AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
840 PM EDT MON JUN 9 2014

.SYNOPSIS...
WEAK HIGH PRESSURE WILL PREVAIL THROUGH TUESDAY. A TROUGH OF LOW
PRESSURE WILL THEN DEVELOP OVER THE SOUTHEAST STATES AND PERSIST
THROUGH EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
THE SEA BREEZE IS POISED TO INTERSECT THE ONGOING CONVECTION OVER
ORANGEBURG COUNTY WITHIN THE NEXT HOUR. THIS MAY RESULT IN A
BRIEF INCREASE IN COVERAGE/INTENSITY THROUGH 11 PM...MAINLY ACROSS
NORTHERN DORCHESTER AND MORE LIKELY NORTHERN BERKELEY COUNTY.
ADJUSTED POPS SLIGHTLY TO REFLECT THIS THINKING. DECENT
INSTABILITY WAS STILL NOTED ON THE 10/00Z KCHS RAOB SO AN ISOLATED
SEVERE TSTM IS STILL A POSSIBILITY...MAINLY OVER THE CHARLESTON
TRI-COUNTY AREA.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
TUESDAY...A DEEP UPPER TROUGH OVER THE LOWER MISSISSIPPI VALLEY AT
THE START OF THE DAY WILL STEADILY LIFT NORTHEAST INTO THE OHIO
VALLEY DURING THE EVENING AND NIGHTTIME HOURS. THIS SHIFT WILL
ALLOW A DOWNSTREAM RIDGE TO BRIEFLY BUILD BACK INTO THE SOUTHEAST
STATES...WITH ACCOMPANYING NEGATIVE VORTICITY ADVECTION SLIPPING
INTO MUCH OF GEORGIA AND SOUTH CAROLINA. CONVECTIVE COVERAGE
DURING THE AFTERNOON HOURS COULD THUS BE LIMITED...AS THE BEST
FORCING ALOFT IS CONFINED WEST AND NORTH OF THE FORECAST
AREA. THE SEABREEZE WILL THEN BECOME THE ONLY NOTABLE FOCUS FOR
DEVELOPMENT. HAVE THUS ADVERTISED THE LOWEST RAIN CHANCES OF THE
PERIOD FOR TUESDAY...CAPPING SHOWER/THUNDERSTORM POTENTIAL IN THE
SLIGHT CHANCE RANGE ALONG AND INLAND OF THE SEABREEZE DURING THE
AFTERNOON/EARLY EVENING HOURS. RISING HEIGHTS ALOFT AND CONTINUED
WEST TO SOUTHWEST FLOW WILL SUPPORT ANOTHER HOT AND HUMID
DAY...WITH HIGH TEMPERATURES IN THE MID 90S AWAY FROM THE COAST
AND HEAT INDICES PEAKING AT 100 TO 101 DEGREES ACROSS FAR INLAND
LOCATIONS.

WEDNESDAY...THE TRANSIENT DOWNSTREAM RIDGE WILL QUICKLY DAMPEN
AND SHIFT FARTHER INTO THE ATLANTIC...WHILE THE AXIS OF THE UPPER
TROUGH EXPANDS ACROSS THE EASTERN UNITED STATES. THE SURFACE
PATTERN WILL GRADUALLY TRANSITION INTO A WEAK TROUGH
INLAND...WHILE SHORTWAVE ENERGY ON THE LEADING EDGE OF THE UPPER
LEVEL SYSTEM ALLOWS AN INCREASE IN DEEP LAYER MOISTURE AND REDUCES
ANY LINGERING SUBSIDENCE. WILL CONTINUE TO INDICATE FAIRLY HIGH
CONFIDENCE IN SHOWER/THUNDERSTORM COVERAGE...ESPECIALLY DURING THE
FAVORED AFTERNOON TIME FRAME YET POSSIBLY PERSISTING INTO THE
EVENING/OVERNIGHT HOURS DUE TO THE UPPER LEVEL SUPPORT. HIGH
TEMPERATURES WILL PEAK A DEGREE OR TWO LOWER THAN EARLIER IN THE
WEEK DUE TO CLOUD COVER AND DECREASING HEIGHTS ALOFT.

