DISCUSSION
KEY MESSAGE 1...TEMPERATURES WELL ABOVE NORMAL THURSDAY THROUGH
SATURDAY WITH HEAT INDICES OVER 100 DEGREES.
KEY MESSAGE 1 DESCRIPTION...STRENGTHENING MID-LEVEL RIDGE WILL
RESULT IN TEMPERATURES WELL ABOVE NORMAL THU THROUGH SAT. THE
WARMING BEGINS TODAY, BUT TEMPERATURES WILL JUMP AROUND 5 DEGREES
FOR MOST AREAS ON THU. PEAK OF THE HEAT WILL BE FRI WHEN MID-LEVEL
RIDGING(EVEN THOUGH IT WEAKENS SLIGHTLY) COMBINES WITH WESTERLY
FLOW. THIS WILL KEEP THE SEA BREEZE PINNED AND LEAD TO A LITTLE
DOWNSLOPE FLOW/COMPRESSIONAL WARMING. RIDGING CONTINUES TO WEAKEN
SAT AS A FRONT MOVES IN FROM THE NORTHWEST. INCREASED CLOUD COVER
AND WEAKENING 5H RIDGE KEEP TEMPERATURES A LITTLE COOLER SAT, BUT
STILL ABOVE NORMAL. CONTINUES TO LOOK LIKE HEAT INDICES WILL FLIRT
WITH 105 AT SOME POINT THU-SAT, BUT HAVE LOW CONFIDENCE IN DURATION
AND AREAL COVERAGE. SOMETHING TO KEEP AN EYE ON THE NEXT FEW
DAYS.
KEY MESSAGE 2...LIMITED RAIN CHANCES UNTIL THE ARRIVAL OF A COLD
FRONT THIS WEEKEND.
KEY MESSAGE 2 DESCRIPTION...DESPITE INCREASING TEMPERATURES AND
DEWPOINTS CREEPING INTO THE 70S (SEE KEY MESSAGE #1) RAIN CHANCES
WILL BE LIMITED INTO THE WEEKEND. RIDGING ALOFT IN PLACE INTO FRI
WITH ONLY A WEAK SHORTWAVE TO THE NORTH SLIGHTLY DENTING THE RIDGE
THIS AFTERNOON/EVENING. MID-LEVEL ENVIRONMENT REMAINS UNFAVORABLE
FOR STORMS WITH AN ABUNDANCE OF DRY AIR ALOFT, SUBSIDENCE AND POOR
LAPSE RATES. CANNOT RULE OUT SOME ISOLATED CONVECTION ALONG THE SEA
BREEZE AND PIEDMONT TROUGH, BUT COVERAGE WILL BE LIMITED BY THE
LACKLUSTER ENVIRONMENT. ABOUT THE ONLY PARAMETER WORKING IN FAVOR OF
CONVECTION WILL BE SURFACE BASED INSTABILITY, WITH SBCAPE PUSHING 1K
J/KG THU/FRI. MID-LEVEL RIDGING DOES START TO WEAKEN FRI, WHICH MAY
OPEN THE DOOR FOR A FEW MORE STORMS, BUT IT'S ALSO QUITE LIKELY THAT
THE RIDGE DOESN'T WEAKEN QUITE AS QUICKLY AND FRI REMAINS MORE OR
LESS DRY.
SURFACE BASED INSTABILITY HANGS AROUND SAT, WHEN A COLD FRONT MOVES
IN FROM THE NORTHWEST. THE FRONT, WHILE NOT STRONG, WILL PROVIDE
SOME ENHANCED LOW LEVEL CONVERGENCE, COINCIDENT WITH THE SUPPRESSION
OF THE MID-LEVEL RIDGE. ALSO POTENTIAL FOR DEVELOPMENT OF A SURFACE
WAVE ALONG THE FRONT LATER SAT INTO SUN, ENHANCING RAIN CHANCES.
CONFIDENCE DECREASES AFTER SAT WITH THE LOCATION OF THE FRONT AND
MOISTURE AVAILABILITY IN QUESTION. SAT LOOKS TO BE THE BEST CHANCE
FOR RAIN, BUT THERE IS POTENTIAL FOR THE 5H PATTERN TO SHIFT FROM
RIDGING TO TROUGHING WHICH WOULD OPEN THE DOOR FOR A PERIOD OF
UNSETTLED WEATHER EARLY NEXT WEEK.
AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
VFR ALONG THE COAST WITH MVFR SETTING UP INLAND. MVFR CEILINGS
AT FLO/LBT ARE A RESULT OF LEFT OVER MOISTURE FROM EARLIER
CONVECTION ALONG THE SC COAST MOVING NORTH. COASTAL TERMINALS
WILL REMAIN VFR WITH THE ENHANCED LOW LEVEL MOISTURE STAYING
INLAND FROM THE COAST.
GENERALLY VFR TODAY, ONCE INLAND SITES RISE OUT OF MVFR (MID TO LATE
MORNING). LIMITED COVERAGE OF STORMS TODAY, LESS SO THAN TUE GIVEN
THE INCREASING UNFAVORABLE ENVIRONMENT AND HAVE NO MENTION OF
STORMS AT ANY OF THE TERMINALS. SOUTHWEST WINDS UNDER 10KT
TODAY AT INLAND SITES WITH THE SEA BREEZE LEADING TO A LITTLE
MORE ONSHORE FLOW FOR COASTAL TERMINALS. SPEEDS WILL ALSO BE
ENHANCED BY THE SEA BREEZE.
EXTENDED FORECAST...RESTRICTIONS FROM ISOLATED AFTERNOON/EVENING
STORMS POSSIBLE THROUGH FRIDAY, MAINLY INLAND. INCREASED DAYTIME
COVERAGE OF STORMS THIS WEEKEND WILL INCREASE POTENTIAL FOR
RESTRICTIONS AT ALL SITES. OTHERWISE VFR.
MARINE
SOUTHWEST FLOW CONTINUES INTO THE WEEKEND WITH BERMUDA HIGH IN
PLACE. GRADIENT BETWEEN THE HIGH AND THE DEVELOPING PIEDMONT TROUGH
WILL ENHANCE WIND SPEEDS, ESPECIALLY THU AND FRI. NEARSHORE SPEEDS
WILL BE 15-20 KT WITH A SOLID 20 KT WELL OFFSHORE. WEAK COLD FRONT
DROPS IN FROM THE NORTHWEST SAT, BUT STRUGGLES TO MOVE OFFSHORE. THE
BOUNDARY MAY END UP LAYING PARALLEL TO THE FLOW ALOFT JUST NORTH OF
THE WATERS. SOUTHERLY FLOW CONTINUES SAT, BUT WEAKENS WITH THE FRONT
IN THE AREA LEADING TO A POORLY DEFINED GRADIENT. IF THE FRONT SLIPS
SOUTH OF THE WATERS AT ANY POINT SAT/SUN THEN NORTHERLY FLOW WOULD
SET UP, BUT WEAK GRADIENT AND THE LACK OF A STRONG PUSH WILL KEEP
SPEEDS 10-15 KT AT MOST. IF THE FRONT REMAINS TO THE NORTHWEST
SUN, ENHANCED SOUTHERLY FLOW WOULD BE POSSIBLE FOR THE START OF
NEXT WEEK. SEAS 2-3 FT BUILD TO 3-4 FT LATER THU BEFORE
DROPPING BACK TO 2-3 FT THU NIGHT. CYCLE REPEATS ON FRI WITH 2-3
FT SEAS RETURNING FRI NIGHT THEN DROPPING TO AROUND 2 FT WITH
OCCASIONAL 3 FT FOR THE WEEKEND.
