DISCUSSION
KEY MESSAGE 1... ABOVE NORMAL TEMPERATURES AND INCREASED
HUMIDITY WILL CONTINUE THROUGH MUCH OF THIS WEEK. THE POTENTIAL
FOR SHOWERS AND THUNDERSTORMS MAY PROVIDE SOME TEMPORARY RELIEF
FOR SOME AREAS EACH DAY.
BUILDING RIDGE ACROSS THE SOUTHWESTERN ATLANTIC WILL SNEAK INTO
THE CAROLINAS ON WEDNESDAY. WARMER TEMPERATURES ARE EXPECTED TO
RETURN AND WEAK SUBSIDENCE FOLLOWING A SHORTWAVE WILL KEEP
AFTERNOON CONVECTION ISOLATED TO WIDELY SCATTERED. WARM
TEMPERATURES ON WEDNESDAY ARE STILL ONLY SLIGHTLY ABOVE NORMAL
AND INCREASED HUMIDITY COULD PUSH HEAT INDICES UP TO 105 FOR A
BRIEF PERIOD. THE MAIN CONCERN WOULD BE AREAS OF COASTAL SC
PRIOR TO THE DEVELOPING SEA BREEZE.
RIDGING BUILDS ON THURSDAY AND FRIDAY. WESTERLY DOWNSLOPE FLOW
WILL ADD TO THE WARM TEMPERATURES. HIGHS SHOULD EASILY REACH THE
UPPER 90S FOR A LARGE PORTION OF THE AREA. THIS, COMBINED WITH
HIGH HUMIDITY, WILL LIKELY LEAD TO ADDITIONAL HEAT ADVISORIES
LATER THIS WEEK. THE CENTER OF THE RIDGE WILL BE SUPPRESSED TO
OUR SOUTH. MEANWHILE, WEAK SHORTWAVE IMPULSES WILL MOVE THROUGH
THE MID-ATLANTIC BOTH THURSDAY AND FRIDAY. THIS SHOULD SPARK
SOME ISOLATED CONVECTION DESPITE THE DRIER AIR ALOFT.
AVIATION /18Z MONDAY THROUGH SATURDAY/
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO IMPACT THE COASTAL
TERMINALS FOR THE NEXT COUPLE OF HOURS AS THE ACTIVITY SHIFTS
INLAND LATER THIS AFTERNOON. BRIEF RESTRICTIONS ARE EXPECTED AS
THESE STORMS SHIFT INLAND. A FEW STRONG GUSTS ARE POSSIBLE WITH
STORMS. ONGOING OUTFLOWS COULD KEEP ACTIVITY GOING THROUGH THE
EARLY EVENING. A STRONGER LOW LEVEL JET SHOULD KEEP FOG CHANCES
LIMITED TONIGHT, SOME LOW STRATUS IS POSSIBLE. COASTAL TERMINALS
WILL SEE SOME STRATUS TO START THE DAY ON TUESDAY AS THE SEA
BREEZE DEEPENS THROUGH LATE MORNING.
EXTENDED FORECAST... GENERALLY VFR. LOW POTENTIAL FOR
FLIGHT RESTRICTIONS FROM FOG OR LOW CEILINGS EACH MORNING.
THREAT FOR MAINLY AFTERNOON AND EVENING SHOWERS/THUNDERSTORMS
THROUGH LATE THIS WEEK.
MARINE
SOUTHWESTERLY WINDS INCREASE TODAY AS THE BERMUDA HIGH BUILDS
WESTWARD ACROSS THE ATLANTIC. BREEZY SW WINDS ARE EXPECTED WITH
GUSTS UP TO 20 KNOTS POSSIBLE THROUGH THIS EVENING. CHOPPY SEAS
INCREASE TO AROUND 2-3 FEET OVERNIGHT. THE SURFACE PATTERN
REMAINS STABLE ON TUESDAY AND WEDNESDAY AND THE EXTENDED FETCH
LEADS TO AN INCREASE IN SWELL AND WIND WAVES. A COMPRESSED
GRADIENT WILL KEEP BREEZY CONDITIONS THROUGH LATE THIS WEEK.
