Damaging Wind in Florida, July 6, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
225 PM EDT TUE JUL 6 2004

.SHORT TERM...ISOLATED SHOWERS AND THUNDERSTORMS ONGOING EARLY THIS
AFTERNOON...PRIMARILY OVER THE GEORGIA PORTION. RATHER TYPICAL OF A
HIGH INSTABILITY BUT DRY MID LEVEL ENVIRONMENT...STORMS ARE
INITIATING QUICKLY ALONG SURFACE CONVERGENCE BANDS...BUT GROWTH IS
BEING LIMITED BY ENTRAINMENT. EXPECT THIS TREND TO CONTINUE FOR
MOST OF THE FORECAST AREA...BUT A DIFFERENT ENVIRONMENT REMAINS OVER
SOUTHERN PORTIONS. SLIGHTLY MORE MOIST MID LEVELS WILL LEAD TO
SCATTERED COVERAGE THROUGH THIS EVENING. LOOKS AS THOUGH STORMS
WILL HAVE A BETTER CHANCE FOR SUSTAINED DEVELOPMENT...LEADING TO
PERHAPS A PULSE SEVERE STORM WITH WET MICROBURSTS THE LIKELY
CULPRIT.

HIGH HEAT INDICES TO CONTINUE INTO THE EARLY EVENING HOURS WITH
VALUES AS HIGH AS 108 IN AREAS THAT ESCAPE RAIN. WILL CONTINUE TO
HIGHLIGHT IN HWO.

FOR WEDNESDAY...SHORTWAVE TROUGH APPROACHING FROM THE WEST WILL
ALLOW HEIGHTS TO LOWER A BIT...RESULTING IN LESS SUBSIDENCE AND MAX
TEMPS COUPLE OF DEGREES COOLER. WITH DEWPOINTS IN THE 73 TO 76
RANGE...WE WILL STILL BE DEALING WITH HEAT INDICES OF AROUND 103.
WILL PROBABLY BE ABLE TO OMIT MENTION IN ZONES FOR NOW. MODELS BECOME
QUITE DIVERGENT ON POPS BY WEDNESDAY AFTERNOON WITH THE MET GUIDANCE
INDICATING GENERALLY 20 TO 30 POPS AND THE GFS NEARLY 70 PERCENT FOR
THE WESTERN ZONES. WILL FAVOR THE ETA FOR THIS PACKAGE AS IT LOOKS
LIKE THE GFS IS TOO AGGRESSIVE THIS SOON WITH FRONTAL PROGRESSION OUT
OF THE TENNESSEE VALLEY. IN ADDITIONS WEST-NORTHWEST FLOW IS NOT
CLIMATOLOGICALLY FAVORED FOR HIGH POPS...ESPECIALLY ACROSS THE
WESTERN ZONES.

WILL CONTINUE THIS TREND THROUGH THURSDAY AFTERNOON...AS MESOETA
BRINGS CURRENT DRY MID LEVEL AIR OVER THE BAHAMAS AROUND THE
PENINSULA AND INTO APALACHEE BAY. MESO-ETA MAY BE OVERDONE WITH
THIS FEATURE WITH MEAGER POPS DEPICTED FOR THE WEST COAST. WILL
GENERALLY USE A BLEND OF GUIDANCE FOR THESE AREAS.

AS SHORTWAVE EXITS OFF THE EAST COAST...RIDGE ALOFT WILL BE ALLOWED
TO BUILD ONCE AGAIN...TO AROUND 593DM. WILL GENERALLY KEEP LOW END
SCATTERED FOR MOST LOCATIONS...FAVORING INLAND SECTIONS SLIGHTLY.

.LONG TERM...PRETTY MUCH CLIMO CONDITIONS EXPECTED FOR THE LONG TERM
WITH FEW CHANGES TO THE GRIDS. WILL NEED TO MONITOR POSSIBLE WAVE BY
EARLY NEXT WEEK APPROACHING THE NORTHERN CARIBBEAN.
&&

.MARINE...W FLOW MUCH LIGHTER AROUND 5 KT NOW AT 41012 WITH SEAS NEAR
2 FT. SEA BREEZE OCCURRING NOW AT ST AUGUSTINE CMAN. EXPECT FLOW TO
VEER TO S TO SW AROUND 00Z THEN MORE W TOWARD EARLY MORNING DUE TO
RIDGE REMAINING ANCHORED OVER SRN FL. SFC TROUGH MOVING TOWARD THE MID
ATLC COAST ON THU WILL PROBABLY KEEP SFC RIDGE S OF THE AREA UNTIL
FRIDAY WHEN 5H RIDGE BUILDS BACK NWD. SEAS STILL REMAINING MAINLY BELOW
3 FT.
