AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 923 PM EDT SUN APR 14 2013 .SYNOPSIS... LOW PRESSURE SYSTEM WILL TRACK FROM THE NORTHERN GULF OF MEXICO TO THE SOUTHEAST COAST TONIGHT INTO EARLY MONDAY...THEN WILL PULL AWAY FROM THE REGION AND WEAKEN MONDAY AS HIGH PRESSURE CONTINUES TO RIDGE INTO THE FORECAST AREA. HIGH PRESSURE WILL GRADUALLY STRENGTHEN OVER THE WESTERN ATLANTIC TUESDAY THROUGH FRIDAY BEFORE A COLD FRONT MOVES IN FRIDAY NIGHT. HIGH PRESSURE WILL BUILD INTO THE REGION NEXT WEEKEND. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... MADE MINOR TIMING ADJUSTMENTS PER GOING RADAR TRENDS. WATCHING A SEVERE LINE SEGMENT MOVING NE OUT OF FAR SOUTHERN GA. THIS FEATURE IS LIKELY BEING SUPPORTED BY INTENSE FORCING ASSOCIATED WITH THE LEADING EDGE OF A MESOHIGH THAT FORMED IN THE WAKE OF AN EARLIER SQUALL LINE. SVR TSTM WRNG MAY BE NEED FOR LONG-MCINTOSH COUNTIES WITHIN THE HOUR. SPECIAL MARINE WRNGS MAY ALSO BE NEEDED. FARTHER WEST...HIGH WINDS ASSOC WITH A WAKE LOW ARE MOVING RAPIDLY E ACROSS CNTRL GA. THESE WNDS HAVE CAUSED DAMAGED IN A FEW LOCALES PER REPORTS FROM WFO ATLANTA. WINDS AT DUBIN AND EASTMAN SUGGEST SPEEDS MAY BE DIMINISHING AT BIT AS THE LOW FILLS. WILL HOLD WIND GUSTS AT 35 MPH FOR NOW...BUT A WIND ADV MAY BE NEEDED FOR 2-3 HOUR ACROSS THE WRN ZONES. UPDATED GRIDS/TXT PRODUCTS HAVE BEEN ISSUED. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... MONDAY AND MONDAY NIGHT...THE PERIOD WILL START OUT WITH THE POTENT 500 MB SHORTWAVE PUSHING OUT OVER THE WESTERN ATLANTIC AS THE SURFACE LOW PASSES BY RIGHT ALONG THE SC COASTLINE. ANY LINGERING SHOWER/THUNDERSTORM ACTIVITY SHOULD BE LIMITED TO THE NORTHEAST CORNER OF THE FORECAST AREA AND BE ON A DIMINISHING TREND AS MID LEVEL LAPSE RATES WEAKEN. THE REMAINDER OF THE DAY WILL SEE LOW STRATUS ACROSS MUCH OF THE AREA...ERODING FROM SOUTHWEST TO NORTHEAST THROUGH THE AFTERNOON. WE MAY SEE ADDITIONAL SHOWERS...BUT POPS HAVE BEEN LIMITED TO SLIGHT CHANCE FOR MUCH OF THE DAY AND EVENTUALLY THE FORECAST GOES DRY BY LATE AFTERNOON. THE STUBBORN CLOUDS WILL HAVE THE GREATEST AFFECT ON TEMPERATURES. AREAS ACROSS SOUTHEAST GA WILL LIKELY SCATTER OUT SOONEST AND SEE THE QUICKEST WARM UP INTO THE UPPER 70S TO NEAR 80. THE TRI-COUNTY WILL BE THE COOLEST WHERE THE CLOUDS HANG ON THE LONGEST AND WILL TOP OUT IN THE MID 70S. OVERNIGHT...THE PRIMARY FORECAST PROBLEM WILL BE THE POTENTIAL FOR LOW STRATUS AND FOG DEVELOPMENT. WITH CONSIDERABLE LOW LEVEL MOISTURE BEING TRAPPED BENEATH THE NOCTURNAL INVERSION AND DRYING IN THE MID/UPPER LEVELS...SHOULD BE GOOD FOG CONDITIONS. ONE SLIGHT LIMITING FACTOR MAY BE ENOUGH LINGERING LOW LEVEL FLOW. EXPECT A MILD NIGHT WITH LOWS FALLING THE LOW 60S/NEAR 60. TUESDAY THROUGH WEDNESDAY...UPPER RIDGING ALOFT WILL BUILD IN AS THE AREA STAYS UNDER THE INFLUENCE OF ATLANTIC HIGH PRESSURE AT THE SURFACE. WE WILL LIKELY CONTINUE TO SEE A GOOD AMOUNT OF CLOUD COVER TUESDAY WITH LINGERING LOW LEVEL MOISTURE. SOME MODELS CONTINUE TO DEVELOP ISOLATED AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS THE FAR WESTERN ZONES EACH DAY...BUT A PERUSAL OF MODEL SOUNDINGS SHOWS A CONSIDERABLE SUBSIDENCE INVERSION UNDER THE RIDGE ALOFT. HAVE KEPT THE FORECAST DRY TUESDAY BUT CONTINUED THE SMALL SLIVER OF SLIGHT CHANCES FAR TO THE WEST ON WEDNESDAY DUE TO BETTER SURFACE HEATING. TEMPS WILL RISE A COUPLE OF DEGREES EACH DAY...TOPPING OUT IN THE LOW 80S BY WEDNESDAY. