AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 310 PM EDT FRI MAY 30 2014 ...STRONG AND SLOW MOVING THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL EXPECTED AT INLAND LOCATIONS THROUGH EARLY EVENING... .CURRENTLY... AFTERNOON SURFACE ANALYSIS DEPICTS HIGH PRESSURE (1020 MILLIBARS) CENTERED OFF THE GEORGIA COAST. A STATIONARY FRONTAL BOUNDARY WAS LOCATED WELL NORTH OF OUR REGION OVER THE CAROLINAS. ALOFT...A LARGE AND NEARLY STATIONARY CYCLONIC GYRE WAS SPINNING OVER THE LOWER MISSISSIPPI RIVER VALLEY...CREATING LIGHT SOUTHERLY FLOW THROUGHOUT A DEEP LAYER OVER OUR REGION. LOBES OF VORTICITY EMANATING FROM THIS CYCLONIC GYRE ARE CREATING NUMEROUS THUNDERSTORMS OVER THE CENTRAL AND EASTERN GULF OF MEXICO...AND ACTIVITY ALONG THE ATLANTIC AND GULF COAST SEA BREEZES IS DEVELOPING AND MOVING VERY SLOWLY INLAND DUE TO VERY WEAK STEERING FLOW ALOFT...WITH ISOLATED T0 WIDELY SCATTERED ACTIVITY DEVELOPING AT INLAND LOCATIONS. .NEAR TERM (THIS AFTERNOON AND TONIGHT)... CONVECTION ALONG THE ATLANTIC AND GULF COAST SEA BREEZES WILL MOVE INLAND AND CONVERGE IN THE REGION BETWEEN INTERSTATE 75 AND US HIGHWAY 301. EXPECTING STRONGER CONVECTION TO BE PULSE IN NATURE...WITH BRIEF STRONG WIND GUSTS AND SMALL HAIL POSSIBLE INLAND. THE STORM PREDICTION CENTER HAS PLACED MOST OF OUR INLAND AREAS IN A 5 PERCENT RISK FOR STRONG WIND GUSTS AND HAIL THROUGH THE EVENING HOURS. THE BIGGER THREAT WILL BE LOCALLY HEAVY RAINFALL AND THE POTENTIAL FOR URBAN FLOODING AT INLAND LOCATIONS THROUGH THE EARLY EVENING HOURS. RESIDUAL RAINS ALONG THE I-75 CORRIDOR SHOULD DIMINISH BY MIDNIGHT...WITH PATCHY FOG POSSIBLE INLAND WHERE THE HEAVIER RAINS FALL. LOWS INLAND WILL FALL TO THE MID AND UPPER 60S...WITH MID 70S AT THE COAST. .SHORT TERM (SATURDAY THROUGH SUNDAY NIGHT)... A WEAK COLD FRONT WILL PASS FROM NORTH TO SOUTH THROUGH THE AREA SATURDAY EVENING INTO SUNDAY WITH SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED EACH AFTERNOON. COVERAGE WILL BE SLIGHTLY LESS THAN WAS SEEN THE PREVIOUS COUPLE OF DAYS WITH THE AMOUNT OF DEEP LAYER MOISTURE SLOWLY DECREASING ACROSS THE AREA. TEMPS WILL BE IN THE UPPER 80S FOR SATURDAY THEN DROPPING A FEW DEGREES INTO THE MID 80S ON SUNDAY IN THE WAKE OF THE FRONTAL BOUNDARY. LOCAL PRESSURE GRADIENT WILL TIGHTEN AS HIGH PRESSURE BUILDS DOWN THE ATLANTIC COAST ON SUNDAY INCREASING ONSHORE WINDS TO AROUND 15 MPH IN COASTAL AREAS AND 10 MPH INLAND. .LONG TERM... MONDAY AND MONDAY NIGHT...SFC HIGH PRESSURE WILL CENTER ITSELF TO THE NORTHEAST OF THE AREA WITH DRIER AIR ACCOMPANYING IT LEAVING THE START OF THE WEEK WARM IN THE MID/UPPER 80S DURING THE AFTERNOON WITH LITTLE CHANCE OF PRECIPITATION. WINDS WILL REMAIN ONSHORE AROUND 10 MPH. TEMPS MONDAY NIGHT WILL BE MILD IN THE MID/UPPER 60S FOR LOWS. TUESDAY THROUGH THURSDAY NIGHT...WEAK RIDGING WILL BE IN CONTROL OF THE LOCAL WEATHER FOR THE LONG TERM PERIOD AS UPPER TROUGH SWINGS ACROSS THE NORTHERN GREAT LAKES AND INTO EASTERN CANADA. FOR NE FL AND SE GA...MOSTLY DRY CONDITIONS AND WARM TEMPERATURES ARE IN STORE WITH JUST ISOLATED SHOWERS/THUNDERSTORMS POSSIBLE FOR WEDNESDAY AND THURSDAY AFTERNOONS AS RIDGE BEGINS TO WEAKEN. TEMPS WILL BE IN THE LOW 90S ACROSS MUCH OF THE AREA WITH UPPER 80S ALONG THE COAST EACH AFTERNOON ACCOMPANIED BY LIGHT WINDS AND UPPER 60S/LOW 70S EACH NIGHT. && .AVIATION... VFR CONDITIONS WILL PREVAIL AT SSI. TEMPO GROUPS FOR SUB-VFR CONDITIONS CONTINUE THROUGH AROUND 22Z AT THE DUVAL COUNTY TERMINALS...WITH THE EAST COAST SEA BREEZE PUSHING ACTIVITY INLAND AFTER 22Z. TEMPO IFR CONDITIONS ARE EXPECTED AT GNV BETWEEN 21Z-01Z...WITH BRIEFLY STRONG WIND GUSTS AND LIFR CONDITIONS POSSIBLE AS STRONG THUNDERSTORMS POTENTIALLY MOVE OVER THE TERMINAL. VFR CONDITIONS SHOULD PREVAIL REGION-WIDE AFTER 03Z...WITH MVFR VISIBILITIES DEVELOPING AT VQQ AND POSSIBLY GNV AFTER 06Z. && .MARINE... SOUTHERLY WINDS WILL SURGE TO 10-15 KNOTS EARLY THIS EVENING...AND WILL SUBSIDE DURING THE OVERNIGHT HOURS. SEAS WILL REMAIN GENERALLY IN THE 1-2 FOOT RANGE WITH A LONG PERIOD SWELL OF 7-9 SECONDS. EXPECT SIMILAR CONDITIONS ON SATURDAY...WITH THE AFTERNOON SEA BREEZE INCREASING WINDS TO NEAR 10 KNOTS IN THE NEAR SHORE WATERS. STRONG HIGH PRESSURE WILL BUILD DOWN THE U.S. EASTERN SEABOARD ON SUNDAY...RESULTING IN AN EASTERLY WIND SURGE THAT WILL LIKELY BRING A PERIOD OF SMALL CRAFT ADVISORY WIND SPEEDS TO ALL WATERS FROM SUNDAY AFTERNOON THROUGH EARLY MONDAY. ELEVATED ONSHORE WINDS AND SEAS WILL CONTINUE ON MONDAY. WINDS AND SEAS WILL THEN DECREASE BY TUESDAY AND WEDNESDAY AS HIGH PRESSURE SETTLES OVER OUR REGION.
