AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
236 PM EDT SAT MAR 31 2012

.SHORT TERM...NOW THROUGH TUESDAY...

REST OF THIS AFTERNOON/EVENING...NUMEROUS THUNDERSTORM ACTIVITY
AHEAD OF SHORTWAVE TROF HAS BASICALLY PUSHED OFFSHORE AND EXPECT THE
MORE SCATTERED VARIETY AS THE TROF AXIS PUSHES THROUGH THE REMAINDER
OF THE AFTERNOON AND EVENING HOURS. HAVE KEPT STRONG TSTM WORDING IN
THE ZFP/GRIDS FOR GUSTY WINDS...SMALL HAIL AND LOCALLY HEAVY
RAINFALL INTO THE EVENING HOURS.

OVERNIGHT...ONCE TROF AXIS CLEARS THE REGION BY MIDNIGHT ALL PCPN
WILL HAVE SHIFTED WELL OFFSHORE IN THE WRN ATLC AND EXPECT AREAS OF
FOG TO DEVELOP DUE TO COMBINATION OF MOIST GROUND CONDITIONS AND
LIGHT WESTERLY FLOW. MIN TEMPS REMAIN MILD IN THE UPPER 50S TO LOWER
60S.

SUNDAY...WEAK FRONTAL/TROF AXIS WILL PUSH THROUGH THE REGION FROM
NORTH TO SOUTH AND EXPECT DRIER AIRMASS TO SETTLE OVER THE REGION
WITH MOSTLY SUNNY SKIES AND MAX TEMPS THAT WILL PUSH INTO THE
MID/UPPER 80S.

MONDAY...MID LEVEL RIDGING WILL BUILD OVER THE REGION FROM THE WEST
AND ANOTHER WEAK SURFACE TROF WILL SLIDE SOUTHWARD JUST EAST OF THE
FORECAST AREA. AIRMASS WILL REMAIN RELATIVELY DRY WITH JUST SILENT
10% POPS DURING THE AFTERNOON HOURS AS TEMPS PUSH UPWARDS TO AROUND
90 DEGREES OVER SOME INLAND AREAS.

TUESDAY...SURFACE HIGH WILL SLIDE SOUTHEAST OF THE REGION AND LOW
LEVEL WINDS WILL TURN SOUTHERLY AND ATMOSPHERIC MOISTURE MAY
INCREASE ENOUGH TO TRIGGER ISOLATED SHOWERS AND THUNDERSTORMS DURING
THE AFTERNOON HOURS. MAX TEMPS STILL EXPECTED IN THE MID/UPPER 80S.

.LONG TERM...WEDNESDAY THROUGH SATURDAY...
A SERIES OF WEAK IMPULSES IN NORTHWEST FLOW AT THE MID/UPPER LEVELS
WILL PUSH ACROSS THE SERN U.S. AND THROUGH THE FORECAST AREA. DEEP
LAYER MOISTURE WILL BE LACKING BUT WILL BE ENOUGH TO TRIGGER MAINLY
AFTERNOON/EVENING ISOLATED SHOWERS AND THUNDERSTORMS WITH POPS IN
THE 20-30% RANGE. MAX TEMPS WILL GENERALLY REMAIN ABOVE NORMAL IN
THE 80S THROUGH THE PERIOD.

&&

.AVIATION...HAVE TEMPO THUNDER/IFR WITH GUSTY WINDS IN TAFS TIL 00Z
AS SHOWER ACTIVITY SHOULD CONTINUE THIS AFTERNOON AND THEN DIMINISH
EARLY THIS EVENING. PATCHY FOG POSSIBLE LATE TONIGHT WITH MVFR VSBYS

PRESSURE RE-BUILDS BACK ACROSS THE FLORIDA PENINSULA. A GENERAL
SOUTHWEST FLOW AT 10 TO 15 KNOTS OR LESS AND SEAS AT 2-3 FT OR LESS
WILL CONTINUE THROUGH MUCH OF NEXT WEEK.

RIP CURRENTS: LOW RISK WILL CONTINUE WITH OFFSHORE FLOW.

&&

.FIRE WEATHER...
NO HEADLINES EXPECTED THROUGH MONDAY ALTHOUGH MIN RH VALUES WILL
BOTTOM OUT BOTH SUNDAY/MONDAY AFTERNOONS AROUND 35 PERCENT. WINDS
WILL GENERALLY BE LIGHT ON SUNDAY AT 10 MPH OR LESS WHILE WEST WINDS
MAY INCREASE TO 10 TO 15 MPH ON MONDAY AFTERNOON AND THIS MAY BE
ENOUGH TO TRIGGER FIRE DANGER STATEMENTS ACROSS NE FL.

&&

.CLIMATE...
MARCH 2012 STILL ON TRACK TO GO DOWN AS THE WARMEST ON RECORD AT
ALMA AND ST SIMONS ISLAND ACROSS SE GA...WHILE BOTH GAINESVILLE AND
JACKSONVILLE WILL END UP RANKED SOMEWHERE BETWEEN 5 AND 10 WARMEST
