AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
237 PM EDT THU JUN 18 2015

.SHORT TERM (TONIGHT-FRIDAY)...
SCATTERED THUNDERSTORMS THIS AFTERNOON WILL GRADUALLY DISSIPATE
BY MIDNIGHT WITH SKIES BECOMING MOSTLY CLEAR LATE TONIGHT/EARLY
FRIDAY MORNING. A FEW THUNDERSTORMS MAY REDEVELOP OVER THE COASTAL
WATERS LATE TONIGHT.

THE STRONG U/L RIDGE OVER THE SOUTHEAST U.S. WILL WEAKEN A BIT
FRIDAY AND SLIDE OFF THE SOUTHEAST COAST.  STRONG SUBSIDENCE WILL
PERSIST OVER WEST CENTRAL AND SOUTHWEST FLORIDA WITH CONTINUED ABOVE
NORMAL TEMPERATURES.  BOUNDARY LAYER WINDS WILL BE WEAKLY
ONSHORE...WHICH SHOULD KEEP MAX TEMPS NEAR THE COAST IN THE UPPER
80S TO LOWER 90S.  HOWEVER INLAND AREAS WILL AGAIN TOP OUT GENERALLY
BETWEEN 94 TO 97 WHICH WILL CREATE HEAT INDICES FRIDAY AFTERNOON OF
102 TO 107...WHICH IS JUST BELOW CRITERIA FOR A HEAT ADVISORY.

THE WEAK ONSHORE FLOW MAY ALLOW THE WEST COAST SEA BREEZE TO PUSH A
BIT FURTHER INLAND THAN THE PAST SEVERAL DAYS...BECOMING ORIENTED
MORE NORTH/SOUTH DOWN THE SPINE OF THE PENINSULA LATE FRIDAY
AFTERNOON.  SCATTERED THUNDERSTORMS WILL DEVELOP ACROSS THE FORECAST
AREA FRIDAY AFTERNOON WITH GREATEST AREAL COVERAGE NEAR AND ALONG
THE SEA BREEZE BOUNDARY. COMBINATION OF STRONG INSOLATION...SLIGHT
DRY POCKET ALOFT...AND BOUNDARY COLLISIONS WILL CREATE CONDITIONS
FAVORABLE FOR AN ISOLATED PULSE STRONG/SEVERE THUNDERSTORM FRIDAY
AFTERNOON.

.LONG TERM (FRIDAY NIGHT - THURSDAY)...
A STRONG MID/UPPER LEVEL HIGH PRESSURE CENTER NORTH OF THE
BAHAMAS CONTINUES TO RIDGE WESTWARD OVER THE FLORIDA PENINSULA.
UPPER LEVEL TROUGHING ASSOCIATED WITH THE REMNANTS OF TROPICAL
DEPRESSION BILL MOVES ACROSS TENNESSEE ON SUNDAY AND WILL CAUSE
THE RIDGE TO SLIGHTLY SHIFT SOUTHWARD...BUT THE RIDGE WILL STILL
MAINTAIN CONTROL OVER THE REGION. BY THE BEGINNING OF NEXT
WEEK...ANOTHER HIGH PRESSURE CENTER THAT WAS CENTERED OVER THE
WEST COAST WILL MOVE EASTWARD SETTING UP OVER THE SOUTHEAST CONUS.
ON THE SURFACE...A 1020 MB HIGH PRESSURE CENTER NORTH OF THE
BAHAMAS RIDGES WEST ACROSS THE CENTRAL FLORIDA PENINSULA INTO THE
GULF OF MEXICO. A SECONDARY HIGH PRESSURE CENTER IS ALSO PRESENT
IN THE GULF OF MEXICO. THIS WILL ALLOW FOR A MORE NORTHWEST
ONSHORE WIND FLOW OVER THE COASTAL WATERS...ESPECIALLY OVER THE
NATURE COAST AND LIGHT AND VARIABLE FLOW OVER THE INTERIOR. THIS
ONSHORE FLOW COMBINED WITH THE DAILY WEST COAST SEA BREEZE AND
CONVERGENCE WITH THE EAST COAST SEA BREEZE...WILL ALLOW FOR
SCATTERED SHOWERS AND STORMS EACH DAY INTO THE WEEKEND OVER THE
CENTRAL PORTION OF THE STATE...THEN MOVING BACK WESTWARD OVER THE
COASTAL WATERS OVERNIGHT. THIS PATTERN WILL REMAIN UNCHANGED
THROUGH NEXT WEEK WITH CONTINUED AFTERNOON/EVENING STORMS AND
ABOVE NORMAL TEMPERATURES ACROSS THE REGION.

&&

.AVIATION...
PREDOMINATELY VFR CONDITIONS THE NEXT 24 HOURS. SCATTERED
THUNDERSTORMS THIS AFTERNOON AND EVENING WILL CREATE LCL MVFR CIGS
AND IFR VSBYS...WITH THE BEST CHANCE OF THUNDERSTORMS IMPACTING
RSW/FMY/TPA/LAL.

&&

.MARINE...
HIGH PRESSURE WILL HOLD OVER THE WATERS WITH WINDS LESS THAN 15
KNOTS AND SEAS LESS THAN 4 FEET THROUGH THE PERIOD. MAIN HAZARD
WILL BE ISOLATED TO SCATTERED MAINLY OVERNIGHT/EARLY MORNING
THUNDERSTORMS WHICH MAY PRODUCE LOCALLY STRONG GUSTY WINDS AND
ROUGH SEAS.

&&

.FIRE WEATHER...
NO FIRE WEATHER HAZARDS THROUGH THE PERIOD. RELATIVE HUMIDITY
VALUES WILL REMAIN ABOVE CRITICAL LEVELS EACH DAY.
