The episode as NWS FFC wrote it up.

Area Forecast Discussion National Weather Service Peachtree City GA 131 PM EDT Tue Aug 15 2023 ...New 18Z Aviation Discussion... .SHORT TERM... (Today through Wednesday) Issued at 405 AM EDT Tue Aug 15 2023 Finally. It's here. The cold front we've all been waiting for. A line of showers and thunderstorms has been working through southern TN during the overnight hour along the upper level trough out ahead of the surface trough set to move in this afternoon. We should see high temps this afternoon limited to the upper 80s and low 90s north of I-85. The front will push through the rest of the CWA overnight and into tomorrow. Precip associated with the front will be most prevalent late this afternoon and during the overnight hours. It will be focused mostly across the southern part of the CWA where QPF totals are hovering around an inch; although isolated higher totals are possible especially with training storm potential overnight. Widespread severe weather is not expected, but a few storms could be strong with gusty winds and frequent lightning especially during the peak heating hours of the afternoon. Tomorrow the front pushes the rest of the way through the CWA and we're left with all the benefits. "Cool" dry air and some lingering showers across the far SE part of the CWA will be the afternoon's story. Highs will be limited to the upper 80s and low 90s across the area. Get out an enjoy the day while you can, because this trend doesn't look like it will survive in the Long Term Forecast. Vaughn && .LONG TERM... (Wednesday night through Monday) Issued at 405 AM EDT Tue Aug 15 2023 As the extended period begins, an amplified upper level pattern will be in place across the majority of the CONUS, with a trough extending from the northern Great Lakes towards the central Gulf Coast, and a persistent ridge over the western half of the country. A surface low associated with the trough will extend a cold front southward, which will be in the process of pushing into central Georgia on Tuesday night. As the front continues to move southward through the area through the overnight hours, scattered to numerous showers and thunderstorms will be ongoing ahead of the frontal boundary. Some storms ahead of the front could become strong, capable of producing gusty winds and frequent lightning. Portions of east-central Georgia are anticipated to see rainfall amounts of 1- 1.5 inches through the overnight hours, with locally higher amounts associated with stronger storms that occur. Significantly drier air will meanwhile build in behind the front, dropping dewpoints into the upper 50s and low 60s and precipitable water values to between 0.6-0.8 inches. Temperatures will also be noticeably cooler on Wednesday morning, with lows dropping into the low to mid 60s in north Georgia (and even some 50s in the higher elevations). The surface front is expected to stall in southeast Georgia on Wednesday morning and linger through much of the remainder of the work week. With dry air and ample sunshine, high temperatures will be in the mid to upper 80s in north Georgia and in the upper 80s to low 90s in central Georgia on Wednesday. However, with lower dewpoints, we are not expected to approach Heat Advisory thresholds. Precipitation chances Wednesday through Friday will be minimal within the dry airmass to the north of the frontal boundary. However, the front itself will provide a focus for scattered, diurnally driven convection each afternoon from Wednesday through Friday, which will keep slight chance to low-end chance PoPs in east- central Georgia each day. Temperatures will undergo a gradual warming trend through the end of the week, with highs increasing by a couple of degrees each day. On Friday, the aforementioned trough over the eastern CONUS will begin to lift away as upper level ridging begins to build into the Southern Plains from the west. This will cut off the persistent northwesterly upper level flow regime, allowing for the development of a more typical summertime Bermuda ridge to develop. As a result, low level moisture and PoPs will begin to increase once again this weekend. King && .AVIATION... (18Z TAFS) Issued at 130 PM EDT Tue Aug 15 2023 VFR areawide with TEMPOs moved up to account for earlier than expected convection across North GA (18Z-22Z). Further amend might be needed with rear development. Winds may become gusty, particularly around thunderstorms. W-WSW winds will continue to turn to NW through the afternoon hours behind front. VSBYs at MCN may drop tonight as front stalls to the SE. //ATL Confidence...18Z Update... Medium confidence rear PoPs and motion of cold front. High confidence all other elements.
