE REARRANGEMENT OF THE HEAT WRNG AND HEAT
ADVY...BUT THE ELEMENTS OF THE FCST WILL REMAIN PRETTY MUCH THE SAME.
&&

.AVIATION...MAINTAINED VFR CONDS AT BOTH TERMS WITH LARGE HEAT DOME
OF HIGH PRES REMAINING OVR THE AREA. ONLY CONCERN WILL BE VSBY
RESTRICTIONS TO THE MVFR CATEGORY DUE TO HAZE LATER TDA. WILL
MONITOR 5-MIN ASOS OBS AT BOTH SITES BUT WILL ONLY GO SO FAR AS 6SM
HZ ATTM. PRECIP CONCERNS ARE MINIMAL WITH POPS OF 10 PERCENT...AND
WINDS WILL SHIFT FROM WSW TO SSW THIS AFTN WITH THE SEABREEZE.
&&

.MARINE...BUOYS ARE RIGHT ON TRACK WITH ONGOING FCST...OF SW WINDS
10-15 KT AND SEAS AOB 4 FT. WILL MAKE MINOR TWEAKS FOR THE AFTN
WORDING...BUT ONGOING FCST HAS EVERYTHING IN CHECK WITH HIGH PRES AT
THE SFC AND ALOFT DOMINATING THINGS TDA.
&&

.CHS WATCHES/WARNINGS/ADVISORIES...
