AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC ISSUED BY NATIONAL WEATHER SERVICE WILMINGTON NC 339 PM EDT FRI JUL 10 2015 .SYNOPSIS... A WEAK AREA OF LOW PRESSURE INLAND WILL EDGE CLOSER TO THE AREA TONIGHT...WHILE SUB-TROPICAL HIGH PRESSURE PREVAILS ACROSS THE WESTERN ATLANTIC. A COLD FRONT WILL APPROACH SATURDAY NIGHT THEN DISSIPATE...BRINGING A SLIGHTLY BETTER CHANCE OF RAIN. AN INLAND TROUGH WILL REDEVELOP THROUGH MUCH OF THE UPCOMING WEEK WITH A SLIGHT CHANCE OF THUNDERSTORMS EACH DAY. && .NEAR TERM /THROUGH TONIGHT/... DEEP HIGH PRESSURE IS VERTICALLY STACKED FROM THE SURFACE UP THROUGH 300 MB ACROSS GEORGIA AND SOUTH CAROLINA. INLAND...THE PIEDMONT TROUGH EXTENDS SOUTHWARD FROM A WEAK LOW OVER NORTHERN NORTH CAROLINA INTO COASTAL GEORGIA. THIS WEAK TROUGH IN ASSOCIATION WITH THE BERMUDA HIGH OFFSHORE WILL MAINTAIN A LIGHT SOUTHWEST WIND ACROSS THE AREA OVERNIGHT. 850 MB TEMPERATURES EXCEEDING +20C THIS AFTERNOON HAVE ALLOWED SURFACE TEMPS TO REACH THE MID TO UPPER 90S VIRTUALLY EVERYWHERE AWAY FROM THE BEACHES AND IMMEDIATE COAST. CONSIDERABLE DRY AIR ALOFT ACROSS SOUTH CAROLINA HAS CAUSED A LACK OF CUMULUS CLOUDS... WHILE BETTER DEPTH OF MOISTURE ACROSS COASTAL GEORGIA IS ALLOWING MORE CLOUDS AND EVEN SOME SCATTERED SHOWERS TO DEVELOP. THIS ENVIRONMENT IS DIAGNOSED IN REAL-TIME QUITE WELL ON THE SPC MESOANALYSIS WEBPAGE USING THE LCL-LFC RELATIVE HUMIDITY DISPLAY. THESE SHOWERS SHOULD BE SHORT-LIVED AS THEY ARE KEYED STRONGLY TO DIURNAL HEATING...AND SHOULD DISSIPATE BETWEEN 6-8 PM WITH MOSTLY CLEAR SKIES EXPECTED OVERNIGHT. GFS AND NAM MOS ARE TIGHTLY CLUSTERED AT ALL STATIONS TONIGHT AND APPEAR QUITE REASONABLE GIVEN RECENT HISTORY AND THE WARM HUMID AIRMASS IN PLACE. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... PRIMARY WEATHER HEADLINES THIS WEEKEND REMAIN THE ABOVE NORMAL DAYTIME TEMPERATURES...AND A SLIGHTLY BETTER PROSPECT OF RAINFALL AS MID-LEVEL MOISTENING OCCURS. STEERING FLOW OVER THE WEEKEND WILL TRANSITION TO A WNW FLOW ALOFT...ALLOWING SHORT-WAVE ENERGY TO MIGRATE OVER THE NE QUADRANT OF A DAMPENING UPPER RIDGE. THIS SHOULD ENHANCE LOCAL CONVERGENCE ALONG THE SEA-BREEZE BOUNDARY. ALTHOUGH MOSTLY ISOLATED IN COVERAGE...A FEW STORMS COULD BECOME STRONG TO SEVERE SATURDAY...BY LATE AFTERNOON THROUGH EVENING. ANOTHER BATCH OF SHORT-WAVE ENERGY WILL ARRIVE INTO LATE SUNDAY. THE COMBINATION OF AIR TEMPERATURES AND ABSOLUTE HUMIDITY WILL RESULT IN APPARENT TEMPERATURES/HEAT INDICES OF 100-105 ACROSS THE FORECAST AREA BOTH SATURDAY AND SUNDAY. && .LONG TERM /MONDAY THROUGH FRIDAY/... A LARGE MID/UPPER LVL RIDGE OF HIGH PRESSURE WILL REMAIN CENTERED OVER THE SOUTH CENTRAL UNITED STATES AS A MID LVL TROUGH STRENGTHENS OVER THE EASTERN CONUS...ABSORBING A TUTT LOW CURRENTLY OVER THE BAHAMAS. AT THE SFC...THE PATTERN WILL FEATURE A PIEDMONT TROUGH INLAND WHILE THE AXIS OF ATLANTIC HIGH PRESSURE BECOMES POSITIONED FURTHER SOUTHEAST OF THE AREA. THE SETUP SHOULD FAVOR GREATER COVERAGE OF SHOWERS/THUNDERSTORMS OVER THE SOUTHEASTERN UNITED STATES INTO THURSDAY AS A SOUTHWEST FLOW BUILDS DEEPER MOISTURE TO THE AREA AT THE SAME TIME THE INLAND TROUGH INCHES TOWARDS THE SOUTHEAST COAST. MID LVL RIDGING SHOULD THEN BUILD FROM THE WEST BY THE WEEKEND...LIMITING OVERALL PRECIP COVERAGE. OVERALL HIGH TEMPS SHOULD REMAIN A DEGREE OR TWO COOLER THAN PREVIOUS DAYS GIVEN AN INCREASED CHANCE OF PRECIP OVER THE AREA...BUT SHOULD STILL RANGE IN THE LOW TO MID 90S...WARMEST OVER INLAND AREAS IN SOUTHEAST GEORGIA. