NWS Charleston, SC wrote its last area forecast discussion before the first event at Jun 28, 12:56 PM EST, 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 156 PM EDT SUN JUN 28 2015 .SYNOPSIS... A WEAK COLD FRONT WILL STALL ALONG THE COAST LATE TONIGHT BEFORE DISSIPATING ON MONDAY. OTHERWISE...ATLANTIC HIGH PRESSURE WILL RESIDE ACROSS THE AREA WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. && .NEAR TERM /THROUGH TONIGHT/... EARLY THIS AFTERNOON...NO CHANGES TO THE FORECAST FOR THE AFTERNOON. AS WE HAVE REACHED CONVECTIVE TEMPERATURES...SHOWERS AND THUNDERSTORMS HAVE STARTED TO DEVELOP. THE ONLY ADDITIONAL THING TO NOTE IS THAT THE SHEAR IS STRONGER THAN IT WAS YESTERDAY...IN THE 30-35 KNOT RANGE IN THE 0-6 KM LAYER. THIS IS WELL SUPPORTED BY THE 12Z KCHS SOUNDING AS WELL AS THE EFFECTIVE SHEAR PLOTS ON THE SPC MESOANALYSIS PAGE. THIS TYPE OF AMBIENT WIND FIELD COULD RESULT IN SOME INTERESTING STORM STRUCTURES THROUGH THE AFTERNOON. SOME ROTATION IS POSSIBLE WITHIN DISCRETE STORMS AS WELL AS SOME SHORT LINEAR SEGMENTS. THE TORNADO THREAT IS VERY LOW HOWEVER THANKS TO HIGH LCL/LFC HEIGHTS AND THE LACK OF MUCH DIRECTIONAL SHEAR. TONIGHT...MID AND UPPER LEVEL DRIER AIR WILL MOVE IN. THE DRYING...ALONG WITH THE LOSS OF DIURNAL HEATING...SHOULD ALLOW THE CONVECTION TO GRADUALLY WIND DOWN DURING THE EVENING. TEMPS WILL DROP TO LOWER VALUES THAN THEY HAVE IN A WHILE...WHICH IS REALLY ONLY CLOSE TO NORMAL WITH UPPER 60S WELL INLAND AND LOWER TO MID 70S AS YOU GET CLOSER TO THE COAST. && .SHORT TERM /MONDAY THROUGH TUESDAY/... DRIER HIGH PRESSURE WILL AFFECT THE REGION MONDAY WITH DEWPOINTS DROPPING INTO THE 60S DURING THE AFTERNOON. THE COLD FRONT SHOULD BE OFF THE COAST BY THEN BUT THERE WILL BE ENOUGH LOW-LEVEL MOISTURE TO SUPPORT PERHAPS AN ISOLATED SHOWER OR TSTM OVER THE COASTAL WATERS. ELSEWHERE WE DO NOT EXPECT ANY CONVECTION. HIGHS WILL BE 90-93F. ON TUESDAY...THE IN-SITU HIGH PRESSURE WILL BEGIN TO LOSE ITS INFLUENCE AS UPPER SHORTWAVE ENERGY DIGS ACROSS THE CENTRAL GULF COAST REGION. SOUTHERLY LOW-LEVEL FLOW INCREASING DURING THE DAY WILL YIELD INCREASING SURFACE DEWPOINTS. COMBINED WITH TEMPS IN THE LOW TO MID 90S...WE EXPECT ENOUGH INSTABILITY TO ALLOW ISOLATED TO SCATTERED SHOWERS/STORMS TO POP UP. THE GREATER COVERAGE LOOKS TO BE IN SOUTHEAST GA WHERE THETA-E VALUES ARE HIGHER. A SIMILAR PATTERN CONTINUES INTO WEDNESDAY WITH SOME UPPER LEVEL SHORTWAVE ENERGY MOVING THROUGH. HIGHS IN THE LOW TO MID 90S AND DEWPOINTS IN THE LOWER 70S WILL PROVIDE THE NECESSARY INSTABILITY FOR SCATTERED MAINLY AFTERNOON/EVENING SHOWERS AND STORMS. