AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 359 AM EDT SUN SEP 13 2015 .SHORT TERM (TODAY-MONDAY)... A STRONG U/L RIDGE IS CURRENTLY OVER THE WESTERN U.S. WITH A L/W TROUGH EXTENDING FROM THE GREAT LAKES TO THE NORTH CENTRAL GULF COAST. SIGNIFICANT U/L PATTERN CHANGE WILL BEGIN TO TAKE PLACE AS THE L/W TROUGH OVER THE EASTERN U.S. LIFTS OUT TO THE NORTHEAST TODAY AND TONIGHT...AND A DEEP TROUGH BEGINS TO DEVELOP ALONG THE WEST COAST OF THE U.S. EARLY NEXT WEEK THIS WILL ALSO INDUCE DOWNSTREAM RIDGING WITH BUILDING HEIGHTS OVER THE EASTERN THIRD OF THE COUNTRY. AT THE SURFACE...A FRONTAL BOUNDARY OVER NORTH CENTRAL FLORIDA WILL SINK SOUTH TODAY AND STALL ACROSS THE CENTRAL FLORIDA PENINSULA. ALTHOUGH MAIN U/L SUPPORT AND FORCING AS EXITED THE REGION...DEEP TROPICAL MOISTURE PERSISTS SOUTH OF THE FRONTAL BOUNDARY AND NUMEROUS SHOWERS AND SCATTERED THUNDERSTORMS WILL DEVELOP EARLY THIS MORNING OVER THE EASTERN GULF OF MEXICO AS COASTAL CONVERGENCE INCREASES AROUND SUNRISE...WITH SHOWER ACTIVITY PUSHING ONSHORE WEST CENTRAL FLORIDA DURING THE EARLY/MID MORNING HOURS. THE AREA OF SHOWERS AND THUNDERSTORMS WILL SINK SLOWLY SOUTH THROUGH THE DAY AS THE FRONTAL BOUNDARY SINKS SOUTH. DRIER AIR ALOFT IN THE WAKE OF THE FRONT WILL ADVECT OVER THE NORTHERN FORECAST AREA THROUGH THE DAY WITH A DECREASING CHANCE OF SHOWERS AND THUNDERSTORMS OVER THE NATURE COAST. SLIGHTLY COOLER DRIER AIR WILL ADVECT OVER THE NORTHERN FORECAST AREA TONIGHT IN THE WAKE OF THE COLD FRONT WITH OVERNIGHT LOWS DROPPING INTO THE LOWER 60S ACROSS INLAND LEVY COUNTY. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WILL REDEVELOP OVER THE COASTAL WATERS OF WEST CENTRAL FLORIDA AFTER MIDNIGHT TONIGHT AND MAY ADVECT LOCALLY ONSHORE DURING THE LATE NIGHT/EARLY MORNING HOURS...MAINLY FROM PINELLAS COUNTY AND SOUTH. THE FRONTAL BOUNDARY ACROSS THE CENTRAL FLORIDA PENINSULA WILL DISSIPATE TONIGHT AND MONDAY. SURFACE HIGH PRESSURE WILL BUILD OVER THE MID ATLANTIC COAST WITH BOUNDARY LAYER WINDS VEERING TO THE EAST TO NORTHEAST. DAYTIME HEATING ON MONDAY WILL LEAD TO INCREASING CONVECTIVE INSTABILITY. DEEP TROPICAL MOISTURE WILL REMAIN OVER THE CENTRAL AND SOUTHERN FORECAST AREAS...AND WILL GRADUALLY ADVECT NORTH OVER THE NATURE COAST. EASTERLY FLOW WILL HOLD THE WEST COAST SEA BREEZE BOUNDARY OVER THE COASTAL COUNTIES. INCREASED L/L CONVERGENCE ALONG THE SEA BREEZE BOUNDARY WILL BE THE FOCUS FOR NUMEROUS SHOWERS AND THUNDERSTORMS DURING THE MID TO LATE AFTERNOON HOURS. WITH DRIER MID LEVEL AIR OVER PORTIONS OF THE FORECAST AREA...A FEW STRONG STORMS POSSIBLE MONDAY AFTERNOON WITH MAIN THREAT DAMAGING WIND GUSTS. .LONG TERM (TUESDAY - NEXT SATURDAY)... AN ACTIVE WEATHER PATTERN LOOKS TO CONTINUE HEADING INTO NEXT WEEK. SURFACE HIGH