Area forecast discussion 
National Weather Service Peachtree City Georgia 
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 Georgia 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 northwest flow 
expected to affect the area Wednesday night into Thursday so will 
maintain low-chance pops across north Georgia 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 precipitable waters  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-broken deck) but still 
remain generally VFR. 


//Atl confidence...18z update... 
high all elements.
