Hail and Damaging Winds in Florida, June 26, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
358 PM EDT THU JUN 26 2014

.SYNOPSIS...
ALOFT - A SHORT WAVE TROUGH WAS ACROSS THE WEST GULF COAST AND LOWER
MISSISSIPPI VALLEY WHILE A RIDGE CENTERED OVER SOUTHEASTERN GULF OF
MEXICO SPRAWLED EAST OVER FL. A SECOND SHORT WAVE TROUGH WAS NORTH
AND NORTHEAST OF THE BAHAMAS. SURFACE - A FRONTAL TROUGH STRETCHED
ALONG THE EASTERN SEABOARD FROM THE SOUTHEAST U.S. TO NEW ENGLAND.
ATLANTIC HIGH PRESSURE RIDGED WEST...THROUGH THE NORTHERN BAHAMAS
AND SOUTHERN FL...TO THE NORTH-CENTRAL GULF COASTAL WATERS.

&&

.SHORT TERM (TONIGHT AND FRIDAY)...
THE SHORT WAVE TROUGHS LIFTS UP TO THE NORTHEAST...REACHING THE TN
VALLEY/SOUTHEAST U.S. FRI...AS THE GULF RIDGE SHIFT EASTWARD ACROSS
FL. THE ATLANTIC RIDGE CONTINUES TO STRETCH ACROSS SOUTHERN FL INTO
THE GULF...DOMINATING THE FORECAST AREA...AS A WEAK LOW FORMS ON THE
SOUTH END OF THE FRONTAL TROUGH/JUST OFF THE SOUTHEAST U.S. COAST/
BY LATE FRIDAY.

FOR THE REST OF THIS AFTERNOON...
RATHER QUIET AT MID AFTERNOON BUT STILL EXPECT SOME SHOWERS AND
STORMS THAT WIND SOWN IN THE EARLY EVENING.

TONIGHT AND FRIDAY...
THE UPPER LEVEL RIDGING SLIDES ACROSS...HELPING TO KEEP
TEMPERATURES SLIGHTLY ABOVE NORMAL...HOWEVER THERE WILL BE ENOUGH
MOISTURE... INSTABILITY...AND SEA BREEZE BOUNDARY CONVERGENCE TO
SUPPORT ISOLATED TO SCATTERED SHOWERS AND STORMS WITH THE HIGHEST
COVERAGE INLAND AND IN THE AFTERNOON.

.MID TERM (FRIDAY NIGHT-SATURDAY)...
ATLANTIC HIGH PRESSURE CONTINUES TO BE THE MAJOR SYNOPTIC FEATURE
AFFECTING FLORIDA TO KICK OFF THE WEEKEND. PLENTY OF AVAILABLE
MOISTURE WILL PROVIDE FOR HEALTHY RAIN AND THUNDERSTORM
CHANCES...ESPECIALLY ALONG SEA BREEZE AND OTHER BOUNDARY COLLISIONS.
WARM TEMPERATURES WILL CONTINUE WITH HIGHS REACHING INTO THE 90S
ACROSS THE AREA AND OVERNIGHT LOWS IN THE 70S WITH LOWER 80S ALONG
THE COAST. GFS MAV COOP MOS GUIDANCE OFFERED A BETTER SNAPSHOT OF
MAX TEMPERATURES THAN THE COOLER NAM MET MOS GUIDANCE.

.LONG TERM (SATURDAY NIGHT-NEXT THURSDAY)...
HIGH PRESSURE CONTINUES OVER THE AREA TO END THE WEEKEND. BOTH THE
00Z ECMWF AND 00Z GFS ARE MOVING AN AREA OF DISTURBED WEATHER ACROSS
FLORIDA FROM THE ATLANTIC ON MONDAY INTO TUESDAY. IT IS TOO EARLY TO
TELL THE EXACT IMPLICATIONS OTHER THAN AN INCREASED CHANCE OF RAIN
DEPENDING ON TRACK. THE INCREASED CLOUDS WITH THE ADDED TROPICAL
MOISTURE COULD ALSO HELP KEEP A LID ON TEMPERATURES...MODERATING
BOTH THE MAX AND MIN TEMPERATURES. FOR THE LATEST ON POTENTIAL
TROPICAL DEVELOPMENT...PLEASE REFERENCE THE LATEST ATLANTIC TROPICAL
WEATHER OUTLOOK /TWOAT/ FROM THE NATIONAL HURRICANE CENTER.

THE DISTURBANCE EXITS INTO THE GULF ON WEDNESDAY...INTERACTING WITH
A FRONTAL SYSTEM AND 500MB TROUGH. THE 00Z ECMWF IS MUCH MORE
AGGRESSIVE WITH DEFINING A LOW FROM THE SURFACE UP TO 500 MB...WHILE
THE 00Z GFS RESOLVES A DIFFUSE AREA OF MOISTURE ACROSS MUCH OF THE
EASTERN GULF AND FLORIDA. EITHER WAY...THE HIGHER RAIN TRENDS AND
MODERATED TEMPERATURES CONTINUE INTO THURSDAY. FORECAST CONFIDENCE
IS LOW...THOUGH GUIDANCE IS TRENDING CLOSER TO AGREEMENT WITH THE
00Z RUN.

&&

.AVIATION...
TIL 27/18Z...GENERALLY VFR ALTHOUGH EXPECT SOME LATE AFTERNOON TSRA
ESPECIALLY IN THE SOUTH TO RESULT IN TEMPO MVFR FMY AND RSW...JUST
VCNTY TSRA ELSEWHERE. WEST OR NW WINDS INTO THE EVENING THEN LIGHT
AND VARIABLE OVERNIGHT. WINDS PICK UP SLIGHTLY FRI MORNING FROM
THE NORTH OR NE.

&&

.MARINE...
ATLANTIC HIGH PRESSURE RIDGING IN ACROSS FL TO THE GULF...WITH A
RATHER RELAXED GRADIENT...WILL DOMINATE THE WATERS INTO NEXT WEEK.
A WEAK AREA OF LOW PRESSURE FORMS OFF THE SE U.S. COAST FRI AND
MEANDERS THERE THROUGH THE WEEKEND. MAIN MARINE CONCERN WILL BE
SCATTERED AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WITH
LOCALLY HIGHER WINDS AND SEAS.

&&

.FIRE WEATHER...
ISOLATED TO SCATTERED SHOWERS AND STORMS THE AFTERNOON AND EVENING
EACH DAY. RELATIVE HUMIDITY VALUES WILL REMAIN ABOVE CRITICAL
THRESHOLDS THROUGH THE PERIOD.
