Hail and Damaging Winds in Florida, May 28, 2010

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
925 AM EDT FRI MAY 28 2010

.UPDATE...
THE UPPER AIR ANALYSIS THIS MORNING SHOWS A TROUGH OVER THE WESTERN
U.S...A RIDGE OVER THE PLAINS...AND TROUGHING OVER THE EAST. WATER
VAPOR IMAGERY SHOWS A SHORTWAVE OVER EASTERN ILLINOIS DIVING
SOUTHWARD TOWARDS THE SOUTHEAST U.S. THIS SHORTWAVE WILL LIKELY
ENHANCE OUR SHOWER AND THUNDERSTORM CHANCES THIS WEEKEND.

FOR THE REST OF TODAY...A WEAK PRESSURE PATTERN IS IN PLACE ACROSS
OUR LOCAL AREA. THIS WILL ALLOW MESOSCALE INFLUENCES TO DOMINATE OUR
WX TODAY (I.E. THE SEABREEZE). OFFSHORE FLOW TODAY IS WEAKER THAN
PREVIOUS DAYS...SO THE SEABREEZE SHOULD BE ALLOWED TO PROPAGATE
FURTHER INLAND THIS AFTERNOON WITH A SLIGHTLY LARGER AREA AFFECTED
BY AFTERNOON SHOWERS AND THUNDERSTORMS. THE 12 UTC TAE SOUNDING
SHOWS AN INCREASE IN MOISTURE COMPARED TO PREVIOUS SOUNDINGS...WITH
A PWAT OF 1.50 INCHES OBSERVED TODAY VS 1.31 INCHES LAST NIGHT.
MODIFYING THE 12 UTC TAE SOUNDING FOR AN AFTERNOON SURFACE T/TD OF
92/63 YIELDS AROUND 1800 J/KG OF SBCAPE. THE CURRENT 30 TO 40 POPS
ACROSS THE AREA STILL LOOK GOOD FOR THIS AFTERNOON. THE FCST OF
WIDESPREAD LOWER 90S THIS AFTERNOON ALSO STILL LOOKS GOOD AND TEMPS
MAY EVEN APPROACH THE MID 90S OVER SOUTHEAST AL AND SOUTHWEST GA IN
A FEW SPOTS. OVERALL...FEW IF ANY CHANGES TO TODAY'S FCST ARE
ANTICIPATED.

&&

.AVIATION...
THE TAF PERIOD WILL START WITH VFR CONDITIONS ACROSS THE REGION
WITH LIGHT WINDS AND SCATTERED MID LEVEL CLOUDS. AS THE SEA BREEZE
MAKES ITS WAY INLAND...SCATTERED TSRA WILL BE POSSIBLE THIS
AFTERNOON. HEAVY RAINFALL MAY BRIEFLY LOWER VSBYS TO MVFR LEVELS.
OTHERWISE...VFR CONDITIONS CAN BE EXPECTED INTO THE EVENING WITH
SOME PATCHY FOG DEVELOPING BY SATURDAY MORNING AT MOST TERMINALS.

&&

.MARINE...
LOCAL BUOYS THIS MORNING ARE SHOWING WESTERLY WINDS AROUND 10 KNOTS
WITH WAVE HEIGHTS AROUND 2 FT OFFSHORE. WINDS WILL DIMINISH SLIGHTLY
THIS AFTERNOON WITH GENERALLY 5 TO 10 KNOTS EXPECTED AND SEAS 1 TO 2
FT.

.TAE WATCHES/WARNINGS/ADVISORIES...

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 SHOWERS AND THUNDERSTORMS WILL DEVELOP TODAY...ESPECIALLY
IN THE AFTERNOON AND EVENING HOURS. WEAK UPPER LEVEL WINDS AND
UNSPECTACULAR INSTABILITY WILL LIMIT THE THREAT FOR WIDESPREAD
SEVERE STORMS...BUT A BRIEF STRONG TO SEVERE STORM CAN NOT BE
RULED OUT. THE CHANCE FOR SEVERE STORMS WITHIN 25 MILES OF ANY POINT
IS LESS THAN 5 PERCENT.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY...
SHOWERS AND THUNDERSTORMS ARE LIKELY THIS WEEKEND...ESPECIALLY IN
THE AFTERNOON AND EVENING HOURS. ONCE AGAIN...LIGHT WINDS ALOFT
WILL LIMIT THE THREAT FOR ORGANIZED SEVERE STORMS...BUT A FEW BRIEF
STRONG TO SEVERE STORMS ARE NEARLY IMPOSSIBLE TO RULE OUT THIS
TIME OF YEAR. SCATTERED MAINLY AFTERNOON AND EVENING STORMS WILL
CONTINUE INTO THE WORK WEEK.

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