KEY MESSAGE 1: ABOVE NORMAL TEMPERATURES EXPECTED TUESDAY THRU
THURSDAY FOLLOWED BY SCATTERED CONVECTION ASSOCIATED WITH THE
NEXT COLD FRONTAL PASSAGE LATE THURSDAY. TEMPS WILL DROP BACK
TO NEAR NORMAL FRIDAY INTO NEXT WEEKEND.
SFC HIGH PRESSURE SLIDES FARTHER OFFSHORE AND EAST OF THE
CAROLINAS TUE THRU THU BUT CONTINUES TO RIDGE BACK TO SOUTHERN
SC. THIS SETUP WILL RESULT IN SW WINDS THRU THE PERIOD. FOLLOWED
BY A NICE WARMUP BACK TO ABOVE NORMAL WITH SUMMER LIKE TEMPS
ESPECIALLY WED AND THU WHERE MID TO UPPER 80S AWAY FROM THE
BEACHES WILL BE COMMON. WITH THE SUN NOW HIER IN THE SKY GIVEN
SUMMER SOLSTICE ROUGHLY 50 DAYS AWAY, DID ADD A FEW DEGREES TO
THE HIGHS FOR MON THRU THU, ESPECIALLY WITH FLOW ALOFT GENERALLY
WESTERLY. A MID-LEVEL S/W TROF DROPPING OUT OF CANADA TO THE
LOWER TO MID MISSISSIPPI RIVER VALLEY WED, WILL DRIVE TO THE
EAST AND AID IN PUSHING A SFC COLD FRONT ACROSS THE ILM CWA
AND OFF THE COAST BY LATE THU. AHEAD OF IT WILL SEE A MODEST
CHANCE FOR CONVECTION ESPECIALLY DURING THE MIDDAY THRU EARLY
EVENING TIME SLOT WHICH WILL AID CONVECTION DEVELOPMENT.
INDIVIDUAL TSTORMS HAVE THE POTENTIAL TO DEPOSIT A DECENT
AMOUNT OF RAINFALL, UNFORTUNATELY IN A MORE LOCALIZED ARENA AS
OPPOSED TO THE PCPN EVENT THIS PAST SUNDAY WHERE IT WAS MORE
WIDESPREAD.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
MAINLY CLEAR SKIES ARE IN PLACE AND WINDS ARE GOING LIGHT OR
CALM ACROSS THE AREA. THESE FACTORS COMBINED WITH ABUNDANT LOW-
LEVEL MOISTURE FROM TODAY'S RAIN WILL RESULT IN TRANSIENT VIS
REDUCTIONS TO AS LOW AS LIFR AT LEAST FOR THE NEXT FEW HOURS
UNTIL WINDS PICK UP AGAIN LATER IN THE NIGHT IN ASSOCIATION WITH
DRIER NEAR-SURFACE AIR FILTERING IN. IN ADDITION, TENDRILS OF
LOW STRATUS ARE DEVELOPING, AND MAY TEMPORARILY IMPACT TERMINALS
WITH LIFR CIGS AT TIMES FOR THE NEXT FEW HOURS. OTHERWISE,
EXPECT VFR TO RETURN BY SUNRISE, IF NOT SOONER, AND CONTINUE
THROUGH THE REMAINDER OF THE PERIOD WITH NORTHWEST WINDS BACKING
THIS AFTERNOON AND GOING LIGHT OR CALM AGAIN AFTER SUNSET.
EXTENDED FORECAST... PREDOMINANTLY VFR THROUGH WEDNESDAY. AN
APPROACHING COLD FRONT ON THURSDAY MAY PRODUCE EARLY-MORNING
STRATUS ALONG WITH TRANSIENT RESTRICTIONS IN SHOWERS OR
THUNDERSTORMS DURING THE DAY.

LATE THU. WINDS WILL INCREASE TO AND ABOVE SCA THRESHOLDS THU
WITH SPORADIC GALE FORCE GUSTS ACROSS THE OFFSHORE WATERS,
AHEAD OF THE APPROACHING COLD FRONT DUE TO THE TIGHTENING SFC
