AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
848 PM EDT FRI MAY 23 2014

.SYNOPSIS...
A COLD FRONT WILL DROP THROUGH THE AREA OVERNIGHT WITH HIGH PRESSURE
BUILDING BEHIND IT SATURDAY. THE HIGH WILL SHIFT INTO THE WESTERN
ATLANTIC ON SUNDAY AND REMAIN THE DOMINANT FEATURE THROUGH THE FIRST
PART OF NEXT WEEK BEFORE A COLD FRONT MOVES IN MID WEEK.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
THE 00Z KCHS STILL SHOWS A 2-3C CAP IN THE LOW LEVELS OF THE ATMOSPHERE.
WHILE THIS COULD BE ASSOCIATED WITH THE MARITIME AIRMASS BEHIND
THE SEA BREEZE...IT IS ALSO VERY LIKELY THAT THIS SAME CAP EXISTS
ELSEWHERE AND IS RESPONSIBLE FOR KEEPING CONVECTION AT BAY ACROSS
THE AREA AS OF EARLY THIS EVENING. HOWEVER...700-500 MB LAPSE RATES
ARE AN IMPRESSIVE -8C.

OUR MAIN FOCUS IS ON CONVECTION STRENGTHENING UPSTREAM ACROSS THE
NORTHERN/CENTRAL MIDLANDS AHEAD OF A SUBTLE SHORTWAVE TROUGH.
THESE THUNDERSTORMS HAVE A HISTORY OF PRODUCING VERY LARGE HAIL
AND DAMAGING WINDS. THESE STORMS SHOULD MAINTAIN INTENSITY AS THEY
NEAR THE AREA GIVEN FORCING ASSOCIATED WITH THE SHORTWAVE ALOFT
AND A MODERATELY TO STRONGLY UNSTABLE AIR MASS IN PLACE ACROSS THE
AREA. IN FACT...SURFACE BASED CAPE VALUES ARE STILL UPWARDS OF 2500
J/KG AND LI/S DOWN TO -9 ACROSS PARTS OF THE CHARLESTON TRI-COUNTY
AREA.

AT THIS TIME IT APPEARS THE CONVECTION SHOULD AFFECT MAINLY PARTS
OF THE CHARLESTON QUAD-COUNTY AREA THROUGH ABOUT MIDNIGHT. AS A
RESULT...SEVERE THUNDERSTORM WATCH 178 HAS BEEN EXTENDED IN TIME
UNTIL MIDNIGHT FOR CHARLESTON...BERKELEY AND DORCHESTER COUNTIES. THE
PRIMARY THREATS REMAIN VERY LARGE HAIL UP TO AROUND 2 INCHES IN
DIAMETER AND DAMAGING WINDS.

LATER TONIGHT THE BACK DOOR COLD FRONT WILL DROP THROUGH THE AREA
WITH DRIER AIR AND NORTHERLY WINDS.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
SATURDAY AND SATURDAY NIGHT...A BACKDOOR COLD FRONT WILL CONTINUE TO
DROP WELL SOUTH OF THE AREA AS SURFACE HIGH PRESSURE BUILDS IN FROM
THE OHIO VALLEY. A RELATIVELY DRY NORTHERLY FLOW WILL PREVAIL
THROUGH MUCH OF THE DAY AT THE SURFACE AND OVERALL MOISTURE WILL BE
INSUFFICIENT TO SUPPORT ANY PRECIPITATION ACROSS THE AREA. A SHORT
WAVE DISTURBANCE EMBEDDED WITHIN NORTHWEST FLOW ALOFT SHOULD BRING
SOME MID AND HIGH LEVEL CLOUDS INTO THE AREA LATER IN THE DAY AND
DURING SATURDAY NIGHT. TEMPERATURES WILL BE COOLER THAN PREVIOUS
DAYS...BUT DOWNSLOPE FLOW JUST ALOFT COULD STILL SUPPORT HIGHS IN
THE MID TO UPPER 80S ACROSS SOUTHEAST SC AND UPPER 80S TO AROUND 90
ACROSS SOUTHEAST GEORGIA. A ROBUST SEABREEZE SHOULD KEEP
TEMPERATURES ALONG THE IMMEDIATE COAST CONSIDERABLY COOLER. WITH THE
INCREASE IN CLOUD COVER AND A LIGHT ONSHORE SYNOPTIC FLOW DEVELOPING
SATURDAY NIGHT...LOWS SHOULD BE IN THE LOWER TO MID 60S.

