NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 12, 12:31 PM EST, 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 131 PM EDT WED AUG 12 2009 .SYNOPSIS... A TROUGH OF LOW PRESSURE WILL PREVAIL OVER THE CAROLINAS AND GEORGIA THROUGH THE UPCOMING WEEKEND. HIGH PRESSURE OVER THE WESTERN ATLANTIC WILL THEN STRENGTHEN EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... WATER VAPOR IMAGERY DEPICTS A DEEP UPPER LEVEL TROUGH DIGGING EAST OF THE MISSISSIPPI VALLEY TODAY...WITH DEEP TROPICAL MOISTURE STREAMING ACROSS THE SOUTHEAST STATES. AT THE SURFACE...A LEE SIDE TROUGH IS IN PLACE ACROSS THE EASTERN MIDLANDS AND EXTENDING INTO EAST-CENTRAL GEORGIA. THE RIGHT ENTRANCE REGION OF A 75-80 KT UPPER LEVEL JET WILL BE POSITIONED OVER THE REGION TODAY ENHANCING DIVERGENCE ALOFT. MEANWHILE...LOW LEVEL CONVERGENCE WILL BE MAXIMIZED ALONG THE LEE SIDE TROUGH...THE INLAND PROGRESSING SEA BREEZE...AND A POTENTIAL DIFFERENTIAL HEATING BOUNDARY WHICH MAY DEVELOP JUST WEST OF THE I-95 CORRIDOR WHERE THERE HAS BEEN A SHARP GRADIENT IN CLOUD COVER THIS MORNING. ALL OF THESE FACTORS WILL SUPPORT THE DEVELOPMENT OF NUMEROUS TO WIDESPREAD SHOWERS AND THUNDERSTORMS THIS AFTERNOON. THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORM DEVELOPMENT THIS AFTERNOON...ESPECIALLY WHERE STRONG HEATING IS TAKING PLACE THIS MORNING. THE MODIFIED 12Z KCHS SOUNDING SHOWS CONSIDERABLE CAPE VALUES THIS AFTERNOON...IN EXCESS OF 4000 J/KG...ALONG WITH LITTLE IF ANY CONVECTIVE INHIBITION. OTHER INSTABILITY PARAMETERS ARE IMPRESSIVE AS WELL...WITH A K INDEX OF 33...TOTAL TOTALS AROUND 49... LIFTED INDICES DOWN TO -9C AND 700-500 MB LAPSE RATES OF -6.5 C/KM. THE PRIMARY SEVERE WEATHER THREAT WILL BE DAMAGING WINDS...WITH DOWNDRAFT CAPE VALUES OF NEARLY 1200 J/KG AND A WINDEX OF 55-60 MPH. THERE IS ALSO A LIMITED RISK OF LARGE HAIL...BUT IT SHOULD NOT BE THE PRIMARY THREAT GIVEN WET BULB ZERO HEIGHTS OF 14K FT AND 500 MB TEMPERATURES OF -7C. HOWEVER...THE STRONGEST UPDRAFTS WILL BE CAPABLE OF PRODUCING LARGE HAIL SO CANNOT RULE IT OUT. HEAVY RAINFALL MAY ALSO BECOME A CONCERN THIS AFTERNOON...GIVEN PRECIPITABLE WATER VALUES OF 2 TO 2.25 INCHES ACROSS THE AREA. WHILE STORM MOTIONS WILL BE 15-20 KT...STORMS TRAINING OVER THE SAME AREA WILL RESULT IN VERY HEAVY RAINFALL AND THE POTENTIAL FOR LOCALIZED FLOODING. FORECAST HIGH TEMPERATURES HAVE BEEN RAISED INTO THE LOWER 90S WHERE SUNSHINE HAS BEEN PREVALENT THIS MORNING...BUT LOWERED INTO THE UPPER 80S WELL INLAND WHERE SKIES HAVE BEEN OVERCAST AND ONLY A FEW BREAKS ARE EXPECTED TO OCCUR THROUGH EARLY AFTERNOON. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/... TSTM ACTIVITY SHOULD BE ON A SIGNIFICANT WEAKENING TREND BY EARLY EVENING AS THE ATMOSPHERE WILL LIKELY BE SIGNIFICANTLY OVERTURNED ACROSS A GOOD PART OF THE REGION BY SUNSET. STILL...MODELS ARE HITTING POPS PRETTY HARD THROUGH MUCH OF THE NIGHT WITH DYNAMICS HOLDING FIRM ASSOCIATED WITH THE UPPER TROUGH. WILL HANG INTO 50 PERCENT POPS THROUGH MIDNIGHT WITH POPS LOWERING TO 20-40 PERCENT THEREAFTER. THERE WILL BE A LINGERING RISK FOR SEVERE TSTMS THROUGH ABOUT 8-9 PM. IT WILL REMAIN QUITE WARM AND MUGGY OVERNIGHT WITH LOWS RANGING FROM THE LOWER 70S WELL INLAND TO AROUND 80 AT THE BEACHES. && .LONG TERM /THURSDAY THROUGH TUESDAY/... MEDIUM RANGE GUIDANCE IS IN FAIRLY GOOD AGREEMENT WITH LARGE SCALE SYNOPTIC FEATURES THIS