AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
320 PM EDT MON AUG 22 2011

.SYNOPSIS...18 UTC SURFACE ANALYSIS SHOWS A COLD FRONT MOVING
THROUGH THE SOUTHEAST. THE BOUNDARY IS ANALYZED JUST SOUTH OF I-20
ACROSS MIDDLE GEORGIA INTO MID STATE SOUTH CAROLINA. OUT AHEAD OF
THIS BOUNDARY WAS A WEAK CONFLUENCE ZONE...ROUGHLY ACROSS OUR
NORTHERN COUNTIES. IT IS IN THIS AREA THAT SCATTERED SHOWERS AND
THUNDERSTORMS ARE DEVELOPING. SURPRISINGLY...THE SEA BREEZE FRONT
TODAY HAS NOT BEEN VERY ACTIVE...DESPITE THE ENHANCED CONVERGENCE.
IT APPEARS THAT THE DRIER AIR ALOFT IS WINNING OUT...BASED ON OUR
18Z SOUNDING WHICH IS SHOWING NOT ONLY DRYING ALOFT BUT WARMER
TEMPERATURES IN THE 500-300 MB LAYER.

&&

.SHORT TERM...(TONIGHT THROUGH WEDNESDAY NIGHT).
OVERALL...THE SHORT TERM MODELS ARE IN PRETTY GOOD AGREEMENT THAT
THE SURFACE BOUNDARY WILL DROP TOWARD THE GULF COAST THIS EVENING
BEFORE STALLING AND DISSIPATING. DRIER AIR ALOFT WILL CONTINUE TO
RESULT IN LESS RAINFALL CHANCES THROUGHOUT THE SHORT TERM PERIOD.
GRADUALLY INCREASING MOISTURE FROM THE EAST ON WEDNESDAY WILL LIKELY
LEAD TO A SLIGHT ENHANCEMENT IN RAIN CHANCES FOR THE EASTERN AREA IN
MODERATE EASTERLY FLOW.

TEMPERATURES THROUGHOUT THE PERIOD WILL CONTINUE TO BE WARM...TEMPS
GENERALLY PEAKING IN THE MID TO UPPER 90S ACROSS THE REGION.
GENERALLY STAYED A COUPLE DEGREES ABOVE GUIDANCE THROUGHOUT THE
PERIOD AS LESSER RAIN CHANCES SHOULD SUPPORT BETTER AFTERNOON
HEATING.

&&

.LONG TERM...(THURSDAY THROUGH NEXT MONDAY).

UPDATED LONG TERM DISCUSSION...3 PM ET.

THE LATEST NATIONAL HURRICANE CENTER FORECAST FOR IRENE HAS
CONTINUED TO SHIFT EASTWARD THROUGHOUT THE DAY. THIS TREND IS ALSO
APPARENT IN MOST OF THE GUIDANCE MEMBERS. THIS EASTWARD SHIFT WOULD
RESULT IN LIGHTER WINDS ACROSS THE FORECAST AREA. AS A
RESULT...ADJUSTED THE WIND GRIDS DOWN SLIGHTLY THROUGHOUT THE
EXTENDED PERIOD TO MATCH WITH THE LATEST FORECAST. OF COURSE...WE
WILL NEED TO CONTINUE TO WATCH IRENE CLOSELY...AS FEATURES JUST NOW
MOVING INTO THE WESTERN CONUS WILL BE AFFECTING ITS NORTHWARD TURN
LATER THIS WEEK. STAY TUNED AND CONTINUE TO MONITOR THE LATEST
FORECASTS FROM THE NATIONAL HURRICANE CENTER.

PREVIOUS OVERNIGHT LONG TERM DISCUSSION FROM 330 AM ET BELOW.

