AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
350 PM EDT FRI JUN 19 2015
.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PREVAIL THROUGH NEXT WEEK WHILE A TROUGH
OF LOW PRESSURE PERSISTS INLAND.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
A STRONG UPPER RIDGE REMAINS IN PLACE...WITH A ROBUST MID-LEVEL
CAP THUS FAR INHIBITING STRONG CONVECTION. THE CUMULUS FIELD ON
VISIBLE SATELLITE IS PRETTY TAME WITH ONLY MODERATE TOWERING
CUMULUS ALONG THE SEA BREEZE IN THE SC TRI-COUNTY AND INLAND
SOUTHEAST GA. SLIGHTLY LOWER HEIGHTS ACROSS OUR INTERIOR GA ZONES
MAY ALLOW FOR SCATTERED CONVECTION TO FIRE UP THROUGH EARLY
EVENING. A POOL OF HIGHER DEWPOINTS ACROSS THE SC TRI-COUNTY AREA
ACCOMPANIED BY THE SEA BREEZE WILL PROVIDE A SECONDARY FOCUS OF
CONVECTION. ELSEWHERE THE CONVECTION WILL BE MORE ISOLATED THOUGH
OUTFLOW BOUNDARIES THROWN INTO COASTAL GA AND SOUTHERN SC MAY
TRIGGER ADDITIONAL ACTIVITY. CANNOT RULE OUT A HANDFUL OF SEVERE
STORMS...DAMAGING WINDS THE GREATEST THREAT GIVEN THE 1200 J/KG
DOWNDRAFT CAPES. THOUGH THE LACK OF APPRECIABLE SHEAR AND
PERSISTENT CAP SHOULD PRECLUDE A GREATER THREAT/COVERAGE FOR
SEVERE STORMS.
RESIDUAL CONVECTION SHOULD TAPER OFF EARLY TO MID EVENING AS THE
BOUNDARY LAYER VERY SLOWLY STABILIZES. THE HEAT ADVISORY DROPS OFF
AT 7 PM...BY WHICH TIME HEAT INDICES SHOULD HAVE DROPPED BELOW
105F. A WARM AND MUGGY NIGHT EXPECTED OTHERWISE...LOWS IN THE MID
TO UPPER 70S.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
ON SATURDAY...THE UPPER RIDGE OVER FLORIDA/SE GEORGIA AND SOUTHERN
SOUTH CAROLINA WILL CONTINUE TO STEER THE SHORTWAVE TROUGH AND IT/S
ASSOCIATED DEEP TROPICAL MOISTURE TO THE NW ACROSS THE TENNESSEE
VALLEY REACHING THE MID ATLC COAST BY MID MORNING SUNDAY. A SLIGHTLY
DRIER 1000-500 MB LAYER IS FORECAST TO MOVE INTO THE FORECAST AREA
DURING THE DAY SATURDAY AND WE THINK THE DAY WILL REMAIN MAINLY
CAPPED AND DRY. HOT TEMPS WILL PERSIST BUT IT LOOKS SURFACE DEW
POINTS HAVE A CHANCE TO MIX OUT SLIGHTLY BETTER...ESPECIALLY INLAND
AREAS. AFTERNOON HEAT INDICES WILL BE IN THE 102-105 DEGREE RANGE
WITH THE SEA BREEZE CORRIDOR EXPECTED TO SEE THE HIGHEST APPARENT
TEMPS BETWEEN 105 AND 108. WE THINK AFTERNOON CONVECTION WILL BE
VERY SPOTTY AND WE MAINTAINED POPS BELOW 20 PERCENT.
SATURDAY NIGHT...WE EXPANDED SOME LOW END CHANCES FOR SHOWERS AND
TSTMS IN N-NW TIER OF ZONES AS THE BASE OF THE MID ATLC SHORT WAVE
BRUSHES BY. LOWS WILL ONCE AGAIN BE IN THE MID 70S WITH UPPER 70S
ALONG THE COAST.
SUNDAY AND MONDAY...HOT AND MOSTLY DRY WEATHER WILL CONTINUE AS THE
OVERALL WEATHER PATTERN CHANGES VERY LITTLE THROUGH THE PERIOD.
SURFACE HIGH PRESSURE WILL PERSIST OVER THE ATLANTIC WHILE A TROUGH
OF LOW PRESSURE SITS INLAND. ALOFT...THE RIDGE WILL STRENGTHEN LATE
THIS WEEKEND INTO MONDAY ENSURING THE LONG DURATION SPELL OF HEAT
GOES ON. ADDITIONAL HEAT ADVISORIES LIKELY BOTH DAYS AS HIGH TEMPS
REACH THE MID/UPPER 90S. LARGE SCALE SUBSIDENCE WILL KEEP DIURNAL
SHOWER/THUNDERSTORM COVERAGE ISOLATED AND MAINLY AS A RESULT OF THE
SEA BREEZE AND/OR CONVERGENCE ALONG THE INLAND TROUGH.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
MID/UPPER LEVEL RIDGE WILL REMAIN ANCHORED OVER THE SOUTHEASTERN
UNITED STATES THROUGH THE PERIOD...MAINTAINING TEMPERATURES WELL
ABOVE NORMAL AND ONLY SLIGHT CHANCES POPS FOR AFTERNOON
CONVECTION. AT THE SURFACE...ATLANTIC HIGH PRESSURE WILL PREVAIL
WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. MAIN CONCERN WILL
BE THE CONTINUING HEAT. HIGH TEMPERATURES OF UPPER 90S TO NEAR 100
WILL COMBINE WITH MODERATE HUMIDITY TO PRODUCE HEAT INDICES
UPWARDS OF 105 DEGREES EACH AFTERNOON. HEAT ADVISORIES WILL LIKELY
BE NEEDED.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
CONVECTION IS SLOW TO INITIATE THIS AFTERNOON DUE TO A FAIRLY
STRONG MID-LEVEL CAP...DESPITE VERY WARM AND MOIST AIR IN LOW
LEVELS. WE INCLUDED VICINITY THUNDERSTORMS AT BOTH SITES THROUGH
LATE AFTERNOON AS THE SEA BREEZE PUSHES INLAND AND COULD POP A FEW
STORMS. QUIET CONDITIONS EXPECTED TONIGHT THROUGH EARLY SATURDAY
AFTERNOON.
EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL.
&&
.MARINE...
ATLANTIC HIGH PRESSURE WILL REMAIN THE DOMINANT FEATURE OVER THE
WATERS WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. A FAIRLY
ROBUST SSW SURGE IS EXPECTED TO DEVELOP OVER THE WATERS SATURDAY
EVENING AS LOW PRES WELL TO THE NORTH ENHANCES THE PRES GRADIENT A
BIT. WIND SPEEDS SHOULD INCREASE TO 15 TO 20 KT WITH SEAS BUILDING
TO 4 FT OUTSIDE THE PILOT BUOYS DOWN TO GRAYS REEF. ADDITIONAL
NOCTURNAL SURGES ARE LIKELY SUNDAY AND MONDAY EVENINGS WITH 15G20
KT AT TIMES. WINDS WILL BE LIGHTEST DURING THE POST-DAWN MORNING
HOURS AS IS TYPICAL WITH THIS SYNOPTIC PATTERN. SMALL CRAFT
ADVISORY CONDITIONS ARE NOT EXPECTED THROUGH THE PERIOD.
