The episode as NWS FFC wrote it up.
Strong diurnal heating and ample low-level moisture resulted in a moderately unstable atmosphere, producing isolated severe thunderstorms each afternoon and evening.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before the first event at Jun 28, 6:41 PM EST, 44 minutes earlier.
Area Forecast Discussion National Weather Service Peachtree City GA 741 PM EDT Sun Jun 28 2020 ...00Z Aviation Forecast Discussion... .PREV DISCUSSION... /Issued 312 PM EDT Sun Jun 28 2020/ ..Afternoon Area Forecast Discussion for Sunday, June 28... SHORT TERM /Tonight through Monday Night/... While some initial isolated convection has triggered in parts of north GA, the main focus continues to be on potential for more organized quasi-linear convective cluster this afternoon into evening given ridge rider setup. Current wave of storms propagating across TN has some CAM solution support to make it's way into portions of north GA. The instability axis is in a favorable orientation to this wave for a continued track into the northern CWA as well. The Day 1 SPC Outlook update did also expand the Marginal Risk into the far north and east accordingly to this potential. Made some increased pop adjustments to go a bit later in the north and east. Some enhanced moisture and possible weak upper impulse influence keeps some lingering pops across far north GA overnight and then the upper ridge is progged to dampen some for Monday afternoon so again have some chance pops in the northern majority and slight farther south for mostly diurnally driven showers and storms. Temps look to increase to above climo for Monday with most areas above 90 and with eastern central GA progged to get into the mid 90s, resultant heat indices could make it in the low 100s. For now look a few degrees below heat advisory criteria so not planning on issuing but will need to monitor if future updates trend warmer. Baker LONG TERM /Tuesday through Sunday/... A cut off low will be spinning to the northeast of the area on Tuesday as part of a larger Omega block over the CONUS. Viewing the dynamic tropopause within the models reveals several smaller cyclonic features that are trapped under the larger ridge within the Omega block which are providing some lift due to CVA as they move about. Moving forward, the cut-off low should absorb into the flow but may leave behind a separate cut-off which may merge with one of the cyclonic features along the dynamic tropopause just to the west of our region. The net result of all this will be a very wet forecast through the long term. PWAT values are forecast to remain above 1.5 through the entirety of the long term, and with an impulse to the west of the area, plenty of lift and moisture should continue to overspread the CWA and provide plenty of chances for afternoon and evening thunderstorms. Generally went with the blend, as exact details of how these afternoons and evenings play out will be best left to mesoscale models. One benefit of the cut-off and consistent cloud cover and associated precipitation will be to reduce afternoon high temperatures somewhat. While highs will be in the upper 80s all the way to upper 90s in central GA on Tuesday, afternoon high are expected to come down a few degrees across the state moving forward. The humidity will not be leaving any time soon, however, as dewpoints are expected to remain in the 70s throughout the forecast period. Lusk && .AVIATION... 00Z Update... VFR conditions are largely expected to prevail through the forecast period, though brief MVFR is possible at CSG after 11-13z Monday. While shra/tsra coverage this evening is limited, highest potential for impacts through 02z is at CSG before coverage is expected to diminish further. Additional scattered shra/tsra is possible Monday afternoon, primarily at ATL/AHN area sites. Winds will remain westerly 3-6kts overnight increasing to around 10 kts Monday with gusts 15-18kts possible. //ATL Confidence...00Z Update...
