DISCUSSION
KEY MESSAGE 1: RAIN-FREE CONDITIONS DOMINATE THIS WEEK AS HIGH PRESSURE
PREVAILS.
QUIET CONIDITONS CONTINUE TO PREVAIL ACROSS THE REGION UNDER SFC HIGH
PRESSURE, WITH LATEST OBSERVATIONS SHOWING MOSTLY SUNNY SKIES AND
TEMPERATURES IN THE UPPER 60S TO LOWER 70S. SHOULD SEE THESE VALUES
RISE A BIT MORE THROUGH THE AFTERNOON, AS HIGHS TOP OFF IN THE MID
TO UPPER 70S. EXPECT MUCH OF THE SAME TUESDAY, WITH HIGHS MODERATING
BACK INTO THE MID TO UPPER 80S BY THE END OF THE WEEK AS THE
AFOREMENTIONED HIGH PRESSURE DRIFTS OFFSHORE.
UNFORTUNATELY, NO RAINFALL IS IN THE FORECAST UNTIL LATE THIS
WEEKEND, AND EVEN THAT IS UNCERTAIN. DRY CONDITIONS WILL LEAD TO AN
ENHANCED FIRE DANGER THROUGH THE WEEK, WITH RH VALUES DROPPING LESS
THAN 25% ACROSS INLAND LOCATIONS EVERY AFTERNOON. THAT BEING SAID,
WINDS ONLY LOOK TO PEAK AROUND 10 TO 15 MPH, WHICH SHOULD KEEP THE
THREAT FOR FIRE WEATHER HEADLINES LOW. NONETHELESS, WE ENCOURAGE
FOLKS TO EXERCISE EXTREME CAUTION IF BURNING AND HEED ANY LOCAL BURN
BANS AS CONIDITONS REMAIN VERY DRY.
AVIATION /18Z MONDAY THROUGH SATURDAY/
KCHS/KJZI/KSAV: VFR CONTINUES ACROSS THE AREA. A WEAK SEA BREEZE
WILL SLOWLY ADVANCE INLAND LATE THIS AFTERNOON AND EVENING, TURNING
LIGHT WINDS FROM THE SOUTH.
EXTENDED AVIATION OUTLOOK: DRY HIGH PRESSURE KEEPS VFR CONDITIONS IN
PLACE THROUGH MUCH OF THE COMING WEEK. A SEA BREEZE IS POSSIBLE EACH
AFTERNOON AND EVENING.
MARINE
HIGH PRESSURE CONTINUES TO BUILD OVERHEAD. AS NOTED IN THE PREVIOUS
DISCUSSION, SHOULD SEE BREEZY WINDS QUICKLY DIMINISH THIS AFTERNOON
AS THE SEA BREEZE DEVELOPS. WITH SEAS OF 6 FT STILL POSSIBLE, WILL
CONTINUE THE THE SMALL CRAFT ADVISORY FOR THE OUTER GA WATERS UNTIL
5 PM THIS AFTERNOON. OTHERWISE, EXPECT TRANQUIL CONDITIONS TO
PERSIST FOR THE REMAINDER OF THE WEEK.
RIP CURRENTS: BREEZY NORTHEASTERLY WINDS CONTINUE ALONG THE COAST,
RESULTING IN A STRONG LONGSHORE CURRENT THROUGH MID-DAY. THIS
COMBINED WITH BREAKERS AROUND 3 FT AND LINGERING ELEVATED TIDE
CYCLES WILL KEEP A MODERATE RISK IN PLACE AT ALL BEACHES THROUGH THE
AFTERNOON. DECREASING WINDS AND TIDAL RANGE CYCLES WILL ALLOW THE
RIP CURRENT RISK TO REMAIN LOW TUESDAY AND WEDNESDAY.
CHS WATCHES/WARNINGS/ADVISORIES
GA...NONE.
SC...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 5 PM EDT THIS AFTERNOON FOR AMZ384.
