AREA FORECAST DISCUSSION  
NATIONAL WEATHER SERVICE PEACHTREE CITY GA  
257 PM EDT TUE JUL 16 2019  
   
SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/
 
 
ANOTHER VERY WARM AFTERNOON ACROSS NORTH AND CENTRAL GEORGIA WITH  
2PM TEMPERATURES RANGING FROM THE UPPER 80S FAR NORTHWEST GA TO  
UPPER 90S IN OUR FAR SOUTHEAST AREAS (EASTMAN/DUBLIN/VIDALIA). LOW  
TO MID-LVL RIDGE OVER THE AREA IS HELPING TO SUPPRESS CONVECTION  
WHICH SHOULD CONTINUE THROUGH THE REMAINDER OF THE AFTERNOON/EVENING  
HOURS.  
 
HEADING INTO TOMORROW (WEDNESDAY), REMNANT ENERGY FROM "BARRY"  
OVER ARKANSAS FINALLY MOVES EAST ACROSS THE TENNESSEE VALLEY AND  
OVER THE SOUTHERN APPALACHIANS. THIS WILL INCREASE THE CHANCE FOR  
SHOWERS AND A FEW THUNDERSTORMS MAINLY ACROSS NORTH GEORGIA, WITH  
LOCALLY HEAVY RAIN THE PRIMARY THREAT - ESPECIALLY GIVEN THE  
SUB-TROPICAL AIRMASS IN PLACE. SHORTWAVE ENERGY WITHIN NW FLOW  
EXPECTED TO AFFECT THE AREA WEDNESDAY NIGHT INTO THURSDAY SO WILL  
MAINTAIN LOW-CHANCE POPS ACROSS NORTH GA DURING THIS TIME.  
 
DJN.83  
   
LONG TERM /THURSDAY THROUGH TUESDAY/
 
 
ONLY TWEEKS MADE TO THE LONG TERM FORECAST. THURSDAY AND FRIDAY HEAT  
INDICES HAVE DROP 1-2 DEGREES WITH THE LATEST GUIDANCE, HOWEVER, WE  
WILL CONTINUE TO BE NEAR HEAT ADVISORY CRITERIA AND CAREFUL  
ATTENTION WILL NEED TO BE MONITORED CAREFULLY GOING INTO THE MIDDLE  
OF THE WEEK. LOW-RESOLUTION MODEL RUNS FOR PRECIPITATION CONTINUE TO  
HAVE DISCREPANCIES, BUT WITH SUBSTANTIAL LOW-LEVEL MOISTURE...GFS  
SHOWING PWATS AROUND 2 INCHES THURSDAY THROUGH SATURDAY...TRAPPED  
UNDER THE BROADER SYNOPTIC RIDGE, WE'VE BUMPED RAIN CHANCES UP  
SLIGHTLY IN AREAS WITH CONCENTRATED MOISTURE AND ACCUMULATIONS  
ACROSS MULTIPLE MODEL RUNS EXIST.

AVIATION...  
18Z UPDATE...  
LITTLE TO NO IMPACT WEATHER FOR ALL 7 TERMINALS EXPECTED OVER NEXT  
24 HOURS. AREA REMAINS BETWEEN WEAK UPR RIDGE TO THE EAST AND REMNANTS  
OF TC BARRY TO THE WEST OVER ARKLAMISS REGION. VFR CONDITIONS WILL  
PREVAIL ACROSS THE AREA THROUGH MIDDAY WEDNESDAY, WITH SFC WINDS  
GENERALLY SOUTH-SOUTHWEST, BECOMING MORE WEST-SOUTHWEST WEDNESDAY.  
SHOULD ALSO SEE AN INCREASE IN LOW LVL (4-6KFT AGL) MOISTURE TOMORROW  
WHICH COULD RESULT IN MORE CLOUD-COVER (SCT-BKN DECK) BUT STILL  
REMAIN GENERALLY VFR.
