.AVIATION...
CLEAR SKIES AND LIGHT WIND WILL PROMOTE SOME FOG DEVELOPMENT LATE
TONIGHT. BEST CHANCE FOR IFR FOG WILL BE AT GNV AND POSSIBLY VQQ.
&&
.MARINE...
HIGH PRESSURE RIDGE WILL SHIFT SOUTH ACROSS THE AREA TONIGHT WITH
WINDS TURNING TO THE SOUTHWEST. NOCTURNAL SURGE WILL PUSH WINDS UP
TO AROUND 15 KNOTS OVER THE OFFSHORE. A SMALL CRAFT EXERCISE
CAUTION WILL CONTINUE TONIGHT OVER THE OFFSHORE ZONES DUE TO
LINGERING 4 TO 6 FT SWELLS. LIGHT WINDS ARE EXPECTED ON WEDNESDAY
AND SWELLS WILL CONTINUE TO DECREASE. ANOTHER SMALL CRAFT ADVISORY
EVENT IS EXPECTED WEDNESDAY NIGHT AS CONFIDENCE GRIDS ARE ALREADY
SHOWING A 90% CHANCE OF 20 KNOT WINDS OVER THE OFFSHORE ZONES FROM
ALTAMAHA SOUND TO ST AUGUSTINE.
&&
.FIRE WEATHER...
HOT TEMPERATURES AND WELL MIXED PROFILE WILL SUPPORT LONG
DURATIONS OF SUB 35 PERCENT HUMIDITIES ACROSS MUCH OF THE AREA THE
NEXT 2 DAYS. WINDS WILL REMAIN LIGHT TOMORROW BUT WE MAY NEED A
FIRE DANGER STATEMENT FOR COMBINATION OF ERC AND LOW RH DURATIONS.
WINDS WILL INCREASE QUITE A BIT ON WEDNESDAY AS THE PRESSURE
GRADIENT TIGHTENS BETWEEN A FAST APPROACHING COLD FRONT AND HIGH
PRESSURE TO OUR SOUTH. A FIRE WEATHER WATCH IS NOW IN EFFECT FOR
ALL OF OUR CWA DUE TO STRONG WINDS AND LOW RH. SOUTHWEST WINDS
WILL INCREASE TO 15 TO 20 MPH AND BECOME GUSTY. HUMIDITIES WILL BE
BE MUCH HIGHER ON THURSDAY BUT WILL LOWER AGAIN ON FRIDAY AND
SATURDAY.
