AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
417 PM EDT SAT JUN 21 2014

.SYNOPSIS...
A BACKDOOR FRONT WILL DRIFT SOUTH INTO THE REGION TONIGHT THROUGH
SUNDAY. THE FRONT WILL STALL AND THEN DISSIPATE EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
CONVECTION HAS BEEN SLOW TO DEVELOP ACROSS THE FORECAST AREA BY
LATE AFTERNOON DESPITE NOTABLE HEAT...HUMIDITY...AND IMPRESSIVE
LOW LEVEL INSTABILITY. THIS DELAY IS POSSIBLY DUE TO SUBSIDENCE
AND/OR NEGATIVE VORTICITY ADVECTION DOWNSTREAM OF A SHORTWAVE TO
THE NORTHWEST...AS WELL AS ALONG THE PERIPHERY OF A WEAK LOW
SYSTEM OFF THE FLORIDA COAST. THE STRONGEST CONVECTION BY 4 PM EDT
APPEARS MORE ASSOCIATED WITH THE SHORTWAVE ENERGY TRACKING TO THE
SOUTHEAST FROM THE UPSTATE REGION...RATHER THAN FROM THE MORE
TYPICAL SEABREEZE FORCING. A FEW NUMERICAL MODELS EVEN SUGGEST
THAT BEST CONVECTIVE COVERAGE COULD BE EITHER DELAYED OR EVEN
SUPPRESSED UNTIL LATER THIS EVENING...WHEN THE MORE ROBUST ENERGY
ALOFT CAN BREAK THROUGH ANY LIMITING ENVIRONMENT. THESE MORE
CONSERVATIVE MODEL SOLUTIONS ALSO HINT THAT THE MOST ENHANCED
ORGANIZATION/STRENGTHENING OF ACTIVITY COULD BE AFTER SUNSET
ACROSS NORTHERN SECTIONS OF THE FORECAST AREA...CLOSEST TO
SYNOPTIC SCALE CONVERGENCE AND FORCING FROM THE DESCENDING
SURFACE TROUGH AND EMBEDDED BACKDOOR FRONT.

DUE TO UNCERTAINTIES IN TIMING AND COVERAGE FOR THE NEXT SEVERAL
HOURS...HAVE CAPPED THUNDERSTORM CHANCES AROUND 40
PERCENT...HIGHEST ACROSS THE CHARLESTON TRI COUNTY REGION. WILL
MAINTAIN 20 PERCENT POPS THROUGH MIDNIGHT FOR MAINLY THE
INTERSTATE 95 CORRIDOR AND COASTAL COUNTIES...AS THE DESCENDING
FRONT AND PASSING SHORTWAVE ENERGY COULD PROVIDE SUFFICIENT
FORCING TO MAINTAIN NOCTURNAL ACTIVITY. PREFER TO STILL INDICATE A
DIMINISHING TREND FROM WEST TO EAST AFTER MIDNIGHT FOLLOWING THE
BOUNDARY TOWARD THE COASTLINE.

ANY CONVECTION THAT INITIATES THROUGH THE LATE DAY PERIOD WILL BE
ABLE TO TAP INTO SIGNIFICANT AMOUNTS OF LOW LEVEL INSTABILITY AND
STEEP LOW LEVEL LAPSE RATES. CONDITIONS COULD STILL SUPPORT OCCASIONAL
PULSE SEVERE THUNDERSTORMS WITH DAMAGING WET MICROBURSTS...ESPECIALLY
WHERE BOUNDARY/STORM CELL INTERACTIONS OCCUR. PRECIPITABLE WATER
VALUES AROUND 2 INCHES AND RELATIVELY SLOW/OCCASIONALLY ERRATIC
THUNDERSTORM PROPAGATION DUE TO WEAK STEERING FLOW AND COMPLEX
OUTFLOW INTERACTIONS WILL ALSO SUPPORT LOCALLY EXCESSIVE RAINFALL.
THE POTENTIAL FOR A FEW SEVERE THUNDERSTORMS...LOCALLY HEAVY RAIN
AND EXCESSIVE LIGHTNING WILL BE ADDRESSED WITHIN THE HAZARDOUS
WEATHER OUTLOOK. INSTABILITY WILL GRADUALLY WANE OVERNIGHT...AND
LATEST THINKING IS THAT SEVERE THREAT WILL ALSO DIMINISH BY LATE
EVENING WITH ANY LINGERING ACTIVITY.