THE FOCUS FOR THE LONG TERM CONTINUES TO BE ON IRENE AND WHAT
EFFECTS...IF ANY...IT WILL HAVE ON THE LOCAL AREA. AS IRENE
APPROACHES THE SOUTHEAST U.S. BY THE END OF THE WEEK...THE UPPER
LEVEL PATTERN IS FORECAST TO BE SETUP WITH RIDGING OVER THE WESTERN
STATES AND TROUGHING OVER THE GREAT LAKES REGION WITH A SUBTROPICAL
RIDGE OVER THE WESTERN ATLANTIC. THE TROUGHING OVER THE GREAT LAKES
IS EXPECTED TO PROVIDE A BREAK IN BETWEEN THE ATLANTIC SUBTROPICAL
RIDGE AND THE RIDGE OVER THE WESTERN STATES THAT WILL PLAY AN
IMPORTANT ROLE IN THE FUTURE PATH OF IRENE.  THE BIGGER THAT BREAK
IS IN BETWEEN THE TWO RIDGES...THE MORE LIKELY IT BECOMES THAT IRENE
WILL TURN NORTHWARD AT AN EARLIER TIME AND REMAIN EAST OF THE LOCAL
AREA. HOWEVER...IF THE TROUGH TURNS OUT TO BE WEAKER AND RIDGING
BUILDS BACK IN MORE QUICKLY NORTH OF THE STORM...THEN IT BECOMES
MORE LIKELY THAT IRENE WILL CONTINUE WESTWARD FOR A LONGER PERIOD OF
TIME.

MODEL SOLUTIONS OVER THE LAST COUPLE OF DAYS HAVE STARTED TO
CONVERGE ON A MORE EASTWARD TRACK TO THE EAST OF THE FORECAST AREA
NEAR THE EAST COAST OF FLORIDA...AND THE OFFICIAL NHC FORECAST
AGREES. IF THE EASTWARD TRACK VERIFIES...SOME BREEZY NORTHERLY WINDS
AND AN INCREASED CHANCE OF RAIN WOULD OCCUR ACROSS THE EASTERN PARTS
OF THE FORECAST AREA...BUT THE MAJOR IMPACTS WOULD STAY EAST OF THE
AREA. A COUPLE OF MODELS SUCH AS THE 22/00Z UKMET AND 22/00Z GFDL
ARE STILL FARTHER TO THE WEST...BUT THEY ARE CONSIDERED OUTLIERS AND
LESS LIKELY SOLUTIONS AT THE MOMENT.

AT THIS STAGE...IT IS IMPORTANT TO REMEMBER THAT THE DAY 5 TROPICAL
CYCLONE FORECASTS CARRY A 5 YEAR AVERAGE TRACK ERROR OF AROUND 250
MILES AND A 5 YEAR AVERAGE INTENSITY ERROR OF AROUND 20 KNOTS.
THEREFORE...EVEN THOUGH THE CONSENSUS OF THE GUIDANCE IS NOT SHOWING
A MAJOR IMPACT FOR OUR FORECAST AREA AT THIS TIME...IT REMAINS A
GOOD IDEA TO CONTINUE MONITORING THE SYSTEM CLOSELY AS A WESTWARD
SHIFT IN TRACK WOULD INCREASE THE THREAT LOCALLY. PLEASE REFER TO
THE NHC ADVISORIES FOR THE LATEST INFORMATION ON THE FORECAST TRACK
AND INTENSITY OF IRENE.

&&

.MARINE...EXPECT LIGHT WINDS AND LOW SEAS FOR THE BALANCE OF THE
SHORT TERM PERIOD. AS IRENE APPROACHES THE SOUTHEAST U.S.
COAST...THE PRESSURE GRADIENT WILL TIGHTEN. BASED ON THE LATEST
FORECAST...WINDS ARE EXPECTED TO APPROACH LOW-END ADVISORY LEVELS
THURSDAY NIGHT INTO FRIDAY...PRIMARILY ACROSS THE EASTERN LEGS. IF
IRENE MOVES CLOSER THAN EXPECTED...THE WINDS WILL BE STRONGER THAN
CURRENTLY INDICATED IN THE FORECAST. ALL INTERESTS IN THE EASTERN
GULF OF MEXICO...SHOULD KEEP UP TO DATE WITH THE LATEST FORECASTS
CONCERNING IRENE.

