Hail and Damaging Wind in Georgia, July 1 to 2, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
245 PM EDT FRI JUL 1 2011

.SYNOPSIS...
AT 240 PM EDT...RADAR INDICATED THAT GULF SEA BREEZE DRIFTING NWD
ACROSS FL COASTAL PANHANDLE WITH WIDELY SCT CONVECTION DEVELOPING.

AT UPPER LEVELS...
THE LARGE SCALE LONGWAVE PATTERN REMAINS AMPLIFIED...ESPECIALLY EAST
OF ROCKIES. THIS IS HIGHLIGHTED BY VERY WEAK TROUGHING OVER WRN
STATES...WELL AMPLIFIED RIDGE FROM PLAINS TO GREAT LAKES WITH HIGH
PRESSURE CENTERED OVER ARK...AND H5 TROUGH FROM CANADIAN MARITIMES
SSW AND DRIFTING SWD ACROSS NE FL. SATELLITE IMAGES CONTINUE TO SHOW
DRYING OVERSPREADING THE CWA FROM NE-SW...WITH PWAT VALUES BELOW
CLIMATOLOGY. THIS REFLECTED IN LOCAL VAD PROFILES. I.E. TLH WITH
LIGHT NE WINDS SFC-15K. SO FORECAST AREA BECOMING INCREASINGLY
INFLUENCED BY RIDGING ALOFT...WHICH TYPICALLY MEANS DRIER AND HOTTER
WEATHER.

DURING THE SHORT TERM...THE STRONG RIDGE OVER THE CENTRAL U.S. WILL
BUILDING EAST WITH NRN PART INTO NEW ENGLAND ON SAT WHILE 1000-500
MB RIDGE BUILDS DOWN FROM THERE CONTINUING TO SET UP A DRIER NNE
FLOW AND SUBSIDENCE TO FILTER SWD OVER THE LOCAL AREA. THIS WILL
PUSH EAST COAST TROUGH INTO THE EXTREME WRN ATLC LATER TODAY. IN
FACT...UPPER LEVEL RIDGING WILL PROBABLY BE AT ITS PEAK OVER OUR
REGION SATURDAY WITH THE LOWEST POPS AND HIGHEST TEMPS. HOWEVER...BY
SUNDAY THE UPPER RIDGE WILL BEGIN TO RETROGRADE...AND GUIDANCE
CONSENSUS IS FOR A MODEST INCREASE IN DEEP LAYER MOISTURE WITH RAIN
CHANCES TO BEGIN A CLIMB BACK TOWARD CLIMATOLOGY SUNDAY AND INTO
JULY 4TH. THIS REFLECTED IN MODEL SOUNDINGS. I.E. GFS TAE WITH 1.37
INCH PWAT AT 18Z FRI DECREASING TO 1.0 INCH PWAT AT 18Z SUN BEFORE
RISING BACK TO 1.51 INCH BY 06Z MON.

AT LOWER LEVELS...
ANALYSIS SHOWED A QUASI-STATIONARY FRONT FROM THE PIEDMONT THROUGH
THE FL PANHANDLE WITH A MESO HIGH THAT DEVELOPED YESTERDAY OVER
SOUTHWEST GA. HIGH PRESSURE EXISTS OVER THE NORTHEAST GULF AND
SOUTHEAST STATES. ALSO...MCS/MCV IMPACTING N CNTRL GA/AL THIS AFTN.
THE GULF RIDGE AXIS WILL DRIFT NORTH INTO N FL OVER THE WEEKEND WITH
FLOW VEERING TO MORE ESE ACROSS THE AREA. DRIER AIR ESPECIALLY ABOVE
LOWER LEVELS WILL PROMOTE THE DEVELOPMENT OF PATCHY TO AREAS OF FOG
ACROSS SOME OF AREA EACH NIGHT.

MODELS BRING A STRONG SHORTWAVE THROUGH THE NE FLOW ON SATURDAY
WHICH HELPS ESTABLISH A FAIRLY PRONOUNCED FRONT/TROUGH ACROSS
N/CENTRAL GA SAT THROUGH SUNDAY. ON SUN AND ESPECIALLY ON JULY 4TH
PRECIP CHANCES INCREASE SLIGHTLY AS THIS WEAKENING FRONT APPROACHES
FROM THE NW.

