SHORT TERM
 
 
(THIS AFTERNOON THROUGH MONDAY)  
ISSUED AT 233 PM EST SUN JAN 29 2023  
 
CURRENT RADAR LOOP SHOWS LIGHT SHOWERS OVER NORTH AND WESTERN  
PORTIONS OF THE STATE WITH MOVE PRECIPITATION MOVING IN FROM AL.  
THIS RAIN IS ASSOCIATED WITH A SLOW MOVING FRONTAL BOUNDARY PUSHING  
THROUGH THE MID MS AND OH RIVER VALLEYS THIS AFTERNOON. DEEP GULF  
MOISTURE IS RIDING AHEAD OF THE FRONT GETTING SOME ADDITIONAL  
ISENTROPIC LIFT THANKS TO CONTINENTAL AIRMASS THAT WAS ALREADY IN  
PLACE AT THE SURFACE. THERE IS A SHORTWAVE ALONG THE FRONT OVER  
SOUTHERN MS/AL THAT WILL MOVE RAPIDLY NE AND PUSH INTO WEST GA RIGHT  
AROUND SUNSET TONIGHT. THIS WAVE WILL PROVIDE ANOTHER KICK OF UPPER  
LEVEL SUPPORT AND MOISTURE INCREASING PRECIP CHANCES OVER NIGHT.  
THE MODELS ARE SHOWING A STRONG PUSH OF RAIN ACROSS THE CWA TONIGHT  
INTO MON AFTERNOON WITH HIGHEST QPF AMOUNTS ACROSS OVER CENTRAL  
GEORGIA. THERE IS ALSO A A LITTLE BIT IF INSTABILITY WITH THIS WAVE  
SO MAY SEE SOME THUNDERSTORMS TONIGHT FOR AREAS SOUTH OF AND ATL TO  
AHN LINE THROUGH MONDAY AFTERNOON. NO SEVERE STORMS ARE EXPECTED  
THROUGH THE PERIOD. OVERALL RAINFALL THROUGH MONDAY MORNING LOOKS TO  
BE AROUND AN INCH ACROSS NORTH GEORGIA AND 1-3" ACROSS CENTRAL  
GEORGIA WITH SOME ISOLATED HIGHER AMOUNTS POSSIBLE ACROSS ALL AREAS.  
PORTIONS OF CENTRAL GEORGIA ARE UNDER A SLIGHT RISK (LEVEL 2 OUT OF  
5) FOR FLASH FLOODING PER WPC WITH MARGINAL RISK (1 OUT OF 5)  
EXTENDING THROUGH THE REST OF CENTRAL GEORGIA AS A RESULT.  
 
SKIES WILL REMAIN MOSTLY CLOUDY THROUGH THE SHORT TERM KEEPING TEMPS  
IN THE 60S DURING THE DAY WITH NIGHT TIME LOWS IN THE 40S AND 50S.

LONG TERM
 
 
(TUESDAY MORNING THROUGH NEXT SATURDAY)  
ISSUED AT 233 PM EST SUN JAN 29 2023  
 
UNSETTLED WEATHER WILL PERSIST THROUGH THE BALANCE OF THE WORK WEEK  
AS THE REGION WILL REMAIN BENEATH SOUTHWEST FLOW ALOFT BETWEEN THE  
COLD AIR TO THE NORTH AND THE BLOCKING SUBTROPICAL RIDGE OVER THE  
GULF. AS WEAK SHORTWAVE DISTURBANCES RIDE NORTHEASTWARD, WAVES OF  
SHOWERS CAN BE ANTICIPATED. THE BALANCE OF THE HIGHER SHOWER  
COVERAGE THROUGH WEDNESDAY WILL BE ACROSS NORTH GEORGIA WITH  
COVERAGE DIMINISHING FARTHER SOUTH. QPF DURING THIS TIME FRAME  
SHOULD BE RELATIVELY LIGHT AS WELL. THE BULK OF THE HEAVIER RAINFALL  
LOOKS TO ARRIVE BY THE LATTER HALF OF THE DAY THURSDAY AS THE  
SHORTWAVE OVER THE SOUTHWEST EJECTS NORTHEASTWARD AND INITIATES THE  
DEVELOPMENT OF A WEAK SURFACE LOW OVER THE NORTHERN GULF STATES.  
THIS SYSTEM WILL TRAVERSE THE AREA THURSDAY NIGHT INTO THE FIRST  
HALF OF FRIDAY AND BRING WIDESPREAD RAINFALL, SOME OF WHICH WILL  
LIKELY BE ON THE HEAVIER SIDE. CURRENT FORECAST TOTALS THROUGH  
FRIDAY RANGE GENERALLY FROM 1-2.5" WITH LOCALLY HIGHER AMOUNTS  
ACROSS NORTH GEORGIA.  
 
A DRIER AND COOLER AIRMASS WILL SETTLE INTO THE AREA BY SATURDAY AS  
A STRONG SURFACE HIGH DROPS FROM THE GREAT LAKES INTO NEW ENGLAND,  
SETTING UP A CAD WEDGE AND DROPPING TEMPERATURES BACK BELOW  
NORMAL.
