AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
137 PM EDT MON JUN 28 2010

.SHORT TERM (TONIGHT - WEDNESDAY)...AS MENTIONED IN THE EARLIER
DISCUSSION...OUR SOUNDING CAME IN DRIER AND A BIT MORE STABLE
THAN YESTERDAY. LOOKING AT SURROUNDING SITES...IT APPEARS THAT
THE AIRMASS BECOMES MORE UNSTABLE AS YOU HEAD NORTH. FOR THE REST
OF TODAY...EXPECT BEST COVERAGE AND STRONGEST STORMS SO OCCUR
NORTH OF TAMPA BAY BUT CAN NOT RULE OUT SOME STRONG WIND GUSTS
JUST ABOUT ANYWHERE IN THE STRONGER STORMS.

A MORE SOUTHERLY FLOW WILL PROBABLY PREVENT THE EAST COAST SEA
BREEZE FROM MAKING IT ALL THE WAY ACROSS THE STATE THIS
EVENING...SO SCATTERED STORMS COULD BE ONGOING UNTIL MIDNIGHT.
WILL BUMP POPS UP BY 10 PERCENT FOR THE NATURE COAST BUT LEAVE
ISOLATED 20 PERCENT ELSEWHERE.

SCATTERED THUNDERSTORMS WILL DEVELOP AGAIN BOTH TUESDAY AND
WEDNESDAY AFTERNOONS ALONG SEA BREEZE BOUNDARIES. MID-LEVEL
TEMPERATURES ARE FORECAST TO REMAIN ON THE WARM SIDE AS THE RIDGE
HOLDS ON DESPITE A TROUGH RIDING BY TO THE NORTH. THE GFS HAS A
SURFACE TROUGH EXTENDING EASTWARD ALONG THE GULF COAST FROM
TROPICAL CYCLONE ALEX WHILE THE ECMWF AND NAM KEEP RIDGING IN
THROUGH WEDNESDAY. THE GFS HAS BEEN STRUGGLING WITH THE SYNOPTIC
PATTERN OVER THE GULF SINCE ALEX DEVELOPED...SO WILL CONTINUE TO
RELY ON OTHER MODELS FOR THIS PERIOD.

THAT SAID...IT IS STILL SUMMER...AND PRECIPITABLE WATERS WILL BE
IN THE 1.8 TO 2.0 RANGE BOTH TUESDAY AND WEDNESDAY. THIS WILL
SUPPORT HIGH END SCATTERED POPS EACH AFTERNOON...AND WE WILL
PROBABLY SEE HIGHER COVERAGE WHERE THE BEST MOISTURE CONVERGENCE
SETS UP. WE WILL KEEP POPS AT 50 PERCENT FOR EACH AFTERNOON...
WHICH IS A ABOVE MET GUIDANCE...BUT BELOW THE WETTER MAV.

.LONG TERM (WEDNESDAY NIGHT - MONDAY)...THE GFS IS IN SOMEWHAT
BETTER AGREEMENT WITH THE ECMWF TODAY BUT STILL A LOT OF
DIFFERENCES EXISTS BETWEEN THE TWO MODELS WITH REGARDS TO MOISTURE
AND RAINFALL POTENTIAL FOR THE FORECAST AREA...THUS LOW CONFIDENCE
IN THE FORECAST REMAINS THROUGH THE LONG TERM PERIOD. AT THE START
OF THE LONG TERM T.C. ALEX IS FORECAST BY TPC TO BE APPROACHING
THE MEXICO/TEXAS COASTS AS THE TAIL END OF THE EASTERN U.S. MID
LEVEL TROUGH AND ATTENDANT COLD FRONT SAGS SOUTH INTO THE
SOUTHEASTERN STATES.

SIMILAR TO YESTERDAY MODELS SHOW DEEP LAYERED MOISTURE STREAMING
INTO THE FORECAST AREA FROM THE GULF. THIS MOISTURE COMBINED WITH
THE AFOREMENTIONED TROUGH/FRONT SAGGING INTO THE PENINSULA AND THE
SEA BREEZE CIRCULATIONS SHOULD SUPPORT ABOVE NORMAL POPS WITH
SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED DAILY DURING THE
AFTERNOON AND EARLY EVENING HOURS. GIVEN THE DIFFERENCES IN THE
MODELS WILL KEEP INHERITED 50 PERCENT POPS IN PLACE FOR NOW
THROUGH SATURDAY...AND WILL WAIT TO SEE IF BETTER CONTINUITY
DEVELOPS AMONG THE MODELS OVER THE NEXT FEW DAYS.

DURING THE WEEKEND AND INTO EARLY NEXT WEEK MODEL DIFFERENCES
CONTINUE. UNLIKE YESTERDAY THE 00Z ECMWF IS NOW SHOWING MUCH
DRIER AIR MOVING INTO THE REGION FROM THE NORTH DURING THIS TIME
FRAME AS STRONG HIGH PRESSURE BUILDS IN OVER THE EASTERN
U.S...WHILE THE GFS NOW KEEPS ABUNDANT MOISTURE AND TROUGHING OVER
THE REGION. GIVEN THESE DIFFERENCES WILL KEEP POPS NEAR CLIMO (40
PERCENT) FOR NOW WITH A CONTINUATION OF SCATTERED AFTERNOON AND
EARLY EVENING SHOWERS AND THUNDERSTORMS. INCREASED CLOUD COVER AND
RAIN CHANCES SHOULD KEEP TEMPERATURES NEAR CLIMO WITH DAYTIME
HIGHS IN THE UPPER 80S TO LOWER 90S...WITH OVERNIGHT LOWS IN THE
70S.

&&

.AVIATION...
BRIEF MVFR/IFR CEILINGS AND VISIBILITIES MAY AFFECT
THE TERMINAL SITES THIS AFTERNOON AFTER 28/18Z AND LASTING INTO
THE EARLY EVENING HOURS AS THUNDERSTORMS DEVELOP OVER THE
REGION...AND HAVE INCLUDED TEMPO GROUPS IN THE TAFS TO ACCOUNT FOR
THIS. OUTSIDE OF THE THE CONVECTION VFR CONDITIONS ARE EXPECTED
DURING THE NEXT 24 HOURS. EAST SOUTHEAST WINDS IN THE 5 TO 10 KNOT
RANGE WILL BECOME WEST TO NORTHWEST AROUND 10 KNOTS AFTER 28/20Z
FROM SARASOTA NORTH TO TAMPA AS THE WEST COAST SEA BREEZE
DEVELOPS...WITH WIND GUSTS UP TO 30 KNOTS POSSIBLE IN THE VICINITY
OF THUNDERSTORMS.

&&

.MARINE...THE SURFACE RIDGE AXIS SHOULD REMAIN ACROSS THE
PENINSULA THROUGH FRIDAY BEFORE SLIPPING TO THE SOUTH ON SATURDAY.
NO SIGNIFICANT HAZARDS ARE ANTICIPATED AT THIS TIME...BUT SOME
MODELS SUGGEST WE COULD SEE AN INCREASE IN THUNDERSTORM ACTIVITY
AS MOISTURE FROM ALEX BECOMES INVOLVED WITH A SURFACE TROUGH TO
THE NORTH. WINDS SHOULD BE 15 KNOTS OR LESS AND SEAS 4 FEET OR
LESS THROUGH THE PERIOD.

&&

.FIRE WEATHER...NO FIRE WEATHER PROBLEMS EXPECTED WITH WARM AND
HUMID AIRMASS IN PLACE.