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... AS OF 18Z...EXPECT VFR THROUGH THE VALID TAF PERIOD. THOUGH BERMUDA HIGH PRESSURE REIGNS ACROSS THE AREA...WOULD NOT ENTIRELY RULE OUT AN ISOLATED SHRA/TSRA THIS AFTERNOON. HOWEVER...CONFIDENCE IS TOO LOW ATTM AND THUS HAVE NOT INTRODUCED IN GOING FORECAST. SOME GUIDANCE CONTINUES TO SUGGEST THE POTENTIAL FOR MARGINAL MVFR FOG TOWARDS SATURDAY MORNING...BUT GIVEN INCREASED WINDS WITHIN THE BOUNDARY LAYER...DO NOT ANTICIPATE FOG DEVELOPMENT. EXPECT SOUTHWEST WINDS AOB 10 KTS THROUGH THE VALID TAF PERIOD...WITH FEW/SCT MID TO HIGH CLOUDS. EXTENDED AVIATION OUTLOOK...MAINLY VFR CONDITIONS ARE EXPECTED TO PREVAIL INTO EARLY NEXT WEEK. && .MARINE... NEAR TERM /THROUGH TONIGHT/... BERMUDA HIGH PRESSURE OFF THE COAST PLUS A WEAK TROUGH AXIS INLAND FROM THE COAST WILL HELP DIRECT A SOUTHWESTERLY WIND ACROSS THE COASTAL WATERS OVERNIGHT. THE STRONGEST WIND SPEEDS WILL LIKELY OCCUR ALONG THE CHARLESTON COUNTY COASTLINE AND NORTHWARD DUE TO INCREASING DISTANCE FROM THE HIGH PRESSURE RIDGE. THIS AFTERNOON'S SEABREEZE CIRCULATION HAS BACKED WIND DIRECTIONS AROUND TO THE SOUTH NEAR THE COAST...BUT AS THIS CIRCULATION DIES AWAY LATE THIS EVENING LOOK FOR THESE WINDS TO VEER BACK TO THE SOUTHWEST. SUSTAINED WIND SPEEDS AROUND 15 KNOTS ARE EXPECTED FOR THE SOUTH CAROLINA COASTAL WATERS...WITH 10-15 KT EXPECTED FOR GEORGIA. SEAS CURRENTLY 3 FEET OUT AT THE EDISTO BUOY MAY BUILD BY AS MUCH AS ANOTHER FOOT BY LATE THIS EVENING DUE TO INCREASING SOUTHWEST WINDS. CLOSER TO SHORE SEAS OF 2-3 FEET ARE ANTICIPATED OVERNIGHT...MAINLY IN 4-5 SECOND WIND WAVES WITH A TOUCH OF SOUTHEASTERLY SWELL. SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...A MANAGEABLE WEEKEND MARINE ENVIRONMENT IN STORE ACROSS THE COASTAL WATERS. MODERATE SW WINDS SATURDAY WILL LIGHTEN INTO SUNDAY AND MAY EVEN BRIEFLY SHIFT TO N-NE AS A WEAK FRONT SLIPS SOUTHWARD AND DISSIPATES ACROSS THE CHARLESTON HARBOR AREA SUNDAY AND SUNDAY NIGHT. A FEW TSTMS ARE POSSIBLE LATE SATURDAY THROUGH SUNDAY AND MARINERS ARE ENCOURAGED TO OBTAIN A RADAR UPDATE BEFORE VENTURING OUT THIS WEEKEND. SEAS A MIX OF SSW WAVES 1-2 FT EVERY 5 SECONDS...AND ESE WAVES AROUND 2 FT EVERY 9 SECONDS BOTH SATURDAY AND SUNDAY. LONG TERM /MONDAY THROUGH WEDNESDAY/... THE COASTAL WATERS WILL THEN REMAIN SITUATED BETWEEN HIGH PRESSURE OVER THE WESTERN ATLANTIC AND A TROUGH OF LOW PRESSURE INLAND INTO THE MIDDLE OF NEXT WEEK. IN GENERAL...SOUTH/SOUTHWEST WINDS WILL REMAIN AT OR BELOW 15 KTS NEXT WEEK...BUT SHOULD PEAK AROUND 20 KTS NEAR SEABREEZE CIRCULATIONS AND NOCTURNAL SURGES...ESPECIALLY AS THE PRESSURE GRADIENT BECOMES ENHANCED MONDAY THROUGH WEDNESDAY. WE COULD SEE A FEW 25 KT WIND GUSTS DURING NOCTURNAL SURGES EACH NIGHT EARLY NEXT WEEK. SEAS WILL RANGE BETWEEN 1-3 FT THIS WEEKEND...THEN GRADUALLY BUILD TO 2-4 FT. WE COULD SEE 5 FT SEAS IN OUTER GEORGIA WATERS DURING NOCTURNAL SURGES. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && NEAR TERM...TRA SHORT TERM...MJC LONG TERM...JDW AVIATION...SGL/TRA
