Area Forecast Discussion National Weather Service Peachtree City GA 737 AM EDT Mon Aug 10 2020 .PREV DISCUSSION... /issued 336 AM EDT Mon Aug 10 2020/ SHORT TERM /Today through Tuesday/... A stalled out frontal boundary was the initial impetus for convection across North GA but NW flow transitioned the activity quickly across Central GA where activity is finally dying out. Have kept in low end pops for the remainder of the overnight period as we continue to see some activity from time to time across North GA at this hour. Looks to be an active day across the area as a strong shortwave moves through the Tennessee Valley and into North GA at the prime heating hours. Although instability is not all that impressive in the models, complex should be maintained as it progresses through the forecast area. With precipitable water values around 2 inches and aforementioned marginal instability, will go with likely pops for the entire area. Scattered strong and isolated severe storms will be likely with this activity. Focus will shift to Central GA for Tuesday as shortwave energy progresses past the northern portions. Still enough moisture and instability for all areas to warrant at least low end chance pops but 2.10 PW values over Central GA warrants continued high end chance to low end likely values. With light flow and persistent convection , will need to watch for localized flooding. Generally 100 to 105 for heat indices through the short term and focused on Central GA. Enough to make a mention in the HWO but no advisories needed. Deese LONG TERM /Tuesday Night through Sunday/... A somewhat typical summertime pattern will be in store for the long term highly characterized by weak flow aloft and broad weak surface high pressure with an embedded surface trough across the area. The nature of the upper flow will allow for weak short waves to move to the area that would enhance the chances for showers and thunderstorms along with abundant moisture with daytime instability. The shower and thunderstorm chances will favor the afternoon and evening but not necessarily end at night. The abundant moisture across the area will also lead to heat indices in the 100 to 105 range for at least portions of north and central GA through the weekend, with spotty heat indices of 105 to 110 on Wednesday. BDL && .AVIATION... 12Z UPDATE... Lowcigs and fog continues to affect MCN but should be on the wane through daybreak. Increased moisture will allow for BKN cigs to develop later today but remain VFR except in the vicinity of thunderstorms. Another round of TSRA likely for all sites but perhaps a later start as activity begins over far North GA and translates south through the day. Winds to remain on the west side and light at 10 kts or less. //ATL CONFIDENCE...06Z UPDATE... Medium on TSRA timing. High on remaining elements. Deese && && .PRELIMINARY POINT TEMPS/POPS...
