The upper-level pattern is a bit "messy" with troughing over the Appalachians, a semi-stationary area of low pressure over the ArkLaTex, and an area of high pressure over the central Gulf of Mexico. These features are working together to maintain a feed of tropical moisture over the CWA After an overcast morning, a partly to mostly cloudy sky is expected this afternoon, and high temperatures will largely depend on the degree to which cloud cover scatters out (as well as where and when convection occurs). In general, highs will be in the mid-80s to right around 90, with highs 5-10 degrees cooler in the mountains. Like yesterday, convection looks to get a delayed start due to morning cloud cover. Coverage of showers and storms should peak between ~18z and ~23z, but isolated activity could persist well past 00z. A few strong to marginally severe storms will be possible with gusty to damaging winds, frequent cloud-to-ground lightning, and torrential downpours (the latter could lead to localized nuisance or flash flooding).
Tomorrow (Sunday) morning is expected to start off cloudy as well, with lows in the 70s outside of the cooler mountain terrain. Highs are forecasted to generally be in the 80s. The same general synoptic pattern will be in place, so conditions will be very similar to those today. The HRRR depicts an influx of slightly increased PWAT values (2.0" to 2.2") across much of the CWA, so have gone with chance (~40%) to likely (~70%) PoPs. Mid-level winds are progged to only be 10-15 kts, and with nearly-saturated forecast soundings and tall, skinny CAPE, could have some slow-moving and/or efficient rainfall-producing storms dump heavy rainfall over already-saturated soils. Specifically, WPC has outlined northwest Georgia and a portion of north-central Georgia in a Slight Risk (2 out of 4) for rainfall exceeding flash flood guidance. In addition to localized flash flooding, rises on creeks, streams, and rivers are possible due to runoff. HRRR probability-matched mean QPF indicates that localized rainfall totals of 1.5" to 2.5" are possible across northwest Georgia and as far south as the southern portion of metro Atlanta. In addition to the concern for heavy rainfall and flash flooding, strong to marginally severe storms could produce gusty to damaging winds and frequent cloud-to-ground lightning.

On Sunday night, the ridge pattern over the eastern CONUS will be dampening as a shortwave moves northeastward through the Midwest towards the Great Lakes region. Meanwhile, a low pressure system is anticipated to be centered off the north Atlantic coast.
Moisture return ahead of the shortwave is likely to overcome any relatively drier air remaining over east Georgia between the ridge and on the western side of the low pressure system. Because of this, dewpoints will be in the mid 70s across the majority of the area on Monday. Precipitable water values will also be high, ranging from 1.8 to 2.2 inches. As the shortwave moves north of Georgia overnight into Monday, it will provide forcing for showers and thunderstorms, which will be enhanced by diurnal instability.
Given the combination of these factors, PoPs are forecast to be likely to categorical across the majority of the forecast area on Monday afternoon, with the highest chances in northwest Georgia.
Stronger storms that develop will have the potential to produce heavy rain, which will lead to localized flash flooding concerns, especially given saturated soils from previous rainfall. Broken to overcast cloud coverage on Monday is expected to keep high temperatures limited to the mid to upper 80s.
By Tuesday morning, the shortwave will move out of the region as a broad ridge sets up over the western CONUS. As the ridge slowly moves eastward through the week, much of the Southeast will be underneath a northwesterly flow regime on the "dirty" side of the ridge. While diurnally driven convection is expected to continue each day from Tuesday through the end of the period, the northwesterly flow regime could favor increased shear and chances for organized thunderstorms, and will thus need to be monitored for potential MCS development and associated severe weather threat on these days. Large scale moisture levels are forecast to gradually decrease starting Tuesday into mid-week. At this time, more scattered cloud cover will allow high temperatures to return to the low to mid 90s by the end of the period.

An MVFR cloud deck extending from AHN to the eastern fringes of metro Atlanta will likely bring FEW/SCT clouds ~3000 ft at ATL until ~14z. VFR conditions (albeit low-VFR at times) are generally expected from ~14z through early evening. The potential for TSRA is covered by a PROB30 from 21z to 03z at ATL, as hi-res models suggest a delayed started to convection due to dense mid-/upper- level cloud cover. Winds will be NE to E at 3-8 kts. Looking ahead to tomorrow morning, MVFR cigs appear likely.
//ATL Confidence
12Z Update
Medium confidence on timing/location of afternoon/evening TSRA.
High confidence on all other elements.