PRESSURE WILL BECOME DOMINANT FROM THE MID ATLANTIC TO THE SOUTHEASTERN U.S. COASTLINE. TO THE SOUTH OF THIS FEATURE...EASTERLY GRADIENT FLOW LOOKS TO PERSIST FOR MUCH OF NEXT WEEK. WHILE HIGH PRESSURE WILL ATTEMPT TO BUILD BACK INTO THE AREA FROM THE WESTERN ATLANTIC...A WEAKNESS IN THE RIDGE ALOFT WILL DEVELOP...PROVIDING LITTLE IN THE WAY OF A HINDRANCE TO DAILY SHOWER AND THUNDERSTORM DEVELOPMENT. FROM WEDNESDAY THROUGH FRIDAY...A REMNANT TROPICAL LOW WILL MOVE FROM THE CARIBBEAN SEA NORTHWARD INTO THE CENTRAL AND EASTERN GULF OF MEXICO. THIS WILL BRING A SURGE OF DEEP MOISTURE INTO THE REGION...AND WITH LITTLE TO NO MID LEVEL STEERING FLOW...EXPECT THIS AREA OF LOW PRESSURE TO DRIFT SLOWLY NORTH AND WEST OVER THE GULF. AS A RESULT OF THIS FEATURE...SHOWER AND THUNDERSTORM COVERAGE WILL LIKELY BE ENHANCED...ESPECIALLY OVER THE WATERS NEARER THE AREA OF LOW PRESSURE. AS FOR STORM CHANCES INLAND...WITH PERSISTENT EASTERLY WINDS...THE EAST COAST SEABREEZE SHOULD MOVE QUICKLY INLAND...GENERATING AFTERNOON SHOWERS AND THUNDERSTORMS FROM EAST TO WEST ACROSS THE AREA. AREAS ALONG AND WEST OF I-75 WOULD HAVE GREATER CHANCES OF STORMS DURING THE LATE AFTERNOON TO EARLY EVENING HOURS EACH DAY...WHILE INLAND COUNTIES WOULD LIKELY EXPERIENCE SHOWERS AND STORMS FROM EARLY TO MID AFTERNOON. WITH THE ENHANCEMENT OF DEEP LAYER MOISTURE...EXPECT ANY THUNDERSTORMS THAT DEVELOP NEXT WEEK WILL CONTAIN HEAVY...POTENTIALLY FLOODING...RAINFALL. ESPECIALLY IN THE WEDNESDAY TO FRIDAY TIMEFRAME. THE THREAT OF HEAVY RAINFALL MAY PROLONG EXISTING FLOODING ON AREA RIVERS...AND PROMOTE ADDITIONAL FLOODING IN AREAS WHERE THE GROUND REMAINS SATURATED. AS WE MOVE TOWARD NEXT WEEKEND...LONG RANGE MODELS DEPICT PERHAPS A MORE SEASONABLE WEATHER PATTERN...AS UPPER LEVEL HIGH PRESSURE ATTEMPTS TO BUILD IN OVER THE REGION. HOWEVER...EASTERLY SURFACE WINDS LOOK TO CONTINUE WITH THE SURFACE RIDGE AXIS WELL TO THE NORTH OF THE AREA. && .AVIATION... DAYTIME HEATING WILL GENERATE LCL MVFR CIGS THIS MORNING 015-025...WITH PRIMARILY VFR CIGS THIS AFTERNOON. SCATTERED SHOWERS AND THUNDERSTORMS THIS MORNING AND EARLY THIS AFTERNOON WILL MAINLY IMPACT PIE/TPA/SRQ WITH LCL MVFR CIGS/IFR VSBYS. INCREASING CHANCE OF SHOWER AND THUNDERSTORMS THIS AFTERNOON OVER SOUTHWEST FLORIDA WITH LCL MVFR CIGS/IFR VSBYS POSSIBLY IMPACTING PGD/RSW/FMY. && .MARINE... MAIN HAZARD OVER THE WATERS THROUGH MONDAY WILL BE SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS WITH LOCALLY GUSTY WINDS AND ROUGH SEAS. HIGH PRESSURE WILL BUILD OVER THE MID ATLANTIC COAST MID WEEK WITH TIGHTENING GRADIENT OVER THE WATERS WHICH WILL INCREASE WINDS TO NEAR EXERCISE CAUTION LEVELS...WITH POTENTIAL FOR EASTERLY SURGE OF WIND DURING THE EVENING HOURS. && .FIRE WEATHER...