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... A QUASI-ZONAL FLOW WILL AFFECT THE REGION WEDNESDAY NIGHT THROUGH FRIDAY AS A LONGWAVE TROUGH REMAINS POSITIONED TO THE NORTHWEST. HEIGHTS WILL BE INCREASING OVER THE INDEPENDENCE DAY WEEKEND AS THE UPPER RIDGE RESTRENGTHENS OVER THE SOUTHEAST. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BE A BIT HIGHER THURSDAY INTO FRIDAY DUE TO WEAKER CAPPING. DECREASING COVERAGE EXPECTED OVER THE WEEKEND AS THE UPPER RIDGE REBUILDS AND MID-LEVELS WARM. HIGHS WILL BE IN THE LOWER 90S LATE WEEK...INCREASING INTO THE LOW/MID 90S OVER THE WEEKEND. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... SHOWERS AND THUNDERSTORMS ARE DEVELOPING THIS AFTERNOON NEAR THE TERMINALS. BASED ON CURRENT RADAR TRENDS...DIRECT IMPACTS WILL FIRST BE POSSIBLE AT KCHS. THE FORECAST FEATURES TEMPO MVFR TSRA CONDITIONS BETWEEN 18-20Z. THERE IS LESS ACTIVITY CURRENTLY AROUND KSAV...BUT THAT IS EXPECTED TO FILL IN THIS AFTERNOON. TEMPO TSRA CONDITIONS AT KSAV A LITTLE BIT LATER...IN THE 20-22Z TIME PERIOD. OTHER THAN THE THUNDERSTORMS CONDITIONS ARE EXPECTED TO REMAIN VFR. THERE IS AGAIN A CHANCE FOR SOME MVFR CEILINGS TO DEVELOP NEAR SUNRISE ON MONDAY AND LINGER FOR A FEW HOURS. HAVE LEFT THE FORECAST WITH JUST A VFR CEILING FOR NOW. EXTENDED AVIATION OUTLOOK...VFR MONDAY NIGHT. SCATTERED AFTERNOON AND EVENING THUNDERSTORMS TUESDAY THROUGH THURSDAY COULD OCCASIONALLY REDUCE VISIBILITIES AND/OR CEILINGS. && .MARINE... WIND SPEEDS WILL BE A NOTCH BELOW SATURDAY THIS AFTERNOON AND EVENING. THE MAIN CONCERN FOR COASTAL WATERS THIS AFTERNOON AND EVENING IS POTENTIAL FOR STRONG TSTMS PRODUCING SHIFTING AND GUSTING WINDS. WE WILL HIGHLIGHT POTENTIAL FOR CONVECTIVE GUSTS OVER 35 KT IN OUR HAZARDOUS WEATHER OUTLOOK. WINDS AND SEAS WILL LAY DOWN EVEN MORE LATER TONIGHT AS THE WEAK FRONT NEARS. A TYPICAL SUMMERTIME PATTERN WILL ENSUE FOR THE COASTAL WATERS WITH HIGH PRESSURE OVER THE WESTERN ATLANTIC MAINTAINING SOUTHWEST FLOW. THERE WILL BE SURGES ALONG THE COAST EACH AFTERNOON AS THE SEA BREEZE CIRCULATION DEVELOPS. AT NIGHT THE NEARBY ATLANTIC WATERS WILL SEE INCREASING WINDS DUE TO NOCTURNAL JETTING THOUGH CONDITIONS ARE CURRENTLY FORECAST TO REMAIN BELOW ADVISORY THRESHOLDS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && NEAR TERM...BSH SHORT TERM...JRL LONG TERM... AVIATION...BSH/JRL MARINE...JRL
