AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
345 AM EDT WED AUG 15 2012

.SHORT TERM (TODAY-FRIDAY)...
MID/UPPER LEVEL RIDGING WILL HOLD ACROSS THE GULF AND FLORIDA INTO
THURSDAY THEN THE TROUGH OVER THE EASTERN U.S. WILL BEGIN TO
DEEPEN AS A SERIES OF SHORTWAVES MOVE THROUGH THE TROUGH.
MEANWHILE THE LOW LEVEL RIDGE AXIS WILL GENERALLY HOLD ACROSS
SOUTH CENTRAL FLORIDA WITH RATHER LIGHT FLOW SHIFTING TO SOUTHWEST
TO WEST EACH AFTERNOON AS THE WEST COAST SEA BREEZE DEVELOPS AND
MOVES WELL INLAND. SOME POCKETS OF DEEPER MOISTURE WILL MOVE
ACROSS NORTH FLORIDA ASSOCIATED WITH THE SHORTWAVES MOVING THROUGH
THE TROUGH...BUT THE EXACT TIMING OF THESE WAVES VARIES WITH EACH
MODEL RUN. EITHER WAY IT STILL LOOKS LIKE THERE WILL BE SUFFICIENT
MOISTURE ACROSS THE AREA TO CAUSE ISOLATED TO SCATTERED SHOWERS
AND THUNDERSTORMS OVER THE COASTAL WATERS LATE EACH NIGHT WHICH
WILL MOVE ONSHORE DURING THE MORNING HOURS AND THEN SHIFT INLAND
DURING THE AFTERNOON AND EVENINGS. MAIN THREATS WITH ANY STORMS
WILL CONTINUE TO BE FREQUENT LIGHTNING...GUSTY WINDS AND LOCALLY
HEAVY RAINFALL. DAYTIME HIGH TEMPERATURES WILL REMAIN NEAR TO A
COUPLE OF DEGREES ABOVE NORMAL IN THE UPPER 80S TO MID 90S WITH
OVERNIGHT LOWS ABOUT NORMAL AND MOSTLY IN THE 70S.

HIGH PRESSURE WILL RIDGE ACROSS THE AREA AT THE SURFACE AND ALOFT
THROUGH THE PERIOD WITH A WEAKENING BOUNDARY STALLING JUST NORTH
OF THE AREA SUNDAY NIGHT AND DISSIPATING THROUGH TUESDAY. GENERAL
AFTERNOON SCATTERED SEA BREEZE INDUCED THUNDERSTORMS WILL BE
POSSIBLE EACH DAY WITH RAIN CHANCES MAINLY 40 PERCENT...WITH SOME
ADDITIONAL MOISTURE ACROSS THE NORTH FROM THE BOUNDARY ALLOWING
SHOWERS TO LINGER DURING THE OVERNIGHT HOURS. TEMPERATURES WILL BE
IN THE 70S FOR LOWS AND IN THE UPPER 80S TO LOWER 90S FOR HIGHS.

&&

.AVIATION...
VFR CONDITIONS ARE IN PLACE WITH LIGHT WINDS. LATE MORNING SHOWERS
NEAR THE COAST MAY BE POSSIBLE AT KSRQ AND KPIE WITH THUNDERSTORMS

VFR WILL PREVAIL. WINDS WILL AGAIN BECOME LIGHT AFTER 00Z WITH VFR
CONDITIONS.

WEEKEND WITH WINDS AROUND 10 KNOTS OR LESS AND SEAS 2 FEET OR

SHOWERS AND THUNDERSTORMS.