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... THE UPPER RIDGE WILL HANG ON FOR ONE MORE DAY BEFORE A LARGE SCALE PATTERN SHIFT OCCURS. A PRONOUNCED LONGWAVE TROUGH WILL SPREAD ACROSS PRETTY MUCH THE ENTIRE CONTIGUOUS UNITED STATES FRIDAY THROUGH SUNDAY. A STRONG COLD FRONT WILL SWEEP THROUGH THE AREA FRIDAY NIGHT WITH DRY CANADIAN HIGH PRESSURE BUILDING IN ITS WAKE. WE EXPECT DECENT COVERAGE OF SHOWERS AND THUNDERSTORMS FRIDAY AFTERNOON THROUGH FRIDAY NIGHT...THEN DRIER AND MUCH COOLER WEATHER FOR THE WEEKEND. HIGHS ON SATURDAY COULD STRUGGLE TO REACH 70 DEGREES AND SATURDAY NIGHT WE COULD SEE SOME UPPER 40S IN SPOTS. && .AVIATION /01Z MONDAY THROUGH FRIDAY/... RA WL OVRSPRD THE TERMINALS THIS EVNG AS LOW PRES REDVLPS OFF THE SC/GA COAST. THE RISK FOR TSTMS IS INCRG PER GOING LIGHTING DATA AND RAP INSTABILITY PROFILES. GENERALLY EXPECT IFR/MVFR CONDITIONS TO DOMINATE THIS EVENING WITHIN THE RAIN WITH LOCALIZED PERIODS OF LIFR PSBL IN TSTMS...ESP AT KSAV. THE RAIN IS XPCTD TO DEPART KSAV ROUGHLY BY 04Z AND 07Z AT KCHS...PLUS OR MINUS AN HOUR OR SO. GUIDANCE IS SIMILAR ON SHOWING LOW STATUS FILLING IN ERLY MON WITH CIGS DROPPING AS LOW AS LIFR PRIOR TO SUNRISE. CIGS WILL BE SLOW TO LIFT MON MRNG...BUT ANTICIPATE CONDITIONS RETURNING TO MVFR BY LATE MRNG/ERLY AFTN. EXTENDED AVIATION OUTLOOK...MORE SUB VFR CEILINGS AND VISIBILITIES EXPECTED MONDAY NIGHT AND THEN LESSER CHANCES TUESDAY NIGHT. && .MARINE... A TIGHTENING SURFACE PRESSURE GRADIENT BETWEEN A RIDGE OF HIGH PRESSURE CENTERED N/W OF THE WATERS AND A SURFACE WAVE OF LOW PRESSURE EJECTING ENE FROM THE GULF OF MEXICO WILL SUPPORT INCREASING ONSHORE FLOW AND BUILDING SEAS THIS EVENING. THEN... WINDS WILL SHIFT TOWARD THE S/SW AS THE SURFACE LOW PUSHES INTO THE WATERS OVERNIGHT. HOWEVER...FORECAST CONFIDENCE REMAINS RATHER LOW DUE TO A WEAKER THAN EXPECTED GRADIENT LATE SUNDAY AFTERNOON...AN UNCERTAIN GRADIENT RESPONSE AS THE SURFACE LOW APPROACHES FROM THE NORTHERN GULF TONIGHT AND UNCERTAINTY REGARDING THE EXACT TRACK OF THE SURFACE LOW. RAISED A SMALL CRAFT ADVISORY FOR THE GA WATERS BEYOND 20 NM TO ACCOUNT FOR AN ELEVATED POTENTIAL FOR GUSTS TO 25 KT AND 6 FT SEAS TONIGHT...AND CAPPED WINDS AT 15-20 KT AND SEAS AT 3-5 FT ELSEWHERE. HOWEVER...GRADIENTS COULD BECOME TIGHTER THAN EXPECTED SUPPORTING HIGHER WINDS/LARGER SEAS THAN CURRENTLY FORECAST ACROSS NEARSHORE WATERS TONIGHT. MONDAY THROUGH FRIDAY...THE LOCAL WATERS WILL BE UNDER THE INFLUENCE OF ATLANTIC HIGH PRESSURE AND MODERATE ONSHORE FLOW THROUGH MUCH OF THE WEEK. EXPECT DECENT A DECENT SEABREEZE EACH AFTERNOON ALONG AND COAST AS LAND AREAS WARM. WINDS WILL BECOME SOUTHERLY THURSDAY NIGHT AND FRIDAY AHEAD OF A COLD FRONT. SMALL CRAFT ADVISORY WINDS/SEAS MAY DEVELOP AHEAD OF THE FRONT...THEN PERSIST IN ITS WAKE ON SATURDAY AS WINDS SHIFT TO NNE. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...SMALL CRAFT ADVISORY UNTIL 5 AM EDT MONDAY FOR AMZ374. && ST
