Severe Thunderstorm Warning 191, NWS Tallahassee, FL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
330 PM EDT THU JUN 22 2006

.SYNOPSIS...
H5 PATTERN ACROSS CONUS SHOWING NEARLY ZONAL NORTHERN STREAM FLOW
WITH THE EXCEPTION OF SHORTWAVE PUSHING THROUGH MIDDLE MISSISSIPPI
VALLEY. SOUTH OF THIS FEATURE UPPER LEVEL RIDGE CONTINUES TO HAVE
CONTROL OVER MUCH OF THE GULF COAST AND SOUTHEASTERN STATES.
GUIDANCE IN AGREEMENT OF SLOW AMPLIFICATION TO THE PATTERN OVER THE
FIRST PART OF THE WEEKEND TO A WEST COAST RIDGE...EAST COAST TROUGH
CONFIGURATION. WITH THE DIGGING TROUGH IN THE EAST...A WEAK BOUNDARY
IS SHOWN PUSHING INTO THE SOUTHEAST AND THEN STALLING. GUIDANCE NOT
IN GOOD AGREEMENT WITH REGARDS TO UPPER LOW NORTH OF THE BAHAMAS.
NAM IS THE MOST BULLISH WITH THIS FEATURE BRINGING A CLOSED SURFACE
LOW INTO THE EASTERN FLORIDA PENINSULA EARLY SATURDAY. THE GFS IS
MUCH WEAKER WITH THIS SYSTEM AND HAS TROUBLE EVEN HOLDING ON TO A
SURFACE TROUGH AS IT CROSSES THE PENINSULA. AT THIS TIME...WILL BE
LEANING MUCH MORE TOWARD THE GFS SOLUTION AS NAM IS ALSO SHOWING YET
ANOTHER SIGNIFICANT SYSTEM MOVING NORTH OF THE BAHAMAS TOWARD THE
CAROLINA COAST BY LATER SUNDAY.

&&

.SHORT TERM (TONIGHT THROUGH SUNDAY)...
STILL EXPECTING ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS THE AREAS FOR THE AFTERNOON AND AT LEAST EARLY EVENING HOURS.
ALREADY AS OF 18Z HAVE SEEN SOME ISOLATED CONVECTION ACROSS OUR GA
ZONES...VERY NEAR TO KVLD. CONVECTION ASSOCIATED WITH THE WEAK
SURFACE TROUGH IN GA LAST NIGHT WAS ABLE TO HOLD TOGETHER WELL INTO
THE LATE EVENING...AND WOULD NOT BE SURPRISED TO SEE SHOWERS AND A
FEW THUNDERSTORMS LASTING AGAIN FOR A FEW HOURS PAST SUNSET.

ON FRIDAY...THE NEXT WEAK FRONT WILL BEGIN TO EDGE DOWN INTO THE
SOUTHEAST VERY LATE IN THE DAY. BESIDES THIS FEATURE WILL BE LOOKING
AT A SIMILAR LOW LEVEL FLOW AS WE SEE TODAY WITH A 10KT NE FLOW
(TYPE 2 REGIME). KEEPING WITH THE GFS THINKING...THE SYSTEM CLOSE TO
THE BAHAMAS WILL STILL BE OFFSHORE OF THE FLORIDA EAST COAST FRIDAY
AFTERNOON AND EVENING. THE GFS ALSO IS SHOWING A DRY TONGUE CROSSING
OUR EASTERN ZONES DURING THE AFTERNOON AND EVENING. WITH THIS IN
MIND BEST CHANCE FOR SCATTERED CONVECTION SEEM TO BE ACROSS CENTRAL
AND WESTERN ZONES CLOSER TO BEST MOISTURE AND SURFACE TROUGH TO THE
NORTHWEST. TEMPERATURES WILL AGAIN HAVE THE POTENTIAL TO REACH THE
MIDDLE AND UPPER 90S IN LOCATIONS THAT FAIL TO RAIN THROUGH MID
AFTERNOON.