SUNDAY AND SUNDAY NIGHT...SURFACE HIGH PRESSURE WILL SHIFT INTO THE
WESTERN ATLANTIC...SUPPORTING A SYNOPTIC ONSHORE FLOW ACROSS THE
AREA RESULTING IN AN INCREASE IN LOW LEVEL MOISTURE. FORCING
PROVIDED BY SHORT WAVE ENERGY EMBEDDED WITHIN THE NORTHWEST FLOW
ALOFT AND CONVERGENCE ALONG/AHEAD OF THE SEABREEZE SHOULD SUPPORT
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS...MAINLY ALONG AND
WEST OF THE I-95 CORRIDOR IN THE AFTERNOON AND EARLY EVENING.
MODERATE INSTABILITY WITH CAPE VALUES AS HIGH AS 1500-2500 J/KG AND
LI/S DOWN TO -7 TO -8C...HIGHEST ACROSS INTERIOR SOUTHEAST GA...
SHOULD BE SUFFICIENT FOR PULSE-TYPE ISOLATED SEVERE THUNDERSTORMS TO
OCCUR. ISOLATED CONVECTION COULD RE-FOCUS OVER THE COASTAL WATERS
LATE SUNDAY NIGHT. HIGHS ON SUNDAY SHOULD BE IN THE MID TO UPPER 80S
AWAY FROM THE COAST WITH LOWS SUNDAY NIGHT IN THE MID TO UPPER 60S.

MONDAY...A MOIST SOUTHERLY RETURN FLOW WILL DEVELOP AROUND ATLANTIC
HIGH PRESSURE. MEANWHILE...A LEE SIDE TROUGH INLAND AND THE SEA
BREEZE WILL ACT AS FOCI FOR MAINLY AFTERNOON/EVENING SCATTERED
SHOWERS AND THUNDERSTORMS. MODERATE INSTABILITY PARAMETERS ONCE
AGAIN LOOK FAVORABLE FOR ISOLATED PULSE SEVERE THUNDERSTORMS ALONG
AND AHEAD OF THE SEA BREEZE. HIGHS WILL BE IN THE UPPER 80S ACROSS
MUCH OF THE AREA AWAY FROM THE IMMEDIATE COAST.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
GENERALLY NORTHWEST FLOW ALOFT WILL PREVAIL THROUGH THE PERIOD. A
COLD FRONT SHOULD MOVE INTO THE AREA IN THE MID WEEK TIME FRAME AND
LIKELY STALL OUT. EXPECTED WIDELY SCATTERED TO SCATTERED MAINLY
AFTERNOON AND EVENING THUNDERSTORMS ALONG AND WEST OF THE SEA BREEZE
EACH DAY...WITH THE GREATEST COVERAGE LIKELY ON WEDNESDAY AS THE
COLD FRONT MOVES IN. ABOVE NORMAL TEMPERATURES ARE EXPECTED TUESDAY
AND WEDNESDAY AND THEN MORE NORMAL TEMPERATURES ARE LIKELY THURSDAY
AND FRIDAY.

&&

.AVIATION /01Z SATURDAY THROUGH WEDNESDAY/...
KCHS...UPSTREAM CONVECTION COULD AFFECT THE TERMINAL LATE THIS
EVENING INTO THE EARLY OVERNIGHT HOURS. FOR NOW...HAVE INCLUDED A
TEMPO GROUP FOR THUNDERSTORMS WITH ERRATIC WINDS AND SOME FLIGHT
RESTRICTIONS FROM 03-05Z...BUT AMENDMENTS WILL LIKELY BE NEED TO
ADJUST THE TIME AS TRENDS BECOME BETTER ESTABLISHED.
OTHERWISE...VFR CONDITIONS ARE EXPECTED...WITH WINDS SHIFTING
NORTHERLY BEHIND A COLD FRONT LATER TONIGHT.

KSAV...VFR CONDITIONS ARE EXPECTED TO PREVAIL. WINDS WILL SHIFT
NORTHERLY LATE TONIGHT BEHIND A COLD FRONT.

EXTENDED AVIATION OUTLOOK...TEMPORARY FLIGHT RESTRICTIONS POSSIBLE
WITH MAINLY AFTERNOON/EARLY EVENING CONVECTION SUNDAY THROUGH
MID-WEEK. OTHERWISE...VFR CONDITIONS ARE EXPECTED TO PREVAIL.

&&

.MARINE...
CONDITIONS OVER THE WATERS WILL REMAIN FAIRLY QUIET THROUGH THE
MIDDLE OF NEXT WEEK. HIGH PRESSURE WILL BUILD IN ON SATURDAY AND
THEN SHIFT INTO THE ATLANTIC ON SUNDAY WHERE IT WILL PREVAIL
THROUGH MID-WEEK. THERE WILL BE A BIT OF A NORTHEAST SURGE
SATURDAY MORNING IN THE WAKE OF A COLD FRONT DROPPING SOUTH OF THE
AREA...BUT WIND SPEEDS SHOULD BE NO GREATER THAN ABOUT 15-20 KT.
ANOTHER COLD FRONT COULD ENTER THE WATERS DURING THE MID WEEK
PERIOD. WINDS/SEAS ARE EXPECTED TO BE BELOW ANY HEADLINE CRITERIA
THROUGH THE PERIOD.

&&

.CLIMATE...
CHS HAS HIT 97 DEGREES WHICH BREAKS THE RECORD HIGH FOR THE DATE.

RECORD HIGH TEMPS TODAY...
