DISCUSSION
KEY MESSAGE 1: PREVAILING HIGH PRESSURE WILL YIELD MINIMAL RAIN
CHANCES THROUGH MID-WEEK WITH ABOVE NORMAL TEMPERATURES.
ZONAL FLOW EARLY WEEK WILL TRANSITION TO A STRENGTHENING RIDGE
PATTERN ALOFT, WHILE SFC HIGH PRESSURE HOLDS ACROSS THE LOCAL AREA
FOR MUCH OF THE WEEK. THE PATTERN WILL SUPPORT A WARMING TREND AS A
RESULT, WITH LATEST GUIDANCE SUPPORTING HIGH TEMPS IN THE LOW-MID
80S AWAY FROM THE COAST (SEA BREEZE INFLUENCES) TUESDAY THROUGH
THURSDAY. CONDITIONS ARE ALSO EXPECTED TO REMAIN DRY FOR A BULK OF
THE WEEK, ALTHOUGH WEAK H5 VORT ENERGY COULD HELP PRODUCE LIGHT
PRECIP ACTIVITY ACROSS THE INTERIOR WEDNESDAY AFTERNOON.
A COLD FRONT COULD APPROACH THE REGION LATE IN THE WEEK, BRINGING A
HIGHER POTENTIAL FOR MEASURABLE RAINFALL THIS UPCOMING WEEKEND.

VFR CONDITIONS WILL PREVAIL AT CHS/JZI/SAV TERMINALS THROUGH 12Z
TUESDAY.
EXTENDED AVIATION OUTLOOK: VFR CONDITIONS ARE EXPECTED AT

POSSIBLE AT ALL TERMINALS WITH DAILY SHOWERS AND/OR THUNDERSTORMS

WEATHER PATTERN ACROSS THE SOUTHEAST UNITED STATES, FAVORING

SUBSIDE ACROSS OUTER GEORGIA WATERS, WHERE A SMALL CRAFT ADVISORY
REMAINS IN EFFECT INTO TUESDAY MORNING.
EXTENDED MARINE: HIGH PRESSURE WILL PERSIST ACROSS THE REGION
THROUGH LATE WEEK, SUPPORTING WINDS/SEAS THAT REMAIN BELOW SMALL
CRAFT ADVISORY CONDITIONS. THE EXCEPTION WILL BE ACROSS OUTER GA
WATERS, WHERE 6 FT SEAS COULD LINGER INTO MID MORNING HOURS TUESDAY,
THEN POSSIBLY REBUILD TO 6 FT AGAIN THURSDAY NIGHT INTO FRIDAY AS A
FRONT APPROACHES THE SOUTHEAST UNITED STATES LATE WEEK.