MORNING. UPPER TROUGHING OVER THE SOUTHEAST STATES THURSDAY AND FRIDAY...WILL BEGIN TO BREAK DOWN OVER THE WEEKEND AS UPPER LEVEL RIDGING BUILDS BACK INTO THEA REGION. UPPER LEVEL RIDGING IS THEN EXPECTED TO HOLD IN PLACE ACROSS THE THE SOUTHEAST CONUS THROUGH EARLY NEXT WEEK. AT THE SURFACE...A TROUGH OF LOW PRESSURE IN THE LEE OF THE APPALACHIANS WILL WEAKEN SLOWLY THROUGH THE END OF THE WEEK...THEN DISSIPATE OVER THE WEEKEND AS ATLANTIC HIGH PRESSURE BUILDS BACK INTO THE AREA. ATLANTIC HIGH PRESSURE IS THEN EXPECTED TO REMAIN THE DOMINANT WEATHER FEATURE THROUGH EARLY NEXT WEEK. AS FOR FORECAST DETAILS...WITH UPPER LEVEL TROUGHING...PLENTY OF DEEP MOISTURE...AND ADEQUATE INSTABILITY IN PLACE ACROSS THE AREA...EXPECTED NUMEROUS SHOWERS/THUNDERSTORMS TO AFFECT THE CWA THURSDAY AND FRIDAY...AND WILL CARRY LIKELY OR HIGH CHANCE POPS ACROSS THE AREA. EXPECT SHOWER/THUNDERSTORM COVERAGE TO SLOWLY DECREASE THROUGH THE WEEKEND INTO EARLY NEXT WEEK AS RIDGING AT THE SURFACE AND ALOFT BEGIN TO BUILD BACK OVER THE REGION...SO WILL KEEP SCATTERED POPS GOING SATURDAY AND SUNDAY BEFORE TAPERING TO SLIGHT CHANCE POPS MONDAY AND TUESDAY. TEMPERATURES AREA EXPECTED TO RUN NEAR TO SLIGHTLY BELOW CLIMATOLOGY THURSDAY THROUGH SATURDAY...THEN NEAR TO SLIGHTLY ABOVE NORMAL SUNDAY THROUGH TUESDAY. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... STRONG INSTABILITY COMBINED WITH DEEP LAYERED MOISTURE...NUMEROUS SURFACE BOUNDARIES AND GOOD UPPER LEVEL SUPPORT WILL RESULT IN NUMEROUS SHOWERS AND THUNDERSTORMS THIS AFTERNOON INTO EARLY THIS EVENING. AS THUNDERSTORMS IMPACT THE TERMINALS...MVFR OR LOWER CONDITIONS ARE EXPECTED TO OCCUR...ALONG WITH GUSTY AND ERRATIC WINDS. TEMPORARY SHOWERS AND THUNDERSTORMS REMAIN IN THE FORECAST FOR BOTH TERMINALS FOR THE 18-22Z TIME FRAME...WITH ADJUSTMENTS AND ADDITIONAL REFINEMENTS TO OCCUR WITH FUTURE AMENDMENTS AS CONVECTIVE TRENDS BECOME BETTER ESTABLISHED. CONVECTION COULD LINER INTO THE EARLY EVENING...BUT OVERALL THERE WILL BE A DIMINISHING TREND WITH THE LOSS OF DAYTIME HEATING. HIGH LEVEL DEBRIS CLOUDINESS COULD PERSIST INTO THE OVERNIGHT HOURS...WITH SOME GUIDANCE SHOWING THE POTENTIAL FOR LOWER CEILINGS TO DEVELOP AROUND DAYBREAK. EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL GENERALLY PREVAIL. HOWEVER...MVFR/IFR CONDITIONS ARE POSSIBLE IN SCATTERED AFTERNOON AND EVENING SHOWERS/THUNDERSTORMS THROUGH MONDAY. && .MARINE... SOUTHERLY WING REGIME WILL HOLD THROUGH TONIGHT WITH SUBTROPICAL HIGH PRESSURE CENTERED WELL OFFSHORE. SPEEDS WILL BECOME ENHANCED ALONG THE LAND/SEA INTERFACE THIS AFTERNOON WITH THE FORMATION OF THE SEA BREEZE...BUT WE DO NOT ANTICIPATE ANY PROBLEMS WITHIN THE CHARLESTON HARBOR TODAY. ANOTHER NOCTURNAL SURGE APPEARS LIKELY AGAIN TONIGHT...ASSUMING SCATTERED TSTMS THAT MOVE OFFSHORE LATER THIS AFTERNOON/EVENING DO NOT SIGNIFICANT DISRUPT THE WIND FIELD. THE HIGHEST WINDS /15-20 KT/ WILL BE CONFINED TO THE GEORGIA OFFSHORE LEG. SEAS WILL REMAIN 2-4 FT THROUGH THE PERIOD. THURSDAY THROUGH SUNDAY...ATLANTIC HIGH PRESSURE WILL PREVAIL...WHILE A TROUGH OF LOW PRESSURE LINGERS IN THE LEE OF THE APPALACHIANS. THIS WILL RESULT IN A TYPICAL SUMMERTIME PATTERN OVER THE COASTAL WATERS...CHARACTERIZED BY AFTERNOON SEA BREEZES AND NOCTURNAL SURGES. WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH THE PERIOD. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && JAQ
