NWS Charleston, SC wrote its last area forecast discussion before the first event at Jun 7, 5:56 PM EST, 2 hours 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 656 PM EDT FRI JUN 7 2013 .SYNOPSIS... POST TROPICAL STORM ANDREA WILL CONTINUE TO MOVE FARTHER NORTH OF THE AREA TONIGHT. ATLANTIC HIGH PRESSURE WILL THEN BUILD INTO THE REGION THROUGH EARLY NEXT WEEK WHILE A TROUGH PERSISTS INLAND. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... INCREASED POPS ACROSS INTERIOR SOUTHEAST GEORGIA TO 50 PERCENT FOR THE NEXT HRS. KJGX RADAR SHOWS A NUMBER OF CONVECTIVE OUTFLOWS THAT WILL COLLIDE AND POTENTIALLY FOCUS SHOWER/TSTM ACTIVITY ROUGHLY WITHIN THE METTER-MILLEN-ALLENDALE-HAMPTON CORRIDOR THROUGH SUNSET. ADDITIONAL ACTIVITY MAY DEVELOP AFTER SUNSET AS SHORTWAVE ENERGY APPROACHES. ITS UNCLEAR BASED ON THE VARIOUS HIGH RESOLUTION SHORT RANGE MODELS EXACTLY HOW MUCH COVERAGE WILL OCCUR AFTER SUNSET AND BOUNDARY COOLING INITIATES. MAINTAINED 30-40 PERCENT MOST AREAS THROUGH MID-EVENING...DIMINISHING TO SLIGHT CHANCE AFTER MIDNIGHT. AN ISOLATED STRONG TSTM IS CERTAINLY POSSIBLE BUT SEVERE TSTMS APPEAR UNLIKELY ATTM. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/... SATURDAY AND SATURDAY NIGHT...HIGH PRESSURE AT THE SURFACE AND ALOFT WILL BUILD INTO THE REGION FROM THE WESTERN ATLANTIC. IT APPEARS THAT THE DEEP LAYERED MOISTURE WILL BE SOMEWHAT LACKING WITH PRECIPITABLE WATER VALUES DOWN BELOW 1.5 INCHES. WHILE LOW LEVEL MOISTURE WILL BE SUFFICIENT TO PRODUCE A FAIRLY EXTENSIVE CUMULUS FIELD AHEAD OF THE SEA BREEZE IN THE AFTERNOON/EARLY EVENING...THE LIMITED MOISTURE SHOULD KEEP ANY CONVECTION ISOLATED IN COVERAGE INLAND FROM THE COAST. LATER SATURDAY NIGHT...CONVECTION IS EXPECTED TO DEVELOP OVER THE ADJACENT COASTAL WATERS AND A FEW SHOWERS AND THUNDERSTORMS COULD WORK THEIR WAY ONSHORE AND IMPACT COASTAL AREAS GIVEN THE FAVORABLE TRAJECTORIES. TEMPERATURES SHOULD REACH HIGHS IN THE UPPER 80S TO AROUND 90 INLAND FROM THE IMMEDIATE COAST DURING THE DAY WITH LOWS AROUND 70 OR IN THE LOWER 70S SATURDAY NIGHT. SUNDAY AND MONDAY...DEEP LAYERED RIDGING WILL PREVAIL OVER THE WESTERN ATLANTIC...WHILE A TROUGH DIGS INTO THE UPPER MISSISSIPPI VALLEY SUNDAY THEN EAST OF THE MISSISSIPPI VALLEY MONDAY. THE SOUTHERLY RETURN FLOW ALONG THE WESTERN PERIPHERY OF THE RIDGE WILL ALLOW DEEP MOISTURE TO ADVECT INTO THE REGION...WITH PRECIPITABLE WATER VALUES SURGING TO NEAR 2.0 INCHES. DAYTIME HEATING WILL CAUSE SCATTERED CONVECTION TO INITIATE BY LATE MORNING AND CONTINUE INTO THE EVENING HOURS BOTH DAYS. WEAK STORM MOTIONS COMBINED WITH THE ABUNDANT MOISTURE COULD RESULT IN HEAVY RAINFALL CAPABLE OF PRODUCING LOCALIZED FLOODING. THE FOCUS OF THE CONVECTION WILL ONCE AGAIN SHIFT TO OVER THE ADJACENT COASTAL WATERS LATE SUNDAY NIGHT...BUT SOME COULD MOVE ONSHORE AND AFFECT COASTAL AREAS. HIGHS WILL BE IN THE UPPER 80S TO AROUND 90 WITH LOWS IN THE UPPER 60S TO LOWER 70S. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... MODELS REMAIN IN AGREEMENT THAT MID LEVEL TROUGHING WILL PERSIST THROUGH TUESDAY...BEFORE A SURFACE COLD FRONT SHIFTS THROUGH THE FORECAST AREA LATE TUESDAY INTO WEDNESDAY. CHANCES OF SHOWERS/THUNDERSTORMS WILL BE POSSIBLE UNTIL THE COLD FRONT PASSES. A WARMING TREND IS THEN EXPECTED FOR THE SECOND HALF OF THE WEEK...AS STRONG RIDGING DEVELOPS TO THE WEST AND GRADUALLY EXPANDS OVER THE DEEP SOUTH. TEMPS WILL PEAK IN THE LOW 90S AWAY FROM THE COAST...WITH POSSIBLY MID 90S BY THE WEEKEND. TYPICAL SUMMERTIME CONVECTION IS ANTICIPATED LATE WEEK GIVEN THE AMOUNT OF SURFACE HEATING EACH DAY...ESPECIALLY ALONG AN INLAND MOVING SEABREEZE. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... VFR. WATCHING TSTMS MOVING IN FROM THE SW OUT OF S-CNTRL GA. ATTM IT APPEARS THIS ACTIVITY WILL REMAIN JUST TO WEST OF THE KCHS-KSAV CORRIDORS...BUT TRENDS WILL BE MONITORED. ATTM WILL LEAVE ALL MENTION OF TSTMS OUT OF THE 00Z TERMINAL FORECASTS. EXTENDED AVIATION...LOW CHANCES OF MORNING STRATUS/FOG AND AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS THROUGH EARLY NEXT WEEK. && .MARINE... TONIGHT...CONDITIONS CONTINUE TO IMPROVE ACROSS THE LOCAL MARINE AREA. CANCELLED THE SMALL CRAFT ADVISORY FOR THE GEORGIA OFFSHORE WATERS. FLAGS WERE MAINTAINED FOR THE CHARLESTON COUNTY COASTAL WATERS FOR A FEW MORE HOURS. SATURDAY THROUGH TUESDAY...ANDREA WILL CONTINUE TO TRACK TO THE NORTHEAST AND AWAY FROM THE REGION THIS WEEKEND...LEADING TO IMPROVING WIND/SEA CONDITIONS OVER ALL WATERS WHILE ATLANTIC HIGH PRESSURE BUILDS OVER THE REGION. EXPECT WINDS/SEAS TO REMAIN WELL BELOW SMALL CRAFT ADVISORY CONDITIONS THROUGH THE MIDDLE OF THE WEEK AHEAD OF A COLD FRONT APPROACHING FROM THE NORTHWEST LATE TUESDAY. IN GENERAL...SOUTH/SOUTHWEST WINDS WILL REMAIN AT OR BELOW 15 KT...HIGHEST NEAR SEABREEZE CIRCULATIONS...WITH SEAS NO HIGHER THAN 5 FT...HIGHEST OVER OUTER GEORGIA WATERS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...SMALL CRAFT ADVISORY UNTIL 2 AM EDT SATURDAY FOR AMZ350. && ST
