A WEAK LOW-LEVEL VORTICITY CENTER CAN BE SEEN IN A SWIRL OF LOW-
LEVEL CLOUDS OVER SOUTHEAST MISSISSIPPI THIS AFTERNOON, BUT
PREVAILING NORTHERLY FLOW OVER THE REGION WILL REINFORCE DRIER AIR
OVER OUR FORECAST AREA THROUGH THE REMAINDER OF THE WEEKEND.
THE FLOW ALOFT SHOULD AMPLIFY QUICKLY AS AN UPPERL-EVEL RIDGE
OVER THE ROCKIES ELONGATES AND DEEP TROUGHING DIGS OVER THE
EASTERN HALF OF THE CONUS. UPPER-LEVEL HEIGHTS IN THE CORE OF THIS
TROUGH WILL BE ABOUT 2-4 STANDARD DEVIATIONS BELOW NORMAL FOR
THIS TIME OF YEAR - RESULTING IN SUPPRESSED EARLY SEPTEMBER
TEMPERATURES RUNNING ABOUT 5 DEGREES BELOW NORMAL. AND PWAT VALUES
FALLING BELOW 1.5 INCHES SHOULD BRING THE GULF COAST ATMOSPHERE
TO A LITTLE DRIER THAN AVERAGE FOR EARLY SEPTEMBER.
THE BROAD TROUGH OVER THE EASTERN HALF OF THE COUNTRY STILL MEANS
DISTURBANCES COULD BRING SOME CHANCE FOR SHOWERS OR STORMS TO THE
REGION, AND TUESDAY INTO THURSDAY CURRENTLY LOOKS TO BE THE BEST
TIME RANGE FOR THAT TO OCCUR. TIMING AND STRENGTH OF THE WAVE
DETAILS COULD ADJUST THIS WINDOW FOR RAINFALL. /NF/

CEILING AND VISIBILITIES ARE IMPROVING AS EARLIER FOG HAS
DISSIPATED THROUGH THE MORNING, BRINGING MAJORITY OF SITES TO
VFR/MVFR FLIGHT CONDITIONS. CLOUD COVER WILL GRADUALLY CLEAR OUT
OF THE AREA, LEAVING CLEAR SKIES WITH NORTHERLY WINDS NEAR 10 KTS.
VFR FLIGHT CONDITIONS ARE EXPECTED THROUGH THE REST OF THE
PERIOD. /SW/
