Area forecast discussion, Jul 10, 1:54 PM EDT, 2 hours 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
154 PM EDT TUE JUL 10 2012

.SHORT TERM (TONIGHT - THURSDAY)...
A BROAD SURFACE RIDGE WILL CONTINUE TO DOMINATE THE FLORIDA WEATHER
PATTERN FOR THE NEXT FEW DAYS. THE RIDGE WILL SLOWLY SLIDE NORTH
THROUGH THE END OF THE WEEK WITH THE RIDGE AXIS STRETCHING ACROSS
NORTHERN FLORIDA AND SOUTHERN GEORGIA BY THURSDAY.

MOISTURE WILL INCREASE THROUGH THE SHORT TERM PERIOD...WITH MODEL
PRECIPITABLE WATER INCREASING TO OVER TWO INCHES WEDNESDAY AND
THURSDAY. THE INCREASED MOISTURE...COMBINED WITH A POCKET OF
ENHANCED MID LEVEL VORTICITY MOVING UP THE WEST COAST OF THE FLORIDA
PENINSULA TONIGHT AND WEDNESDAY...WILL ALLOW FOR INCREASED RAIN
CHANCES THROUGH THE SHORT TERM PERIOD. EXPECT POPS TO BE 50 TO 60
PERCENT OVER LAND IN THE AFTERNOONS EACH DAY. OVERNIGHT...POPS WILL
BE AROUND 30 PERCENT OR LESS...WITH BETTER RAIN CHANCES OFFSHORE.

TEMPERATURES WILL BE AROUND NORMAL TO A DEGREE OR A TWO ABOVE
NORMAL THROUGH THURSDAY.

.LONG TERM (THURSDAY NIGHT-TUESDAY)... STRONG U/L RIDGE WILL PERSIST
OVER THE FOUR CORNERS AREA FRIDAY...WITH ANOTHER STRONG RIDGE OVER
THE WESTERN ATLANTIC BUILDING BACK OVER THE SOUTHEAST U.S. AND
FLORIDA. OVER THE WEEKEND...THE RIDGE OUT WEST WILL BE SUPPRESSED
EASTWARD AND WEAKEN...WHILE THE RIDGE OVER WESTERN ATLANTIC WILL
HOLD OVER THE SOUTHEAST U.S. AND FLORIDA. SURFACE RIDGE AXIS WILL
REMAIN NORTH OF THE FORECAST AREA THROUGH THE WEEKEND WITH
EASTERLY BOUNDARY LAYER FLOW ACROSS WEST CENTRAL AND SOUTHWEST
FLORIDA. COMBINATION OF EASTERLY FLOW AND RIDGING ALOFT WILL ALLOW
TEMPERATURES TO REMAIN NEAR TO SLIGHTLY ABOVE CLIMATIC NORMALS.
ATMOSPHERE WILL BE CONDITIONALLY UNSTABLE THROUGH THE WEEKEND WITH
SEA BREEZE CONVERGENCE AND OUTFLOW BOUNDARIES FROM OLD CONVECTION
THE MAIN FOCUS FOR THUNDERSTORMS EACH DAY. EASTERLY BOUNDARY LAYER
FLOW WILL HOLD THE WEST COAST SEA BREEZE NEAR THE COAST EACH
DAY...WITH THUNDERSTORMS INCREASING IN AREAL COVERAGE DURING THE
LATE AFTERNOON AS THE EAST COAST SEA BREEZE COLLIDES WITH THE WEST
COAST BOUNDARY OVER THE COASTAL COUNTIES OF WEST CENTRAL AND
SOUTHWEST FLORIDA. EASTERLY FLOW WILL PUSH THE CONVECTION WEST
OVER THE COASTAL WATERS DURING THE EVENING HOURS. A FEW PULSE
SEVERE THUNDERSTORMS ARE POSSIBLE EACH DAY...WITH THE MAIN THREAT
DAMAGING WINDS AND HAIL.

&&

.AVIATION...
SURGE OF SHOWERS AND STORMS MAY REACH TPA AND PIE AFTER 20Z SO ADDED
TEMPO FOR 20 TO 22Z THERE. OTHERWISE...CONFIDENCE TOO LOW TO USE
ANYTHING OTHER THAN VCTS FOR LAL...SRQ...PGD...FMY AND RSW.

&&

.MARINE...
THE RIDGE OF HIGH PRESSURE STRETCHING ACROSS THE FLORIDA PENINSULA
AND INTO THE GULF OF MEXICO WILL SLOWLY LIFT NORTH OVER THE WATERS.
THIS WILL PRODUCE EAST TO SOUTHEAST WINDS AROUND 10 KNOTS OR LESS
WITH AFTERNOON SEA BREEZES. SHOWERS AND THUNDERSTORMS WILL DEVELOP
EACH DAY AND CONTINUE OVERNIGHT...WITH BETTER COVERAGE FARTHER TO
THE SOUTH.

.FIRE WEATHER...
HIGH DEW POINTS AND LIGHT WINDS WILL NEGATE ANY FIRE WEATHER RISK.
