...DANGEROUS HEAT TO CONTINUE ACROSS THE AREA THROUGH FRIDAY...

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...SLIGHTLY WEAKENING HIGH
PRES RIDGE ALONG WITH NEARBY SFC TROF MAKING FOR ANTICIPATED BETTER
COVERAGE OF SHWRS/TSTMS THIS AFTN. NEVERTHELESS...TEMPS HAVE STILL
SOARED INTO THE MID AND UPR 90S AND DEWPTS IN THE MID AND UPR 70S...
MAKING FOR ANOTHER DAY OF OPPRESSIVE HEAT. WILL MAINTAIN EXCESSIVE
HEAT WRNG AND HEAT ADVISORIES AS THEY ARE THRU THE REST OF THIS

RAPID REDUCTION IN TEMP. EVEN SO...HEAT INDICES OF 105-115 HAVE BEEN
SEEN ACRS THE CHS CWFA TDA.

STAGNANT HUMID CONDS WILL REMAIN OVR THE AREA TNGT...KEEPING LOWS IN
THE UPR 70S AND LWR 80S. SHWRS/TSTMS MAINLY A FUNCTION OF SFC
HEATING FOLLOWED BY BOUNDARY INTERACTIONS WITH EACH OTHER AND THE
SEABREEZE. THE POTENTIAL IS STILL THERE FOR A FEW STRONG TSTMS VIA
WET MICROBURST. THE SETTING SUN SHOULD DISSIPATE ANY AND ALL
SHWR/TSTM ACTIVITY SO WILL ONLY KEEP POPS DURG THE EVE HRS.

THE HEAT WILL AGAIN BE A PROBLEM TMRW...BUT NOT QUITE TO THE DEGREE
SEEN TDA AND YDA. AN INCRS IN MIDLVL MOISTURE ALONG WITH A MORE
DEFINITIVE SFC LOW PRES WAVE APCHG FM THE WEST WILL KEEP MORE CLOUDS
OVR THE AREA...LEADING TO MAX TEMPS MAINLY IN THE LOW AND MID 90S.
DEWPT VALUES SHOULD BE ABOUT THE SAME...IN THE MID TO POSSIBLY UPR
70S...THUS LEADING TO HEAT INDICES ARND 105 AND TOPPING OUT AT 110.
HAVE OPTED TO ISSUE A HEAT ADVY FOR THE ENTIRE CWFA TMRW. AS FOR
PRECIP...THE AFOREMENTIONED SFC WAVE ALONG WITH A DEEPER MOISTURE
COLUMN LOOK TO BE ENOUGH TO HAVE GREATER COVERAGE THAN TDA. IN
ADDITION...THE UPR LVL RIDGE CONTINUES TO WEAKEN FURTHER FRI SO HAVE
INCRD POPS INTO THE CHC CATEGORY FOR ALL AREAS...DROPPING TO SLGT
CHC TMRW NIGHT.

SOME MINOR DIFFERENCES CREEPING INTO THE PICTURE BY THE MIDDLE OF
THE UPCOMING WORK WEEK. ZONAL UPPER FLOW SAT WILL GIVE WAY TO
RIDGING SUN THROUGH TUE AS H5 HEIGHTS BUILD ACROSS THE SE CONUS.
UPPER RIDGE WILL RETROGRADE WESTWARD INTO THE LOWER MS VALLEY WED
AND THU...ALLOWING H5 HEIGHTS TO LOWER AND WEAK UPPER TROUGHING TO
GET ESTABLISHED ACROSS THE REGION.

AT THE SFC...WEAK FRONTAL BOUNDARY WILL PUSH TOWARD THE REGION SAT
THEN DISSIPATE OVER THE REGION ON SUN. WILL CONTINUE TO MENTION LOW
CHC POPS FOR MAINLY AFTERNOON EVENING SEA BREEZE AIDED CONVECTION.
HIGH PRESSURE WILL GET RE-ESTABLISHED MON AND MON NIGHT...BEFORE
NEXT FRONTAL BOUNDARY BEGINS TO APPROACH THE AREA TUE. WILL RUN WITH
SLGT CHC POPS MON...WITH LOW CHC POPS TUE AS FRONTAL BOUNDARY BEGINS
TO PUSH INTO THE REGION. MODELS DIFFER ON HANDLING OF BOUNDARY WED
AND THU...WITH THE 12Z GFS NOW INDICATING FRONT WASHING OUT NORTH OF
THE FORECAST AREA. 00Z ECMWF/00Z UKMET/00Z GFS/12Z CANADIAN...ALL
INDICATE THAT FRONTAL BOUNDARY WILL SAG SOUTHWARD INTO THE FORECAST
AREA WED AND STALL OUT OVER THE REGION ON THU. WILL FOLLOW MODEL
CONSENSUS HERE AND CONTINUE WITH MID RANGE CHC POPS ACROSS THE AREA.
TEMPERATURES ARE EXPECTED TO RUN NEAR TO SLIGHTLY ABOVE NORMAL
THROUGH THE EXTENDED PERIOD.
&&

.MARINE...LARGE AREA OF SFC HIGH PRES WILL REMAIN OVR THE COASTAL
WATERS THRU THE START OF THE WEEKEND. ALTHOUGH A WEAK SFC TROF WILL
APPROACH THE WATERS AND POSSIBLY CREATE NOCTURNAL SURGES TNGT AND
TMRW NGT...PRES GRAD WILL NOT BE IMPRESSIVE SO WILL KEEP SPEEDS AOB
15 KT AND SEAS AOB 4 FT.

TRANQUIL WEATHER TO CONTINUE THROUGH THE EXTENDED PORTION OF THE
MARINE FORECAST SAT THROUGH TUE. A WEAK FRONTAL BOUNDARY WILL PUSH
SOUTHWARD TOWARD THE AREA SAT...THEN DISSIPATE WELL NORTH OF THE
WATERS SUN. HIGH PRES WILL THEN GET RE-ESTABLISHED ACROSS THE AREA
FOR MON AND TUE. WINDS ARE EXPECTED TO REMAIN AOB 15 KT...WITH SEAS
AOB 3 FT COASTAL WATERS AND AOB 4 FT OUTER GA WATERS.

.AVIATION...VFR CONDS WILL CONTINUE TO BE THE RULE AT BOTH TAF SITES
BUT AM STILL CONCERNED ABOUT VSBY RESTRICTION DUE TO HAZE. SEVERAL
LOCATIONS ARND THE AREA HAVE DROPPED TO 6SM SO HAVE INCLUDED SAME AT
BOTH KSAV AND KCHS THRU THE REST OF THE DAYLIGHT HRS TDA. SCT MIDLVL
CLOUDS WILL THIN OUT AND DISSIPATE THIS EVE AND TNGT...THEN POP UP
AGAIN TMRW AFTN. AS FOR PRECIP...KCLX RADAR IS SHOWING SOME ECHOES
DEVELOP BUT SHORT-LIVED NATURE AND ISOLD TO SCATTERED COVERAGE MAKE
IT DIFFICULT TO INCLUDE ANYTHING OTHER THAN CB/S ATTM. WILL CONTINUE
