Severe Thunderstorm Warning 187, NWS Tallahassee, FL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
301 PM EDT THU JUL 14 2011

.SHORT TERM (TONIGHT THROUGH SATURDAY NIGHT)...THE RIDGE WHICH HAS
BEEN IN PLACE ACROSS THE REGION FOR SEVERAL DAYS IS FORECAST TO
SHIFT NORTHWEST THROUGH THE WEEKEND...ALLOWING HEIGHTS TO DECREASE
ACROSS THE FORECAST AREA. THIS SHIFT WILL ALLOW FOR SOME RELIEF TO
THE SWELTERING HEAT...AS WELL AS SPARK NUMEROUS AFTERNOON AND
EVENING SHOWERS AND THUNDERSTORMS. THE ADDITION OF A WEAK SURFACE
TROUGH FRIDAY ALONG THE I-10 CORRIDOR WILL FURTHER ENHANCE
CONVECTIVE COVERAGE ACROSS THE REGION...LEADING TO THE 70 PERCENT
POPS IN THE FORECAST.

THE SFC TROUGH IS FORECAST TO DISSIPATE BY SATURDAY. HOWEVER...
EASTERLY LOW LEVEL FLOW AND PWATS STILL WELL ABOVE 2 INCHES SHOULD
RESULT IN LIKELY COVERAGE FOR POPS OVER INLAND AREAS ONCE AGAIN.

SLIGHTLY COOLER TEMPERATURES ARE ON TAP FOR THE NEXT FEW DAYS WITH
HIGH TEMPERATURES IN THE UPPER 80S TO LOWER 90S VERSUS THE MID TO
UPPER 90S OVER THE LAST FEW DAYS.

.LONG TERM (SUNDAY THROUGH NEXT THURSDAY)... SECOND HALF OF THE
UPCOMING WEEKEND WILL FIND OUR FORECAST AREA IN BETWEEN A LARGE
AND DOMINANT AREA OF UPPER LEVEL RIDGING ACROSS THE CENTRAL
PLAINS/UPPER MIDWEST...AND ANOTHER UPPER RIDGE EAST OF THE BAHAMA
ISLANDS. GLOBAL GUIDANCE IN AGREEMENT THAT A MID-LEVEL
WEAKNESS/TROUGH WILL EXIST BETWEEN THESE TWO FEATURES ALONG THE
ATLANTIC SEABOARD TO THE NORTHEAST GULF OF MEXICO.

THE UPPER RIDGE ACROSS THE MID-SECTION OF THE COUNTRY IS LIKELY TO
GRAB HEADLINES THIS WEEKEND/EARLY NEXT WEEK AS ITS STRENGTH AND SIZE
RESULT IN A POTENTIALLY DANGEROUS HEAT WAVE FOR THAT REGION.

CLOSER TO HOME...UNDERNEATH THE MID-LEVEL WEAKNESS...OUR HEIGHTS
WILL BE MORE MODERATE...AND RESULT IN TEMPERATURES NEAR NORMAL FOR
MID SUMMER.

AT THE SURFACE...FLOW IS FORECAST TO COME AROUND MORE TO THE EAST
AND SOUTHEAST AS A LARGE RIDGE BUILDS OFF THE MID-ATLANTIC COAST AND
THEN ATTEMPTS TO RIDGE SOUTHWARD INTO THE CAROLINAS/GEORGIA.

RAIN (SHOWER/STORM) CHANCES STILL LOOK FAVORABLE DURING SUNDAY AS
ABUNDANT COLUMN MOISTURE IS FORECAST...ALONG WITH WEAK ADDED
SYNOPTIC SUPPORT FROM THE UPPER TROUGH. POP FORECAST IS A BIT MORE
TRICKY COME MONDAY AS THE GFS/ECMWF ARE BOTH SHOWING A WEAK SURFACE
REFLECTION/LOW TRYING TO ORGANIZE OFF THE GA COAST UNDER THE PARENT
MID-LEVEL ENERGY. DEPENDING ON THE STRENGTH/DEPTH OF THIS LOW...SOME
DRIER AIR WILL BE DRAWN SOUTHWARD AROUND THE BACKSIDE OF THE
CIRCULATION. BEST CHANCES TO SEE SOME CONVECTIVE SUPPRESSION FROM
THIS DRIER AIR WOULD BE ACROSS OUR NORTHERN ZONES (GA/AL). WILL KEEP
NEAR CLIMO RAIN CHANCES ALONG AND SOUTH OF THE I-10 CORRIDOR AND
THEN TAPER BELOW CLIMO FURTHER NORTH.

