THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.
.DAY ONE...TODAY AND TONIGHT...
STRONG WINDS CAN BE EXPECTED ACROSS ALL OF NORTH AND CENTRAL
GEORGIA TODAY. SCATTERED THUNDERSTORMS ARE EXPECTED ACROSS
PORTIONS OF CENTRAL GEORGIA LATE THIS EVENING AND OVERNIGHT.
ISOLATED STRONG TO SEVERE THUNDERSTORMS WILL ALSO BE POSSIBLE
ACROSS THIS AREA.
.SYNOPSIS...
A STRONG AREA OF LOW PRESSURE DEVELOPING IN THE SOUTHERN PLAINS
WILL APPROACH THE SOUTHEAST LATER TODAY. MEANWHILE...A COOL WEDGE
OF HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE MID ATLANTIC AND
SOUTHEAST STATES.
.PRIMARY HAZARDS...
BESIDES THE STRONG WINDS THAT WILL DEVELOP ACROSS THE AREA
TODAY...THE PRIMARY HAZARDS ASSOCIATED WITH ANY THUNDERSTORMS
WILL BE DAMAGING WINDS AND CLOUD TO GROUND LIGHTNING. THE BEST
LOCATION FOR THUNDERSTORMS IS GENERALLY ALONG AND SOUTH OF A LINE
FROM HAMILTON...TO FORSYTH...TO ATHENS.
.DISCUSSION...
A STRONG WEDGE OF COOL AIR REMAINS IN PLACE ACROSS NORTHEAST
GEORGIA. A DEVELOPING AREA OF LOW PRESSURE IN THE SOUTHERN PLAINS
WILL CONTINUE TO DEEPEN AND MOVE NORTH TODAY. A NEARLY STATIONARY
FRONT WILL REMAIN IN PLACE ACROSS THE STATE...ON THE SOUTHWEST
EDGE OF THE WEDGE. A COLD FRONT...ASSOCIATED WITH THE LOW...WILL
APPROACH LATE TONIGHT. THE PRESSURE GRADIENT BETWEEN THE HIGH
PRESSURE TO THE NORTHEAST AND THE APPROCHING LOW WILL INCREASE
TODAY...LEADING TO WINDS BETWEEN 15-25 MPH AND GUSTS BETWEEN
30-40 MPH.
AS THE COLD FRONT APPROACHES LATE THIS EVENING...CAPES WILL
INCREASE TO BETWEEN 100 AND 300 ACROSS PORTIONS OF CENTRAL
GEORGIA. WITH THE UPPER-LEVEL SUPPORT PROVIDED BY THE APPROACHING
SYSTEM...THUNDERSTORMS MAY DEVELOP ACROSS CENTRAL GEORGIA. STRONG
VERTICAL WIND SHEAR IN PLACE DUE TO THE WEDGE...WITH EASTERLY
WINDS AT THE SURFACE AND SOUTHWESTERLY WINDS ALOFT...MAY ALLOW
ISOLATED THUNDERSTORMS TO BECOME BRIEFLY SEVERE. STRONG DAMAGING
WINDS AND LIGHTNING WILL BE THE MAIN THREATS...BUT WITH THE STRONG
SHEAR AN ISOLATED BRIEF TORNADO CANNOT BE RULED OUT.
PROLONGED...STEADY RAINFALL THAT WILL DEVELOP THIS AFTERNOON MAY
LEAD TO ADDITIONAL RISES ON ALREADY FULL CREEKS AND RIVERS. SOME
LOCATIONS MAY EXPERIENCE MINOR FLOODING.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
