Severe Thunderstorm Warning 104, NWS Tallahassee, FL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
247 PM EDT TUE JUN 10 2008

.SYNOPSIS...
THE 17 UTC REGIONAL SURFACE ANALYSIS SHOWED A WEAK PRESSURE
PATTERN ACROSS THE SOUTHEAST U.S. WITH A HIGH PRESSURE RIDGE
ORIENTED EAST TO WEST ACROSS THE FL PENINSULA. LOCAL RADARS SHOWED
SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING ACROSS OUR FORECAST
AREA MAINLY ALONG THE SEA BREEZE FRONTS...ESPECIALLY ACROSS
SOUTHEAST PORTIONS OF THE FL BIG BEND. THE SURFACE AIRMASS HAS
BEEN DRIER THAN FORECAST (WITH DEWPOINTS DROPPING INTO THE LOWER
60S ACROSS SOUTHWEST GA)...SO THIS AREA HAS BEEN GENERALLY VOID OF
STORMS SO FAR. VAPOR IMAGERY AND UPPER AIR PROFILERS SHOWED AN
UPPER LEVEL LOW CENTERED OVER NORTH FL.

&&

.SHORT TERM...
(TONIGHT THROUGH FRIDAY) THE LARGE SCALE WEATHER PATTERN WILL BE
RATHER STAGNANT OVER OUR AREA AS WE REMAIN SOUTH OF A HIGH
PRESSURE RIDGE AT THE 500 MB LEVEL. THE STRONG SUBSIDENCE (AND
ACCOMPANYING MID LEVEL DRY AIR) WILL REMAIN WELL TO OUR NORTHEAST
(NEAR THE CENTER OF A 500 MB HIGH OFF THE MID ATLANTIC
COAST)...LEAVING OUR REGION WITH PLENTY OF DEEP LAYER MOISTURE.
SCATTERED THUNDERSTORMS WILL DEVELOP EACH DAY...MAINLY ALONG SEA
BREEZE FRONTS AND OUTFLOW BOUNDARY COLLISIONS. THERE IS SOME
DISAGREEMENT AMONG THE LATEST NUMERICAL GUIDANCE ABOUT THE
1000-700 MB MEAN WIND...WHICH COULD HAVE AN IMPACT ON HOW MUCH AND
WHEN AFTERNOON STORMS WILL DEVELOP. FOR NOW WE WILL USE A BLEND OF
THE GUIDANCE AND FORECAST A FLOW OF 5 TO 8 KT OUT OF THE
SOUTHEAST. OUR POP WILL BE IN THE 40-50 PERCENT RANGE...WHICH IS A
BIT ABOVE CLIMATOLOGY. TEMPERATURES WILL BE NEAR AVERAGE FOR THIS
TIME OF YEAR. A FEW PULSE SEVERE STORMS WILL REMAIN POSSIBLE EACH
AFTERNOON AS THE SBCAPE WILL BE NEAR 2500 J/KG EACH DAY.

.LONG TERM...
(SATURDAY THROUGH TUESDAY) FORECAST TRENDS CONTINUE TO INDICATE A
SIGNIFICANT CHANGE IN THE LARGE SCALE PATTERN ACROSS NORTH
AMERICA...RESULTING IN A GRADUAL RETROGRESSION OF THE STRONG HOT
RIDGE THAT HAS BEEN FIRMLY ENTRENCHED OVER THE EASTERN U.S. AND
ALLOWING A WEAKENING COLD FRONT TO PUSH INTO THE SOUTHEAST U.S. ON
SATURDAY AND SUNDAY. STILL SOME DISAGREEMENT AS TO THE AMPLITUDE
OF THE PATTERN...AND CONSIDERING THE TIME OF YEAR EXPECT THE FRONT
TO STALL OVER OR JUST TO THE NORTH OF OUR AREA AND SLOWLY
WEAKEN...AND IN CONJUNCTION WITH THE SEABREEZE...TO PROVIDE AN
ADDITIONAL FOCUS FOR CONVECTION INTO THE FIRST OF THE WEEK. EXPECT
TEMPERATURES WILL BE NORMAL LEVELS.

&&

.AVIATION...
AN ACTIVE SEA BREEZE AIDED BY MID/UPPER LEVEL LOW OVER NORTH
CENTRAL FL HAS INCREASED COVERAGE OF DEEP MOIST CONVECTION AS
FORECAST. HAVE TEMPO GROUPS FOR MVFR CIGS AND MVFR-LOCAL IFR VSBYS
IN TSRA THIS AFTERNOON THROUGH EARLY EVENING. ALSO, WIND GUSTS OF
30 KTS OR HIGHER WILL ALSO BE POSSIBLE INVOF STRONGER TSRA. THE
CONVECTION SHOULD BEGIN TO WIND DOWN BETWEEN 00Z AND 02Z THIS
EVENING, FOLLOWED BY SCATTERED MAINLY HIGH CLOUDS AND
LIGHT/VARIABLE WINDS. THE LATEST NAM12 SURFACE CONDENSATION
PRESSURE DEFICIT PROGS INDICATE THE BEST POTENTIAL FOR MVFR-LOCAL
IFR VSBYS WILL BE INVOF KVLD AROUND SUNRISE WEDNESDAY. OTHERWISE,
PARTLY CLOUDY SKIES AND LIGHT WINDS ARE FORECAST FOR WEDNESDAY
MORNING.

&&

.MARINE...
LOW WINDS AND SEAS WILL CONTINUE THROUGH THE WEEK WITH A SURFACE
RIDGE NEAR THE AREA.

&&

.FIRE WEATHER...
THE RELATIVE HUMIDITY MAY BRIEFLY DROP NEAR 35 PERCENT WEDNESDAY
AND THURSDAY AFTERNOONS...BUT NOT LONG OR WIDESPREAD ENOUGH FOR A
RED FLAG WARNING.