TUESDAY LOOKS TO BE A TRANSITION DAY IN THE SYNOPTIC PATTERN AS THE
UPPER RIDGE TO THE W/NW SLOWLY BEGINS TO REBUILD EASTWARD AND THE
SUBTROPICAL SURFACE RIDGE BEGINS TO RE-ESTABLISH ITSELF ACROSS THE
FLORIDA PENINSULA/EASTERN GULF. WILL LEAN THE FORECAST CLOSE TO
CLIMO IN TERMS OF BOTH TEMPERATURE AND RAIN CHANCES.

VERY GOOD AGREEMENT BETWEEN THE GLOBAL MODELS ON THE PATTERN FOR THE
MIDDLE PORTION (WED/THU) OF NEXT WEEK. UPPER RIDGE WILL BE BUILDING
IN FROM THE NORTHWEST WITH OUR HEIGHTS STEADILY CLIMBING. AT THE
SURFACE THE SUBTROPICAL RIDGE WILL BECOME FIRMLY IN CONTROL ONCE
AGAIN WITH ITS AXIS JUST TO OUR SOUTH. THE INCREASING SUPPRESSION
FROM THE BUILDING UPPER RIDGE ARGUES A TAPERING OF THE POPS DOWN
BELOW CLIMO AND AN INCREASE IN THE TEMPERATURES. IN FACT...IF THE
CURRENT FORECAST PATTERN WAS TO VERIFY...WE WOULD BE LOOKING AT SOME
HOT TEMPS FOR LATE JULY BY THE END OF THE FORECAST PERIOD.

&&

.AVIATION...SCATTERED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
ACROSS THE AREA. EXPECT STORMS TO CONTINUE INTO THE EVENING HOURS
BEFORE GRADUALLY DIMINISHING. A FEW AREAS OF MVFR VIS RESTRICTIONS
ARE POSSIBLE LATE TONIGHT WITH ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS LOOKING LIKELY FOR FRIDAY.

&&

.MARINE...A SURFACE TROUGH ALONG THE GULF COAST WILL WEAKEN INTO
THE WEEKEND AS HIGH PRESSURE NOSES DOWN THE EASTERN SEABOARD. THIS
WILL SHIFT WINDS FROM SOUTHWESTERLY TO EASTERLY BY SATURDAY INTO
EARLY NEXT WEEK. WINDS ARE SEAS ARE FORECAST TO REMAIN BELOW
HEADLINE CRITERIA.

&&

.FIRE WEATHER...ABUNDANT LOW LEVEL MOISTURE WILL KEEP RELATIVE
HUMIDITY VALUES WELL ABOVE CRITICAL LEVELS THROUGH THE FORECAST
PERIOD. SHOWERS AND THUNDERSTORMS WITH WET FLAGS APPEAR LIKELY FOR
FRIDAY.

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...

...THERE IS A MODERATE RISK OF RIP CURRENTS TODAY AND FRIDAY
ALONG THE BEACHES OF THE FLORIDA PANHANDLE...

A LONG FETCH OF SOUTHWESTERLY WINDS OFF THE GULF OF MEXICO WILL
CREATE SWELLS...WHICH WILL COMBINE WITH THE WIND WAVES TO PRODUCE
MORE FREQUENT RIP CURRENTS ALONG THE BEACHES OF THE FLORIDA
PANHANDLE TODAY AND FRIDAY. ALSO...SCATTERED YO NUMEROUS SHOWERS
AND THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THE SEA BREEZE
TODAY. SOME OF THESE STORMS COULD PRODUCE BRIEF GUSTY WINDS...
FREQUENT LIGHTNING...AND TORRENTIAL DOWNPOURS. THESE SHOWERS AND
STORMS COULD LINGER WELL INTO THE EVENING HOURS TONIGHT.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
AS THE UPPER LEVEL RIDGE OF HIGH PRESSURE CONTINUES TO BUILD
FURTHER OFF TO OUR NORTHWEST...A TROUGH OF LOW PRESSURE WILL BEGIN
TO DEVELOP OVER THE SOUTHEASTERN U.S.. THIS WILL LEAD TO HIGHER
RAIN CHANCES AND LOWER AFTERNOON HIGH TEMPERATURES FOR THE TRI-STATE
REGION FOR THE END OF THE WEEK AND THE UPCOMING WEEKEND. HIGH
PRESSURE WILL BEGIN TO BUILD BACK INTO THE AREA DURING THE EARLY
TO MIDDLE PORTIONS OF NEXT WEEK...RETURNING RAIN CHANCES BACK TO
NORMAL OR BELOW NORMAL...AND HIGH TEMPERATURES BACK TO WELL ABOVE
NORMAL. ALTHOUGH SOME STORMS COULD BE STRONG ON ANY GIVEN
AFTERNOON...NO WIDESPREAD SEVERE WEATHER IS EXPECTED AT THIS TIME.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.