THURSDAY...THE AXIS OF THE UPPER TROUGH WILL CONTINUE TO SHIFT
TOWARD THE COASTLINE...WITH EMBEDDED SHORTWAVE ENERGY SUPPORTING
THE DEVELOPMENT OF A SURFACE WAVE OF LOW PRESSURE ACROSS THE
CAROLINAS. THESE FEATURES WILL ENHANCE TYPICAL SEABREEZE
CONVECTION AND ONCE AGAIN SUPPORT SCATTERED THUNDERSTORMS ACROSS
THE FORECAST AREA DURING THE FAVORED AFTERNOON/EARLY EVENING TIME
FRAME.

AS IS TYPICALLY THE CASE IN SUMMER-TYPE CONVECTION...MODERATE
INSTABILITY WITHIN WARM AND HUMID CONDITIONS DURING THE AFTERNOON
EACH DAY COULD SUPPORT AN ISOLATED STRONG TO SEVERE
THUNDERSTORM...ESPECIALLY WHERE BOUNDARY INTERACTIONS OCCUR. AT
THIS POINT...DETERMINING SPECIFIC TIMING AND LOCATIONS OF ANY
ORGANIZED CONVECTION IS DIFFICULT AND WILL LIKELY NEED TO BE
HANDLED ON A SHORT TERM BASIS.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
A SOMEWHAT TYPICAL SUMMERTIME PATTERN WILL OCCUR...ALTHOUGH
DAYTIME CONVECTION COULD BE SLIGHTLY ENHANCED THROUGH THE WEEKEND
DUE TO A WEAK LINGERING UPPER TROUGH. TEMPS WILL BE SLIGHTLY
MODERATED BY THE LACK OF APPRECIABLE UPPER HEIGHT RISES...KEEPING
HIGHS AROUND 90 EACH DAY. DUE TO THE WEAK TROUGH EXPECTED TO
LINGER OVER THE AREA THROUGH SUNDAY...HAVE KEPT A SLIGHT CHANCE
POP IN FOR OVERNIGHT HOURS WITH 20 TO 40 POP DURING THE DAYTIME.

&&

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
VFR. SLIGHT CHANCE FOR TSTM IMPACTS AT KCHS 00-03Z...BUT
CONFIDENCE IS LOW.

EXTENDED AVIATION OUTLOOK...MODERATE RISK FOR BRIEF FLIGHT
RESTRICTIONS EACH AFTERNOON/EARLY EVENING DUE TO SHOWERS/TSTMS.

&&

.MARINE...
TONIGHT...THE LOCAL WATERS WILL BE SANDWICHED BETWEEN THE BERMUDA
HIGH TO THE EAST AND A LOW PRESSURE SYSTEM ENTERING THE MID
MISSISSIPPI VALLEY. THIS WILL PROMOTE A GENERAL SOUTHWEST FLOW
ACROSS THE WATERS. OVERALL THE GRADIENT WILL NOT BE ALL THAT TIGHT
SO WIND SPEEDS ARE EXPECTED TO REMAIN LESS THAN 15 KT. SEAS WILL BE
2 FT WITHIN 20 NM AND 2-3 FT BEYOND.

TUESDAY THROUGH SATURDAY...ATLANTIC HIGH PRESSURE WILL REMAIN THE
DOMINANT FEATURE OVER THE MARINE ZONES THROUGH MUCH OF THE
PERIOD...WHILE AN INLAND TROUGH GRADUALLY EDGES CLOSER TO SHORE.
SOUTH TO SOUTHWEST FLOW WILL PREVAIL...WITH MODEST AFTERNOON SEA
BREEZE CIRCULATIONS DEVELOPING ALONG THE COAST.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
