KEY MESSAGE 1: AREAS OF LOW STRATUS AND FOG LIKELY THIS MORNING.
AS OF MIDNIGHT A COLD FRONT IS LOCATED TO THE SOUTH OF THE
FORECAST AREA. GOES SATELLITE IMAGERY SHOWS A LARGE AREA OF LOW
STRATUS WORKING SOUTHWARDS ACROSS THE THE FORECAST AREA, WITH
CEILINGS LESS THAN 1K FT ACROSS MOST OF THE REGION. ADDITIONALLY
FOG HAS DEVELOPED IN SOME SPOTS AS DEW POINTS REMAIN ELEVATED.
GENERALLY VISIBILITIES WILL BE BETWEEN 1 AND 3 MILES THROUGH THE
OVERNIGHT PERIOD, HOWEVER BRIEF DROPS TO LESS THAN 1 MILE WILL
BE POSSIBLE. BOTH THE 00Z NBM AND HREF ARE VERY UNSUPPORTIVE OF
THE FOG BECOMING DENSE, WITH PROBABILITIES ONLY AROUND 20% OF
VISIBILITIES LESS THAN 1 MILE. THEREFORE, A DENSE FOG ADVISORY
IS UNLIKELY TONIGHT.

KCHS/KJZI WILL INITIALIZE WITH IFR CIGS FOR THE 12Z TAFS, WITH
MVFR CIGS AT KSAV. CONDITIONS WILL SLOWLY IMPROVE TODAY, WITH
VFR EXPECTED BY THE AFTERNOON HOURS.
EXTENDED AVIATION OUTLOOK: THE NEXT CHANCE OF FLIGHT
RESTRICTIONS IS LATE SUNDAY INTO MONDAY DUE TO A PASSING COLD
FRONT.
MARINE
AREAS OF FOG ARE STILL POSSIBLE EARLY THIS MORNING, HOWEVER
WEBCAM OBSERVATIONS SHOW THAT THE FOG IS NO LONGER DENSE AND THE
MARINE DENSE FOG ADVISORY IN EFFECT FOR THE CHARLESTON HARBOR
HAS BEEN CANCELED. PATCHY FOG WILL LINGER THIS MORNING, HOWEVER
IS EXPECTED TO CLEAR UP BY LATE THIS MORNING/EARLY AFTERNOON.
A DRY COLD FRONT IS EXPECTED TO PUSH THROUGH THE REGION EARLY
NEXT WEEK, BRINGING ELEVATED SEAS AND GUSTS. SMALL CRAFT
ADVISORIES ARE LIKELY ACROSS ALL WATERS, INCLUDING THE
CHARLESTON HARBOR, FROM MONDAY INTO MONDAY NIGHT. NBM
PROBABILITIES OF GUSTS >34 KTS ARE AROUND 35% ACROSS THE
