DISCUSSION
KEY MESSAGE 1...WARM AND HUMID CONDITIONS FOR MOST OF THE
UPCOMING SEVEN DAYS WITH FOGGY NIGHTS POSSIBLE.
KEY MESSAGE 1 DESCRIPTION...
THE PATTERN WILL BE SUMMER-LIKE FOR MOST OF THE UPCOMING SEVEN
DAYS. A LOW AMPLITUDE RIDGE EAST OF FL WEDNESDAY WILL BUILD IN
AMPLITUDE AND SIZE. MEANWHILE AT THE SURFACE HIGH PRESSER WILL
BE CENTERED NEAR BERMUDA. THE FORMER WILL SUPPRESS VERTICAL
MOTION AND KEEP US RAIN=FREE UNTIL SOME WEAKENING IS NOTED
STARTING SUNDAY. THE LATTER WILL ACT AS A HEAT AND MOISTURE PUMP
INTO THE CAROLINAS. THE WEST-EAST ELONGATION OF THE HIGH WILL
KEEP WINDS QUITE LIGHT SO MOST NIGHTS WILL BE PRONE TO FOG THAT
COULD BE LOCALLY DENSE ESPECIALLY TOWARDS DAYBREAK, AGAIN
THROUGH ABOUT SUNDAY. IN ADDITION TO THE OVERLAND RADIATIVE FOG
THE NEXT SEVERAL DAYS WILL ALSO FEATURE AN ADVECTIVE MARINE
LAYER-INDUCED FOG (SEE BELOW). WITH LIGHT SSW FLOW OVER THE
CHILLY SSTS PARTS OF COASTAL BRUNSWICK COUNTY COULD HAVE
TROUBLE SHEDDING THE FOG THROUGH THE DAY AND INHIBIT THE
OTHERWISE VERY WARM TEMPERATURES ACROSS THE REST OF THE AREA,
GENERALLY IN THE LOW 80S. EVEN ABSENT THE SEA FOG LINGERING
COASTAL BRUNSWICK COUNTY WILL HAVE TEMPERED WARMTH IN THE
ONSHORE FLOW.
KEY MESSAGE 2...WIDESPREAD MARINE FOG POSSIBLE WEDNESDAY THROUGH
SUNDAY (OR BEYOND).
KEY MESSAGE 2 DESCRIPTION...
WARM AND HUMID CONDITIONS FOR MOST OF THE UPCOMING SEVEN DAYS WITH
FOGGY NIGHTS POSSIBLE.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
WIDESPREAD LIFR TO OPEN THE 12Z TAF PERIOD, DUE TO PATCHY DENSE
FOG. VISIBILITIES WILL GRADUALLY IMPROVE OVER THE NEXT COUPLE OF
HOURS, AND THE FOG LOOKS TO FINALLY MIX OUT OVER LAND BY 14-15Z.
CALM WINDS WILL PICK UP TOWARDS 5-6 KTS OUT OF THE SW, PULLING
MORE S AT THE COAST WHERE A SEABREEZE WILL KICK UP IN THE
AFTERNOON. SEA FOG MAY SPILL OVER INTO KCRE AND KMYR AT TIMES IN
THE AFTERNOON AND EVENING, CREATING POTENTIALLY MVFR TO IFR
CONCERNS. WINDS CALM AFTER SUNSET, WHERE FOG MAY BECOME A
CONCERN ONCE AGAIN AFTER 06Z TONIGHT. DON'T KNOW IF IT'LL BE
QUITE AS WIDESPREAD OR AS DENSE, BUT CONDITIONS STILL LOOK
PRETTY FAVORABLE. LOOK FOR AT LEAST IFR RESTRICTIONS AT THAT
POINT.
EXTENDED FORECAST....VFR CONDITIONS ARE EXPECTED FOR MUCH OF THE
EXTENDED PERIOD BUT PATCHY FOG COULD BRING LATE NIGHT/EARLY MORNING
RESTRICTIONS AND SEA FOG COULD ADVECT INTO THE GRAND STRAND
TERMINALS WEDNESDAY NIGHT THROUGH THE WEEKEND.
MARINE
THROUGH TONIGHT...VARIABLE WINDS AROUND 5 KTS WILL FINALLY BECOME
SOUTHERLY THIS AFTERNOON AT 5-7 KTS, PUSHING A DECENT SEABREEZE
INLAND. SEA FOG ALREADY BECOMING AN ISSUE IN SOME SPOTS,
PARTICULARLY OFFSHORE OF LITTLE RIVER INLET DOWN TO THE SOUTH SANTEE
RIVER. THIS IS EXPECTED TO BECOME MORE WIDESPREAD THROUGHOUT THE DAY
AND INTO TONIGHT. MAY NEED TO ISSUE A MARINE WEATHER STATEMENT AT
SOME POINT TO ADDRESS SOME OF THESE ISSUES. SEAS AROUND 2-4 FT.
THURSDAY THROUGH SUNDAY... HIGH PRESSURE TO BE CENTERED NEAR BERMUDA
FOR THE DURATION OF THE PERIOD. WINDS AND SEAS WILL BE TEMPERED BY
THE FACT THAT THE HIGH WILL BE ELONGATED WEST-EAST, THE RIDGE AXIS
EXTENDING INTO THE CAROLINAS. SW WIND CHOP AND SE SWELL WILL NOT ADD
UP TO MUCH THROUGH MOST OF THE LATE WEEK PERIOD BUT SEA FOG WILL
LIKELY TO CONTINUE TO BE THE MAIN MARINE HAZARD. FLOW AROUND THE
BERMUDA HIGH WILL CONSTANTLY ADVECT HIGH DEWPOINT AIR INTO THE
REGION, GENERALLY IN THE 60S. WITH SSTS BARELY INTO THE 50S THE
STAGE SHOULD BE SET FOR A LONG DURATION OF VISIBILITY RESTRICTIONS.
ILM WATCHES/WARNINGS/ADVISORIES