SATURDAY INTO SUNDAY THE FRONT LOOKS TO BASICALLY STALL ACROSS OUR
FAR WESTERN AND NORTHERN ZONES. LOOKING FOR A CONTINUATION OF
ISOLATED TO SCATTERED CONVECTION WITH THIS FEATURE AND WITH
AFTERNOON SEA-BREEZE FORMATION. WITH GUIDANCE NOT IS GOOD AGREEMENT
WITH SURFACE WAVE ACROSS CENTRAL FLORIDA PENINSULA AT THIS
TIME...AVAILABLE MOISTURE IN IN QUESTION AND AM HESITANT TO RAISE
POPS AT THIS TIME.

&&

.LONG TERM...
THE GFS SHOWS AN UPPER LOW REACHING THE GREAT LAKES MONDAY
THROUGH TUESDAY BEFORE DISSIPATING. ANOTHER CLOSED LOW DEVELOPS OVER
THE OHIO VALLEY ON WEDNESDAY. THE RESULT WILL BE A DEEPENING AND
PERSISTENT LONG WAVE TROUGH OVER THE EASTERN CONUS THROUGH THE
PERIOD AND THE PRESENCE OF A WEAK AND MEANDERING FRONTAL BOUNDARY
ACROSS THE SOUTHEAST CORNER OF THE U.S. THIS ALONE SHOULD PROVIDE AN
UNSETTLED WEATHER PATTERN WITH INCREASING PROSPECTS OR SHOWERS AND
THUNDERSTORMS. THEN...THERE IS THE UNCERTAINTY OF THE FUTURE TRACK
AND INTENSITY OF THE TROPICAL SYSTEM MENTIONED ABOVE. THIS WILL ALL
DEPEND ON THE STRENGTH AND POSITION OF THE UPPER TROUGH. IF THE LOW
CROSSES THE PENINSULA AND EMERGES INTO THE EASTERN GULF...POPS WILL
INCREASE SIGNIFICANTLY OVER THE CURRENT LOW TO MID RANGE CHANCE
CATEGORY. TEMPS WILL RETURN NEAR CLIMO THROUGH THE FORECAST PERIOD.

&&

.MARINE...
WEAK PRESSURE GRADIENT WILL KEEP WINDS GENERALLY LIGHT AND SEAS LOW
THROUGH MUCH OF THE UPCOMING WEEKEND...WITH ENHANCEMENT OF ONSHORE
WINDS DURING EACH AFTERNOON CLOSE TO THE COAST. SURFACE TROUGH LATER
IN THE WEEKEND IS FORECAST TO CROSS THE FLORIDA PENINSULA INTO THE
EASTERN GULF AT THIS TIME LOOKS TO REMAIN WEAK AND SHOULD ONLY BRING
AN INCREASED CHANCE OF SCATTERED SHOWERS AND THUNDERSTORMS FOR THE
BEGINNING OF NEXT WEEK.

&&

.AVIATION...
VFR CONDITIONS ARE EXPECTED FOR THE REMAINDER OF TODAY. ISOLATED
THUNDERSTORMS MAY DEVELOP THIS AFTERNOON...BUT PROBABILITIES REMAIN
LOW ENOUGH TO LEAVE OUT OF THE TAFS. BRIEF IFR-MVFR CEILINGS AND
VISIBILITY...AS WELL AS WIND GUSTS TO 25 KT...CAN OCCUR IN THESE
STORMS. OTHERWISE...THE VFR CONDITIONS WILL CONTINUE OVERNIGHT AND
INTO FRIDAY FOR MOST OF THE REGION...THOUGH MVFR VISIBILITIES ARE
POSSIBLE AT TLH AND VLD IN THE EARLY MORNING HOURS.

&&

.FIRE WEATHER...
RELATIVE HUMIDITY VALUES WILL APPROACH CRITICAL LEVELS ON FRIDAY
AFTERNOON ACROSS NORTHERN FLORIDA...HOWEVER LONG DURATIONS ARE NOT
EXPECTED AT THIS TIME. INCREASED MOISTURE AND RAIN CHANCES THROUGH
THE WEEKEND WILL THEN KEEP FIRE WEATHER CONCERN LOW INTO EARLY NEXT
WEEK.