&&

.AVIATION...THUNDERSTORMS BEGINNING TO DEVELOP PER AREA RADARS AND
VISIBLE SATELLITE IN A WEAK CONVERGENCE ZONE FROM SRN AL INTO S/C
GA...APPROXIMATELY 10-20 MI NORTH OF THE ABY AND DHN TERMINALS.
SHORT RANGE MODEL GUIDANCE AND ENSEMBLES SUGGEST THAT THIS ACTIVITY
WILL CONTINUE TO DEVELOP AND IMPACT ABY AND DHN EARLY-MID AFTN.
THEREFORE...A TEMPO GROUP WAS INTRODUCED AT BOTH THOSE TERMINALS.
BEST CHC FOR TSTMS OUTSIDE OF THOSE AREAS LOOKS TO BE AT TLH. WENT
WITH A TEMPO GROUP THERE...WITH ONLY A CB MENTION AT VLD AND ECP.
THERE COULD BE SOME LOCALIZED GUSTY WINDS WITH ANY STRONGER STORM.
CONFIDENCE IN FOG POTENTIAL TONIGHT IS LOW...ESPECIALLY WITH DRIER
AIR MASS BEGINNING TO WORK INTO THE AREA AFTER 09Z. HINTED AT SOME
6SM VSBYS WITH BR AT TLH...ECP...AND VLD BETWEEN 10Z AND 13Z...BUT
DID NOT INTRODUCE ANY MVFR RESTRICTIONS FOR NOW.

&&

.FIRE WEATHER...NO CRITICAL CONDITIONS ARE EXPECTED IN THE
FORESEEABLE FUTURE. DRIER AIR MASS ARRIVING TOMORROW SHOULD DROP MIN
RH VALUES IN ALABAMA ZONES AND FAR SW GEORGIA ZONES CLOSE TO THE
30-35 PERCENT RANGE. HOWEVER...THE RH VALUES SHOULD ONLY APPROACH
CRITICAL THRESHOLDS FOR AN HOUR OR SO. COMBINED WITH LIGHT WINDS
THIS SHOULD KEEP ALL OF OUR AREAS OUT OF RED FLAG CONCERNS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST ALABAMA...
SOUTHWEST AND SOUTH CENTRAL GEORGIA...AND THE FLORIDA BIG BEND
AND PANHANDLE...AND ADJACENT COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT...
THE LOCAL AREA REMAINS BETWEEN A COLD FRONT OVER NORTH CENTRAL
GEORGIA AND WEAK HIGH PRESSURE OVER THE GULF OF MEXICO. DURING THE
DAY...THIS FRONT WILL DROP SOUTH AND ACROSS THE LOCAL AREA REACHING
THE COAST LATE TONIGHT. THE COMBINATION OF THIS FRONT...RELATED
OUTFLOW BOUNDARIES...SEA BREEZES AND A PASSING UPPER DISTURBANCE
SHOULD GENERATE SCATTERED TO NUMEROUS SHOWERS AND STORMS. SOME OF
THESE STORMS COULD BECOME STRONG WITH GUSTY WINDS AND HEAVY RAINS
AND WE CAN NOT DISCOUNT AN ISOLATED SEVERE STORM. RAIN WILL END
FORM NORTHWEST TO SOUTHEAST TONIGHT.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY...
RAIN CHANCES WILL DECREASE TUESDAY THROUGH THURSDAY AS HIGH PRESSURE
BUILDS IN OVER THE LOCAL AREA. THE FORECAST ON FRIDAY AND BEYOND IS
HIGHLY DEPENDENT ON THE TRACK OF IRENE. CURRENTLY...ABOVE AVERAGE
RAIN CHANCES AND BREEZY CONDITIONS ARE ADVERTISED. HOWEVER...
CONFIDENCE IS VERY LOW WITH RESPECT TO WHAT...IF ANY EFFECTS WILL BE
FELT ACROSS OUR LOCAL AREA.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED.