WILL MAINTAIN THE ONGOING HEAT ADVISORY THROUGH EARLY
EVENING...OR AT LEAST UNTIL CONVECTION CREATES LOCAL COOLING
WITHIN ITS WAKE. TEMPERATURES WILL FALL INTO THE LOW TO MID 70S
OVERNIGHT.

LIGHT WINDS AND DECENT LOW LEVEL MOISTURE POOLING WITHIN THE
FRONTAL TROUGH COULD SUPPORT AREAS OF FOG/STRATUS DURING THE PRE-
DAWN HOURS. HOWEVER...COVERAGE AND INTENSITY OF FOG WILL DEPEND
HEAVILY ON THE THE LOCATION/AMOUNT OF EARLIER RAINFALL. SINCE
THERE IS STILL QUITE A BIT OF UNCERTAINTY REGARDING CONVECTIVE
TRENDS...PREFER TO KEEP FOG OUT OF THE FORECAST AT THIS TIME.
SUBSEQUENT FORECASTS WILL BE ABLE TO BETTER ADDRESS FAVORED AREAS
FOR ANY FOG AND/OR STRATUS.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/...
SUNDAY...A LARGE/EXPANSIVE MID LVL RIDGE OF HIGH PRESSURE OVER THE
SOUTHEASTERN UNITED STATES WILL GRADUALLY RETREAT TO THE GULF OF
MEXICO WHILE A SUBTLE H5 SHORTWAVE SHIFTS OVER THE AREA FROM THE
NORTHWEST. AT THE SFC...A WEAK BACKDOOR FRONT WILL APPROACH FROM THE
NORTH AND STALL OVER THE AREA. THE PATTERN WILL FAVOR SLIGHTLY
COOLER TEMPS THAN THE PREVIOUS DAY...ALTHOUGH A WEAK WESTERLY WIND
COULD OFFSET COOLER TEMPS. 1000-850 MB THICKNESS VALUES SUPPORT HIGH
TEMPS IN THE LOW/MID 90S AWAY FROM THE IMMEDIATE COAST. PWATS NEAR
2.0 INCHES WILL SUPPORT AFTERNOON SHOWERS AND/OR THUNDERSTORMS
CAPABLE OF HEAVY RAINFALL...WITH PERHAPS SOME ENHANCEMENT IN OVERALL
COVERAGE AND INTENSITY OF ACTIVITY ALONG OR NEAR THE STALLED
BOUNDARY WHERE SBCAPES APPROACH 2000-3000 J/KG. ALTHOUGH WIDESPREAD
SEVERE WEATHER IS NOT ANTICIPATED...WE COULD SEE A FEW SEVERE
THUNDERSTORMS DURING AFTERNOON/EVENING HOURS BEFORE STRONGER
ACTIVITY WANES WITH SUNSET. A FEW SHOWERS AND/OR THUNDERSTORMS COULD
PERSIST INTO OVERNIGHT HOURS WITH ABUNDANT MOISTURE AVAILABLE.
OVERNIGHT LOWS SHOULD REMAIN MILD...IN THE LOW/MID 70S INLAND TO
UPPER 70S ALONG THE COAST.

