WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY - RUSKIN FL
245 AM EDT THU MAY 24 2007
.SHORT TERM (TONIGHT - SATURDAY)...SURFACE HIGH PRESSURE WILL HOLD
OVER THE REGION THROUGH SATURDAY WITH EASTERLY FLOW PERSISTING. DRY
AIR WILL REMAIN ENTRENCHED OVER THE AREA THROUGH THE PERIOD. TIGHT
GRADIENT OVER THE PENINSULA WILL CAUSE GUSTY EAST TO NORTHEAST
WINDS...AND WILL BE STRONG ENOUGH FROM BROOKSVILLE SOUTH FOR THE
NEED OF A LAKE WIND ADVISORY. WINDS WILL DECREASE OVER WEST CENTRAL
FLORIDA TONIGHT...BUT THE GRADIENT WILL REMAIN TIGHT ON SATURDAY WITH
GUSTY EAST TO NORTHEAST WINDS ONCE AGAIN. GRADIENT WILL WEAKEN A
BIT ON SATURDAY...BUT WILL REMAIN RELATIVELY TIGHT. DRY CONDITIONS
WILL PERSIST WITH NO RAIN EXPECTED THROUGH SATURDAY. MAX
TEMPERATURES WILL CONTINUE TO RUN A FEW DEGREES ABOVE NORMAL...
WHILE THE DRY AIR OVER THE REGION WILL ALLOW OVERNIGHT MINS TO RUN
SEVERAL DEGREES BELOW NORMAL.
.LONG TERM (SATURDAY NIGHT - WEDNESDAY)...00Z GFS RUN AND ITS
ASSOCIATED MEX GUIDANCE IS A BIT WETTER THAN PREVIOUS RUNS FOR THE
FIRST HALF OF NEXT WEEK. THE OVERALL PATTERN LOOKS SIMILAR...WITH
STRONG HIGH PRESSURE REMAINING STATIONARY OVER THE MID-ATLANTIC
COAST MAINTAINING MODERATE EASTERLY FLOW OVER THE REGION. THE ONLY
DIFFERENCE IS THAT THIS LATEST RUN HAS MORE AMPLITUDE TO VARIOUS
INVERTED TROUGHS MOVING WESTWARD SOUTH OF THE STRONG RIDGE. WE HAVE
SEEN THIS FROM THE GFS IN THE PAST...WITH THE OVER-DEVELOPMENT OF
SURFACE LOW PRESSURE COMING AROUND THE SOUTH SIDE OF THE RIDGE.
SINCE THIS IS NOT A TREND...BUT RATHER A CHANGE FROM PREVIOUS
RUNS...I WILL LEAVE THE CURRENT FORECAST AS IT IS WITH JUST ISOLATED
RAIN CHANCES...AND MAINLY OVER THE SOUTHERN HALF OF THE FORECAST
AREA.
&&
.AVIATION...VFR CONDITIONS WILL CONTINUE OVER THE NEXT 24 HOURS.
GUSTY WINDS WILL PREVAIL ONCE AGAIN...ESPECIALLY AFTER SUNRISE
AROUND FMY/RSW.
&&
.MARINE...SCA CONDITIONS WILL CONTINUE TO TODAY FOR THE OFFSHORE
WATERS...AND WILL DEVELOP OVER THE NEAR SHORE WATERS THIS
AFTERNOON. EASTERLY SURGE WILL ALLOW SCA CONDITIONS UNTIL ABOUT
MIDNIGHT OVER THE NEAR SHORE WATERS...BUT WILL DECREASE TO SCEC
AFTER MIDNIGHT. SCA CONDITIONS WILL PERSIST OVER THE OFFSHORE
WATERS THROUGH THE NIGHT. WINDS AND SEAS WILL REMAIN HIGH FOR THE
NEXT SEVERAL DAYS...WITH SCA CONDITIONS OVER THE NEAR SHORE WATERS
LIKELY EACH AFTERNOON.

.FIRE WEATHER...DRY AIR OVER THE REGION TODAY WILL ALLOW AFTERNOON
RELATIVE HUMIDITY VALUES TO FALL BELOW 35 PERCENT OVER MUCH OF
WEST CENTRAL AND SOUTHWEST FLORIDA...WITH BREEZY CONDITIONS
EXPECTED AGAIN ACROSS THE REGION. EASTERLY LOW LEVEL WINDS WILL
ALLOW SLIGHTLY HIGHER DEW POINTS OVER THE INTERIOR...ALONG WITH
SLIGHTLY LOWER MAX TEMPS. THIS SHOULD KEEP MIN RH OVER THE INTERIOR
ABOVE CRITICAL LEVELS...HOWEVER CONDITIONS WILL BE DRY AND WITH
BREEZY CONDITIONS IF ANY WILDFIRES DUE OCCUR SPREAD WOULD BE
RATHER RAPID. RED FLAG CONDITIONS DUE TO LOW RH AND WIND LIKELY
OVER THE WESTERN PENINSULA. DRY CONDITIONS WILL PERSIST FRIDAY
AFTERNOON WITH RED FLAG CONDITIONS AGAIN POSSIBLE OVER MUCH OF WEST
CENTRAL AND SOUTHWEST FLORIDA.