&&

.SHORT TERM...(TONIGHT THROUGH MONDAY)
TONIGHT...ABOVE MCS MOVING GENERALLY SSE AROUND 15 MPH. NEW NAM HAS
COME INTO AGREEMENT WITH WRF 4KM AND ARW WHICH SHOW REMNANTS OF MCS
DROPPING DOWN ACROSS SE ALA DURING EVE AND CONTINUING TO WRN
PANHANDLE COAST THRU 12Z. CONVERSELY...GFS MUCH WEAKER SIGNAL
KEEPING MCS REMNANTS IN SE SE AL. IN BOTH CASES...ANY STRONG WEATHER
THREAT DECREASES WITH TIME. HIGHER POPS WRN SITES REFLECTED IN NEW
NAM GUIDANCE I.E. DHN WITH 30% AND ABY WITH 25% POPS. CONVERSELY...
GFS POPS REMAIN VERY LOW. WILL GO 40% SE AL/ADJACENT SW GA...30%
REST OF SW GA AND FL PANHANDLE (FOR EVE GULF SEABREEZE AND ANY LATE
MCS ACTIVITY) AND BIG BEND (LATTER TO ACCOUNT FOR LATE EAST COAST
SEA BREEZE AND ANY ENHANCEMENT FROM DEPARTING UPPER TROUGH) AND 20%
POPS ELSEWHERE. WITH VERY LIGHT STEERING FLOW...ANY SEABREEZE/
OUTFLOW/MCS INTERACTIONS COULD PRODUCE BRIEF HEAVY RAIN. OTHERWISE
...DRIER AIR WILL FILTER IN ACROSS MUCH OF THE AREA FROM NE-SW WITH
CONDITIONS FAVORABLE FOR AREAS OF LIGHT FOG DEVELOPMENT ESPECIALLY
ERN COUNTIES. LOWS NEAR NEAR 70 SE BIG BEND...LOW 70S REST OF
INLAND...LOW-MID 70S COAST.

SATURDAY...WITH DRIER AIR FURTHER ENCROACHING SWWD...WILL GO WITH
10-20% E-W POP GRADIENT. WITH THE NELY STEERING FLOW...EXPECTED LATE
START TO THE THUNDERSTORMS AND THEIR OVERALL DECREASE IN COVERAGE
AND FOCUS NEAR COAST WILL ALLOW INLAND TEMPERATURES TO APPROACH THE
CENTURY MARK IN AFTN ESPECIALLY IN THE NORMALLY WARMER LOCATIONS OF
SE AL/SW GA/INLAND FL PANHANDLE. THERE SHOULD BE ENOUGH DRYING AT
THE SURFACE TO PREVENT HEAT INDEX VALUES FROM REACHING THE DANGEROUS
105 DEGREE LEVEL...BUT THEY COULD GET CLOSE EACH AFTERNOON IN THE FL
PANHANDLE. NIL POPS SAT NIGHT WITH LOWS FROM UPPER 60S SE BIG
BEND...LOW 70S REST OF INLAND...LOW-MID 70S COAST. PATCHY LIGHT FOG
AGAIN POSSIBLE.

SUNDAY...20% POPS WITH HIGHS AROUND 90 COAST...MID-UPPER 90S
ELSEWHERE. NIL POPS AT NIGHT. LOWS NEAR NEAR 70 SE BIG BEND...LOW
70S REST OF INLAND...LOW-MID 70S COAST. PATCHY LIGHT FOG LIKELY
LATE.

MONDAY...30% POPS. HIGHS AROUND 90 COAST TO MID 90S INLAND.

&&

.LONG TERM...(MON NIGHT THROUGH NEXT FRIDAY)
A RETROGRESSION OF THE LARGE SCALE PATTERN ACROSS THE CONUS WILL BE
UNDERWAY AT THE BEGINNING OF THE PERIOD...AS THE BROAD UPPER LEVEL
RIDGE...EXTENDING FROM THE SOUTHWEST U.S. ACROSS THE SOUTHEAST...
BEGINS TO SHIFT WESTWARD...ALLOWING A SERIES OF SHORT WAVES TO CARVE
OUT A NEW MEAN TROUGH ACROSS THE EASTERN U.S. SUPPORTED BY A
DEEPENING UPPER LOW OVER THE HUDSON BAY. FOR THE TRI-STATE AREA THIS
WILL MEAN A GRADUAL TREND BACK TOWARD INCREASING MOISTURE WITH MORE
CLOUDS AND SOMEWHAT HIGHER POPS...ENHANCED BY THE SEA BREEZE...
STARTING AROUND THE MIDDLE OF THE WEEK...AND A CORRESPONDING SLIGHT
DOWNWARD SHIFT IN TEMPERATURES THROUGH THE END OF THE WEEK...ALSO
THE DOOR WILL BE OPEN AGAIN FOR POSSIBLE IMPACTS FROM WEAKENING
MCS'S AS THEY MOVE DOWN THE EAST SIDE OF THE RIDGE....BUT THIS IS
WILL BE A WILD CARD FROM DAY TO DAY AS WE APPROACH THE END OF THE
WEEK. ANOTHER POTENTIAL FACTOR IS AN EASTERLY WAVE THAT THE MODELS
HAVE BEEN HINTING WILL BE APPROACHING FLORIDA AND THE EASTERN GULF
BY THE END OF THE WEEK. THE OLD EURO SHOWS A SIGNIFICANT INCREASE IN
DEEP LAYER MOISTURE WHILE THE NEW GFS DOWNPLAYS THIS FEATURE. WILL
USE A BLEND WITH A LITTLE HIGHER WEIGHT TOWARD THE GFS AT THE
BEGINNING AND A LITTLE MORE WEIGHT TOWARD THE EURO AT THE END. POPS
WILL TREND UPWARD TOWARDS CLIMATOLOGY WHILE MAX TEMPERATURES WILL
REMAIN A LITTLE ABOVE NORMAL.

