SYNOPSIS...
A MUCH COOLER AND DRIER AIR MASS HAS SETTLED ACROSS NORTHERN
AND CENTRAL GEORGIA EARLY THIS MORNING. 07-08Z /3-4AM EDT/ TEMPS
RANGED FROM AROUND 50F OVER EXTREME NRN/NW GA TO THE MID 60S
ACROSS THE EXTREME SE AREA OF THE CWA /NEAR VIDALIA/. A BAND OF
BKN TO OVC MAINLY HIGH CLOUDS IS MOVING ACROSS THE REGION AND
SHOULD THIN OUT AND EXIT THE AREA THROUGHOUT THE DAY. NW WINDS
WERE STILL UP A BIT /NEAR 10KTS/ IN SPOTS IN RESPONSE TO GRADIENT
BETWEEN SFC HIGH OVER NE ARKANSAS/WRN TN AND LOW PRESSURE OFF THE
S CAROLINA COAST.

SHORT TERM /TODAY THROUGH SATURDAY/...
HIGH PRESSURE WILL CONTINUE ACROSS THE FORECAST AREA THROUGH
SATURDAY. THE HIGH CENTER IS CURRENTLY ACROSS SOUTHERN MO/NORTHERN
AR. THE HIGH CENTER WILL SHIFT OFFSHORE THE MID ATLANTIC COAST BY

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
UPR RIDGE OF HIGH PRESSURE FIRMLY ENTRENCHED ACROSS THE SOUTHEAST
WILL RESULT IN MAINLY DRY AND SEASONAL CONDITIONS THROUGH SUNDAY.
BY MEMORIAL DAY /MONDAY/...A MORE PREVAILING RETURN /SOUTHEAST/
FLOW WILL INCREASE MOISTURE ACROSS THE STATE AS THE UPR RIDGE AXIS
PUSHES JUST OFF THE GA/FL COAST. AN UPR LVL TROUGH WILL GRADUALLY
APPROACH THE LWR MS VLY BY TUES/WED BUT THE UPR RIDGE APPEARS TO
HOLD STRONG ENOUGH TO DEFLECT THE DEEPER MOISTURE/ENERGY NORTH AND

EAST ACROSS THE FORECAST AREA.
