SYNOPSIS
HIGH PRESSURE WILL PREVAIL THROUGH EARLY NEXT WEEK. A COLD
FRONT WILL MOVE THROUGH THE AREA MID WEEK.

EARLY THIS MORNING: VERY QUIET CONDITIONS THROUGH SUNRISE AS
HIGH PRESSURE PROVIDES PLENTY OF DRY AIR AND CLEAR SKIES ACROSS
THE REGION. THERE IS STILL SOME LINGERING NEAR SURFACE MOISTURE,
AND IT ISN'T OUT OF THE QUESTION TO SEE SOME SHALLOW GROUND FOG,
ESPECIALLY ACROSS INTERIOR SOUTHEAST GEORGIA. OTHERWISE, GOOD
RADIATIONAL COOLING CONDITIONS WILL PRODUCE LOW TEMPERATURES IN
THE LOW TO MID 40S.
SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/
DRY HIGH PRESSURE WILL EXPAND OVER THE AREA SATURDAY AND
SUNDAY, THEN MOVE OFFSHORE ON MONDAY. SEASONABLE TEMPS EXPECTED,
WITH HIGHS INCREASING A COUPLE DEGREES EACH DAY. STRONG
RADIATIONAL COOLING EXPECTED SATURDAY NIGHT, ALLOWING TEMPS TO
DIP INTO THE UPPER 30S FAR INLAND AND LOWER TO MIDDLE 40S CLOSER
TO THE COAST.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
DRY HIGH PRESSURE WILL PERSIST INTO MONDAY NIGHT, THEN A FEW
SHORTWAVES WILL MOVE THROUGH TUESDAY AND WEDNESDAY, ACCOMPANIED
BY SCATTERED SHOWERS. A STRONG COLD FRONT WILL MOVE THROUGH
WEDNESDAY NIGHT. A DRASTIC DROP IN TEMPERATURES IS EXPECTED,
WITH HIGHS IN THE MID/UPPER 70S TUESDAY AND WEDNESDAY, DROPPING
INTO THE 50S THURSDAY.