&&

.MARINE...
LINGERING EFFECTS OF ABOVE MCS MAY GENERATE SMALL CHANCE OF
CONVECTION WRN NEARSHORE WATERS TOWARDS SUNRISE. OTHERWISE...EXCEPT
FOR THE USUAL INCREASE IN WINDS AND SEAS NEAR THE COAST SAT AFTN...
WINDS AND SEAS WILL GENERALLY REMAIN AT TYPICALLY LOW SUMMERTIME
LEVELS. THE LATEST GUIDANCE AND UPSTREAM BUOY OBS DO NOT SHOW MUCH
BUMP FROM WHAT WAS TROPICAL STORM ARLENE. THIS SHOULD PREVENT A
SIGNIFICANT RIP CURRENT THREAT.

&&

.AVIATION...AFTER THE PATCHY MORNING FOG (WHICH IMPACTED THE VLD AND
ABY TERMINALS) QUICKLY BURNED OFF...SKIES BECAME MOSTLY CLEAR
ALLOWING THE HOT TEMPERATURES TO RETURN TO THE REGION. AS OF 100 PM
EDT...ALL OF THE TAF SITES HAD EXCEEDED THE 90 DEGREE MARK...AND ARE
WELL ON THEIR WAY INTO THE MIDDLE AND UPPER 90S. ALSO...THE SEA
BREEZE IS JUST BEGINNING TO DEVELOP AND WILL SLOWLY PUSH INLAND
THROUGH THE REST OF THE DAY...WHILE GRADUALLY BECOMING MORE
CONVECTIVELY ACTIVE. FURTHERMORE...AN OLD SFC TROF WHICH IS STILL
LINGERING IN OUR VICINITY MAY HELP FIRE OFF ADDITIONAL SHOWERS AND
STORMS WHICH WILL CREATE NEW OUTFLOW BOUNDARY MERGERS TO SPAWN NEW
CONVECTION. AS IF THAT WERE NOT ENOUGH...THERE ARE INCREASINGLY
STRONG SIGNALS IN THE NAM12 AND HI-RES 4KM WRF SUITES OF POTENTIAL
MCS DEVELOPMENT ACROSS SOUTHEAST ALABAMA TOWARDS 00 UTC.
THEREFORE...HAVE PLACED A MORE PESSIMISTIC CONVECTIVE TEMPO FOR DHN
WHICH TAKES THEM DOWN TO A PERIOD OF IFR CONDITIONS. ALSO PLACED
TEMPOS FOR SHOWERS AND STORMS AT ECP AND TLH...BUT ARE LEAVING VCTS
AND SCT CB GROUPS AT ABY AND VLD FOR THE TIME BEING AS THE HIGHEST
POPS ARE STILL TO THE WEST (ALTHOUGH AMENDMENTS FOR SHOWERS AND
STORMS CANNOT BE RULED. FOR THE OVERNIGHT HOURS...EXPECT PREVAILING
VFR CONDITIONS TO CONTINUE WITH JUST SOME MINOR MVFR RESTRICTIONS AT
DHN (DUE TO THE POTENTIAL HIGH QPF)...AND ABY AND VLD (DUE TO
PERSISTENCE).

&&

.FIRE WEATHER...ALTHOUGH ANOTHER STRETCH OF HOT WEATHER AND
GENERALLY DRY WEATHER IS IN STORE FOR OUR REGION THROUGHOUT THE
HOLIDAY WEEKEND...IT SHOULD BE SUFFICIENTLY HUMID TO DETER AND FIRE
WEATHER CONCERNS. ONLY FAR INLAND PORTIONS OF THE FL BIG BEND AND
PANHANDLE MAY EXPERIENCE 1 OR 2 HOURS OF RELATIVE HUMIDITY BELOW 35
PERCENT AT BEST. ADDITIONALLY...ERC LEVELS ARE FORECAST TO BE BELOW
35 OVER ALL OF OUR FLORIDA COUNTIES...AND ALTHOUGH MIXING HEIGHTS
WILL BE QUITE HIGH...LOW TRANSPORT WIND SPEEDS SHOULD KEEP
DISPERSIONS BELOW 75.

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...
SCATTERED AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED
TODAY...WITH THE GREATEST CHANCE OF RAIN ACROSS FLORIDA WHERE THE
SEA BREEZE FRONTS WILL BE MOST ACTIVE. IT DOES NOT APPEAR THAT THE
ATMOSPHERE WILL BE QUITE AS UNSTABLE TODAY AS IT HAS BEEN
RECENTLY...SO WIDESPREAD SEVERE STORMS ARE UNLIKELY. HOWEVER...A
BRIEF SEVERE STORM OR TWO IS ALMOST ALWAYS POSSIBLE IN THE
SUMMERTIME. THE HEAT INDEX WILL APPROACH 105 DEGREES AT SOME
LOCATIONS THIS AFTERNOON.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY...
NO ORGANIZED SEVERE WEATHER IS EXPECTED.

.SPOTTER INFORMATION STATEMENT...
WIDESPREAD SPOTTER ACTIVATION WILL NOT BE NEEDED.