MONDAY AND TUESDAY...THE PATTERN WILL REMAIN UNSETTLED AS ABUNDANT
MOISTURE FUELS SHOWERS AND/OR THUNDERSTORMS DURING PEAK HEATING
HOURS EACH AFTERNOON. ALTHOUGH THE MID/UPPER LVL PATTERN IS NOT
PARTICULARLY IMPRESSIVE IN REGARDS TO FORCING...MODELS SUGGEST A
WEAK AREA OF LOW PRESSURE DEVELOPING OVER THE SOUTHEAST ON MONDAY
AHEAD OF A WEAK TROUGH OF LOW PRESSURE THAT EVENTUALLY APPROACHES
FROM THE NORTHWEST/NORTH ON TUESDAY. CONVECTIVE ACTIVITY APPEARS
TO BE HIGHEST ON MONDAY ALONG THE STALLED BOUNDARY DRAPED OVER THE
FORECAST AREA...BEFORE COVERAGE BECOMES SLIGHTLY LESS BY TUESDAY AS
THE BOUNDARY DISSIPATES OR LIFTS NORTH OF THE AREA. A WEAK WESTERLY
FLOW WILL CONTINUE TO SUPPORT WARMER WEATHER. LATEST 1000-850 MB
THICKNESS VALUES SUPPORT OVERALL HIGH TEMPS IN THE LOW 90S AWAY
FROM THE COAST. A FEW LOCATIONS COULD REACH THE MID 90S WELL INLAND.
OVERNIGHT LOWS SHOULD RANGE BETWEEN THE LOW 70S INLAND TO MID/UPPER
70S ALONG THE COAST.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
OVERALL THIS PERIOD IS EXPECTED TO TRANSITION BACK TO A MORE
CLIMATOLOGICAL NORM WITH REGARD TO RAIN CHANCES. HIGHS SHOULD BE
FAIRLY CLOSE TO NORMAL VALUES...WITH OVERNIGHT LOWS RUNNING A
COUPLE DEGREES ABOVE NORMAL.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP LATER THIS
AFTERNOON...HOWEVER SIGNIFICANT UNCERTAINTY REMAINS CONCERNING
TIMING AND COVERAGE. HAVE NARROWED DOWN EXPLICIT MENTION OF TSRA
DOWN TO 2 HOURS AT BOTH TAF SITES...WHILE MAINTAINING VCTS THROUGH
EARLY EVENING. AMENDMENTS WILL LIKELY BE NEEDED AS CONVECTIVE
TRENDS BECOME MORE APPARENT IN THE NEXT FEW HOURS. SEVERAL
NUMERICAL MODEL SOLUTIONS SUGGEST THAT SHOWERS/THUNDERSTORMS COULD
PERSIST INTO AT LEAST THE EVENING HOURS AS A BACKDOOR FRONT SLIPS
INTO THE AREA OVERNIGHT. IF THIS SCENARIO VERIFIES...THEN
SUBSEQUENT TAF ISSUANCES MAY NEED TO ACCOUNT FOR LINGERING
CONVECTIVE IMPACTS. DEPENDING ON RAIN COVERAGE...PATCHY FOG COULD
DEVELOP DURING THE PRE-DAWN HOURS...AND HAVE TRENDED TOWARD THIS
POSSIBILITY WITH 6SM BR AT BOTH TAF SITES.

EXTENDED AVIATION OUTLOOK...MODERATE CHANCES OF MVFR CIGS/VSBYS
EACH AFTERNOON DUE TO SHOWERS AND/OR THUNDERSTORMS. PATCHY MVFR
CEILINGS AND VSBYS POSSIBLE LATE SUNDAY NIGHT AND MONDAY NIGHT.

&&

.MARINE...
TONIGHT...A BACKDOOR FRONT WILL ADVANCE INTO THE MARINE ZONES. WINDS
WILL VEER TOWARD THE W/NW AT 10 KT OR LESS BEHIND THE DESCENDING
FRONT...WHILE SW WINDS AS HIGH AS 15 TO 20 KT WILL PERSIST SOUTH
OF THE FRONT. THUNDERSTORMS COULD ALTER LOCAL WINDS TONIGHT. SEAS
WILL AVERAGE 2 TO 3 FT.

SUNDAY THROUGH WEDNESDAY...A WEAK BACKDOOR COLD FRONT WILL DRIFT
INTO THE NORTHERN WATERS SUNDAY...THEN STALL OUT ALONG OR NEAR THE
SAVANNAH RIVER ON MONDAY. THE FRONT/BOUNDARY SHOULD THEN LIFT BACK
BACK NORTH OF THE AREA ON TUESDAY. MARINE CONDITIONS ARE EXPECTED TO
REMAIN BELOW SMALL CRAFT ADVISORY LEVELS DURING THIS TRANSITION WITH
WINDS AT OR BELOW 10-15 KT AND SEAS NO HIGHER THAN 3 FEET. THE
PRESSURE GRADIENT WILL THEN BEGIN TO ENHANCE LATE TUESDAY AS A
TROUGH OF LOW PRESSURE APPROACHES THE WATERS FROM THE
NORTHWEST/NORTH. SOMEWHAT STRONGER SOUTH TO SOUTHWEST WINDS...BUT
STILL AT OR BELOW 20 KNOTS WILL OCCUR FROM THE LATER HALF OF TUESDAY
INTO THURSDAY MORNING...WITH THE STRONGEST WINDS OCCURRING DURING
THE NIGHT TIME HOURS. ANOTHER ROUND OF SOMEWHAT STRONGER SOUTH TO
SOUTHWEST WINDS ARE POSSIBLE FROM LATER THURSDAY INTO FRIDAY
MORNING...AGAIN IT APPEARS SPEEDS SHOULD BE AOB 20 KNOTS. ATTM...NO
SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED ACROSS THE COASTAL
WATERS.
