Area forecast discussion, Jan 25, 3:10 AM EST, 1 hour 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
310 AM EST MON JAN 25 2010

...GUSTY WINDS WITH PRE-FRONTAL CONVECTION TODAY...
...LAKE WIND ADVISORY TODAY...

.SYNOPSIS...PRE-FRONTAL CONVECTION WAS TRACKING EAST ACROSS THE JAX
CWA. THE STRONGEST LINE EXTENDED FROM SSI SW TOWARD GNV. ISOLATED TS
FORMED IN THE LINE ACROSS SE GA EARLIER TONIGHT WHERE UPPER LEVEL
DYNAMICS WERE STRONGEST BUT NOW THAT THE SFC LOW HAS LIFTED
NORTHWARD ACROSS THE WESTERN CAROLINAS TS ACTIVITY HAS DECREASED
OVER OUR GA ZONES. FARTHER SOUTH ACROSS N FL SCATTERED TS CONTINUED
TO FLARE-UP WHERE SFC BASED INSTABILITY REMAINED IN PLACE (AROUND 2
AM OCALA WAS 73/70).

STRONG LOW LEVEL WINDS BETWEEN 3-4 KFT AROUND 55-65 KTS WERE OVER THE
AREA PER THE JAX VAD. LAKE WIND ADVISORY CONDITIONS CONTINUED ACROSS
OUR FL ZONES WITH A STRONG PRESSURE GRADIENT IN PLACE PRECEDING THE
SFC COLD FRONT...AND PRESSURE RISES TRAILING THE CONVECTION ON THE
ORDER OF 2 TO 3 MB/3-HR. THE STRONGEST RECENT GUST OF 43 MPH WAS
ASSOCIATED WITH CONVECTION AS IT PASSED THROUGH PERRY FL. WITH
SEVERAL GRADIENT AND DYNAMICAL MECHANISMS IN PLACE...EXPECT WIND
GUSTS BETWEEN 35-40 MPH WILL BE COMMON IN CONVECTION TONIGHT...AND
GIVEN WET GROUNDS IN MANY LOCATIONS...THESE CONDITIONS COULD CAUSE
SOME DAMAGE TO TREES.

.SHORT TERM...TODAY THROUGH THU...
THE BULK OF PRECIP WILL BE OFFSHORE OF THE COAST BY 12Z...BUT PVA
ALOFT AND LINGERING SFC INSTABILITY WILL CONTINUE TO SUPPORT A
CHANCE OF EARLY MORNING SHRA AND ISOLD TS FROM SSI TO GNV EASTWARD.
TRAILING THE HEAVIER PRECIP LIGHT LIGHT SHRA ACTIVITY NOW ACROSS SW
GA AND THE FL PANHANDLE WILL BE POSSIBLE WESTWARD TOWARD WAYCROSS
AND LIVE OAK THROUGH MID-MORNING. BY EARLY AFTN CONVECTION WILL BE
CLEAR OF THE CWA. MAX TEMPS WILL WARM INTO THE MID/UPPER 60S UNDER
WINDY WESTERLY FLOW AND CLEARING SKIES. WILL CONTINUE THE LAKE WIND
ADVISORY FOR ALL ZONES THROUGH THIS EVENING WITH SUSTAINED SPEEDS
AROUND 20 MPH AND GUSTS FROM 30-35 MPH.

TONIGHT & TUE...UPPER LEVEL FLOW WILL CONTINUE FROM THE SW WITH DEEP
TROUGHING STILL UPSTREAM OF THE AREA AS SFC HIGH PRESSURE BUILDS
SOUTH AND EAST FROM THE CENTRAL CONUS TO THE GULF COAST REGION. WEST
WINDS WILL DECREASE TONIGHT BUT WILL NOT GO CALM...SO HAVE TRENDED
ON THE WARM SIDE OF MOS. TUE LAKE WIND ADVISORY CONDITIONS ARE
LIKELY AGAIN AS WELL AS SOME PASSING HIGH CLOUDS AS THE UPPER TROUGH
FINALLY PUSHES DOWNSTREAM OF THE EASTERN CONUS.

TUE NIGHT THROUGH THROUGH WED NIGHT...UPPER LEVEL FLOW WILL BECOME
ZONAL AS THE SFC RIDGE SHIFT EAST ACROSS THE SOUTH. MAXES WILL RANGE
FROM NEAR 60 NORTH TO MID 60S SOUTH. A LIGHT FREEZE IS STILL LIKELY
INLAND EARLY WED MORNING WITH THE RIDGE CENTER OVER N GA. TEMPS WILL
STILL LIKELY FALL INTO THE LOWER 30S WED NIGHT INLAND...BUT NNE
RETURN FLOW WILL DEVELOP WHICH MAY PRECLUDE A FREEZE.

THU THE AIRMASS MODIFIES AS THE RIDGE BUILDS OFFSHORE OF THE SE
ATLANTIC SEABOARD. TEMPS WARM INTO THE 70S INLAND WHILE A COOLER NE
FLOW KEEPS THE COST IN THE LOW 60S. A COASTAL TROUGH MAY BEGIN TO
DEVELOP THU NIGHT.

.LONG TERM...FRI THROUGH MON...
LOOKS LIKE THERE IS POTENTIAL FOR A HEAVY PRECIP EVENT LATE FRI INTO
SAT AS A WEAK MID LEVEL SFC LOW MOVE EASTWARD ACROSS THE GULF COAST
STATES. AS THE SYSTEM APPROACHES OUR AREA FRI AND BEGINS TO
STALL...A DEEPENING UPPER LEVEL TROUGH WILL PUT THE AREA IN THE
RIGHT-REAR QUAD OF THE UPPER JET AROUND THE TIME STRONG LOW LEVEL
ISENTROPIC LIFT WILL BE FOCUSING ACROSS OUR CWA. PRECIP CHANCES HAVE
BEEN CAPPED AROUND 40% AT THIS TIME..AND HIGH STABILITY INDICES
SHOULD PREVENT TS. SFC HIGH PRESSURE BUILDS IN FROM THE NW LATE
SAT...SHUNTING LOW LEVEL MOISTURE/PRECIP SOUTH OF OUR CWA WITH A
COOL NNE FLOW BRINGING MAXES DOWN IN THE 60S INLAND TO 50S COAST
WITH MINS IN THE MID 30S TO 40S TO START NEXT WEEK.

&&

.AVIATION...
MVFR CIGS/VSBYS WILL ACCOMPANY SQUALL LINE ALONG WITH GUSTY WINDS TO
35 KNOTS UNTIL SUNRISE. CLOUD SHIELD BEHIND SQUALL LINE MAY CONTAIN
