AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
1021 AM EDT MON JUN 11 2007
...SLIGHT CHANCE OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
AGAIN TUESDAY AFTERNOON...
.PUBLIC...THIS AFTERNOON COULD BE INTERESTING AS MYRIAD INGREDIENTS
ARE EITHER ALREADY IN PLACE OR WILL ESTABLISH DURING THE COURSE OF
THE DAY. MSAS ANALYSIS DEPICTS QUASI-STATIONARY FRONTAL BOUNDARY
STRETCHED ACROSS THE GULF COAST STATES WITH POSSIBLY A SURFACE LOW
NEAR THE APALACHEE BAY. DEWPOINTS REMAIN ELEVATED WITH READING IN THE
LOWER TO MID 70S...WITH HIGHEST READING WHERE FLOW IS ONSHORE. WATER
VAPOR IMAGERY SHOWS EASTERN EXTENSION OF SUBTROPICAL RIDGE IS
ADVANCING SOUTH OVER THE FLORIDA PENINSULA AS SERIES OF DISTURBANCES
ARE CARVING A MEAN-SCALE TROUGH ALONG THE THE EASTERN SEABOARD. THESE
DISTURBANCES WILL PROVIDE A SLIGHT INCREASE OF MID-UPPER LEVEL
MOISTURE AS WELL AS SLIGHTLY LOWER HEIGHTS...WITH AFTERNOON TEMPS
CLIMBING INTO THE LOWER TO MID 90S MOST LOCATIONS...WITH UPPER 90S
POSSIBLE ACROSS THE SUWANNEE VALLEY REGION.
WRT PRECIP COVERAGE...WILL CONTINUE TO INCLUDE SCATTERED POPS FOR
AREAS GENERALLY EAST OF A LINE FROM DOUGLAS TO WAYCROSS TO LAKE CITY
WHERE MOISTURE AVAILABILITY WILL BE SLIGHTLY HIGHER DUE TO ONSHORE
COMPONENT OF LOW-LEVEL WINDS. 12Z KJAX SOUNDING INDICATED CAPE AROUND
4500 J/KG USING AMBIENT TEMPERATURE OF 96 DEGREES AND DEWPOINT OF 73
DEGREES. AFTER MODIFYING THIS SOUNDING USING AMBIENT TEMP OF 92
DEGREES AND DEWPOINT OF 71 DEGREES...A CAPE VALUE OF 3800 J/KG WAS
DERIVED (STILL VERY UNSTABLE). THUS...ANY THUNDERSTORM THAT DEVELOPS
THIS AFTERNOON HAS THE POTENTIAL OF BECOMING SEVERE...WITH CONCERNS
OF DAMAGING WINDS/MICROBURSTS AND MODERATE TO LARGE HAIL (DUE TO
INCREASING SHEAR IN THE MIDDLE-UPPER LEVELS OF THE ATMOSPHERE WHICH
WOULD ENHANCE HAIL GROWTH REGION. MAY BUMP OF POPS 10 PERCENT...
MAINTAINING POPS NO HIGHER THAN CHANCE CATEGORY.
&&
.AVIATION...VFR CONDITIONS TODAY...BUT WILL MAINTAIN TEMPO MVFR IN
VSBYS/CEILINGS IN TSTMS THIS AFTERNOON AT SITE KGNV. WILL MAINTAIN
VCTS WORDING FOR SITES KSSI...KJAX AND KCRG...BUT WILL NEED TO
RE-EVALUTE AS ATMOSPHERE MAY BE SUFFICIENT TO GENERATE GREATER
COVERAGE.
&&
.MARINE...GENERALLY LIGHT ONSHORE FLOW WILL CONTINUE WITH A SLIGHT
INCREASE ON THU. NO HEADLINES EXPECTED.
&&
.FIRE WEATHER...AS ADVERTSIED...DUE TO VERY WARM TEMPS AND DRY AIR
MIXING TO THE SFC THIS AFTN ACROS THE SUWANNEE VALLEY REGION...A RED
FLAG WARNING CONTINUES FOR THIS PORTION.
&&
.JAX WATCHES/WARNINGS/ADVISORIES...
FL...RED FLAG WARNING FROM 1 PM TO 6 PM THIS AFTERNOON FOR BAKER-
COLUMBIA-HAMILTON-SUWANNEE-UNION.
GA...NONE.
AM...NONE.
&&
.PREVIOUS PUBLIC...
OLD FRONTAL SYSTEM WASHING OUT ACROSS THE AREA SHOULD BE THE FOCUSING
MECHANISM FOR SOME CONVECTION THIS AFTERNOON AND AGAIN ON TUESDAY.
SOME OF THOSE THUNDERSTORMS MAY BE SEVERE AS AN UPPER LEVEL TROUGH
ROTATES SOUTHWARD ACROSS THE LOCAL AREA. WILL GO WITH POPS SLIGHTLY
HIGHER THAN GFS MODEL GUIDANCE. OTHERWISE IT WILL REMAIN HOT ACROSS
THE INTERIOR REGIONS WITH PORTIONS OF THE SUWANNEE VALLEY APPROACHING
100 THIS AFTERNOON. GFS IS INDICATING THE JACKSONVILLE METRO AREA MAY
SEE 3.96 INCHES OF RAIN BY WEDNESDAY NIGHT. AS MY LAWN IS SUFFERING
FROM MAJOR CAMEL INFESTATION I WOULD LIKE TO BELIEVE THE MODEL BUT AT
THIS TIME WILL HAVE THE RAINFALL. STILL TWO INCHES WOULD BE NICE IF
WE CAN REALIZE EVEN THAT AMOUNT IF GFS IS TO BE BELIEVED WE MIGHT
SEE SIX TO EIGHT INCHES OF RAIN ACROSS NORTH FLORIDA OVER THE NEXT
TEN DAYS WITHOUT ANY TROPICAL SYSTEM TO TAP GULF MOISTURE. THINK THAT
IS PRETTY GENEROUS FOR A SLIGHT ENHANCEMENT TO NORMAL DIURNAL
CONVECTION. THAT SAID THIS IS ONE TIME WHERE I WOULD REALLY LIKE TO
BE WRONG
