572 FXUS62 KFFC 091135 AFDFFC Area Forecast Discussion...Update for Aviation National Weather Service Peachtree City GA 735 AM EDT Sun Aug 9 2020 .SHORT TERM /Today through Monday/... An upper ridge will build across the southeast through the short term. The remnants of a surface boundary persists across central GA. An unstable air mass and diurnal heating will support isolated to scattered convection this afternoon into the evening...mainly across central GA. Not much change expected for Monday. Slight chance to chance pops for the afternoon with diurnal heating. Somewhat higher pops east central associated with a sea breeze. Models hint at the possibility of a convective complex late tonight into Monday as a short wave moves southeastward from the Mid MS Valley into the southern Appalachians. Have left low pops through the night into Monday morning mainly north GA. Otherwise not confident at this time to try and refine pops any more. Heat Index values are forecast to remain below advisory criteria today and Monday...ranging from 100 to 103 mainly across central GA. 41 .LONG TERM /Monday Night through Saturday/... 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. The nature of the upper flow could allow for weak short waves to move to the area that would enhance the chances for showers and thunderstorms along with daytime instability. The shower and thunderstorm chances will favor the afternoon and evening but not necessarily end at night. Model guidance is increasing the overall moisture and this will lead to higher rain chances during the coming week. Aiding the shower and thunderstorm chances will be high temperatures in the 90s for much of the area away from the mountains. This will allow for heat indices in the 100 to 105 range for much of the area through late week. Tuesday through Thursday looks to be the hottest with spotty heat indices of 105 to 110 over some locations of central GA. BDL && .AVIATION... 12Z Update...
