The episode as NWS CHS wrote it up.
Rounds of heavy rainfall producing thunderstorms tracked across portions of interior southeast Georgia, producing a few instances of flash flooding. The heavy rain developed near a stationary boundary associated with a surface low situated across the lower Mississippi Valley. Some of the heaviest rain fell across Candler and Tattnall counties where automated rain gages and CoCoRaHS observers reported a range of 5-8 inches of rain. Specific observed amounts include 8.72 inches at the Metter coop site, 7.94 inches at the Reidsville USGS gage, and 7.79 inches at the RAWS site near Metter.

NWS Charleston, SC wrote its last area forecast discussion before the first event at May 11, 12:53 PM EST, 1 hour 7 minutes earlier.
Area Forecast Discussion National Weather Service Charleston SC 153 PM EDT Sun May 11 2025 .SYNOPSIS... A front will remain stalled near the area through early this week. Weak low pressure will slowly move through Monday into Tuesday, followed by high pressure. && .NEAR TERM /THROUGH TONIGHT/... Radar continues to be fairly active, especially over interior Georgia where a band of showers and thunderstorms set-up and produced a widespread 3-5 inches of rain with an automated site in Tattnall that even reported closed to 10 inches. Additional rounds of showers and thunderstorms are expected over the entire area through the remainder of the day. By mid to late afternoon, a warm front is expected to lift across SE GA. The environment south of the warm front will feature SBCAPE of 1500-2000 J/kg and SRH around 100 m2/s2. Strong to severe thunderstorms are possible along and south of the warm front. SPC has highlighted the area with a marginal risk for severe weather. However, machine learning guidance indicates some risk of a tornado and severe wind gusts. High temperatures are forecast to peak in the mid to upper 70s. Showers and thunderstorms should increase from south to north this evening. Categorical PoPs will remain through the night as the sfc low over the Deep South begins to track east. Some areas may receive an additional 1 to 1.5 inches tonight. Low temperatures are forecast to range in the mid to upper 60s. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... A mid-level closed low will remain over the southeastern states on Monday before progressing northeastward towards the Mid-Atlantic states Tuesday into Wednesday. At the surface a front will be stalled in the vicinity of the forecast area, with low pressure traversing the frontal boundary from the Gulf Coast northeastward towards the local forecast area. Monday into Monday night will likely be the most active of the period, with widespread showers and thunderstorms ongoing at sunrise and several waves of additional showers and storms through the day and into the overnight. There is the potential for heavy rainfall on Monday, with the WPC continuing to highlight the region in a Slight Risk of Excessive Rainfall. Additional rainfall totals on Monday are forecast to be around 1 to 2 inches, with the potential for locally higher amounts with thunderstorms. Given the ongoing drought flooding is not a major concern, however minor flooding of low-lying, poor drainage, and urban areas is possible. Additionally, a strong to marginally severe thunderstorm will also be possible with some instability present. High temperatures Monday will be below normal, given precipitation and cloud cover, with low to mid 70s and some upper 70s along the Altamaha River in GA in the forecast. With expected cloud cover, overnight lows Monday night will remain mild, only dropping into the 60s. Temperatures on Tuesday and Wednesday will return to near normal as precipitation wanes and sunshine returns, with highs reaching into the low to mid 80s. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... The mid level closed low will open and lift off towards New England on Wednesday night. Thereafter ridging is forecast to build into the region aloft while high pressure builds at the surface. Isolated showers and thunderstorms are possible Thursday afternoon, with a dry forecast maintained into the weekend. The highlight of the period will be the building temperatures. By Friday high temperatures are forecast to reach into the 90s across the entire forecast area, with heat indices possibly reaching triple digits. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... Periods of showers and thunderstorms are likely through the rest of the TAF period, resulting in reductions in ceilings and visibilities. Even outside of convection, sub-VFR ceilings are expected for most, if not all, of the TAF period. Winds will increase on Monday. Extended Aviation Outlook: MVFR or lower cigs and/or vsbys possible through Tuesday as a front remains stalled nearby and several rounds of showers/tstms move through. && .MARINE... Thunderstorms will remain common across the marine zones into tonight with locally strong wind gusts and perhaps an isolated waterspout possible. The pattern will support southeast winds between 10 to 15 kts. Seas should remain between 2 to 4 ft today, increase to 3 to 5 ft tonight. Monday through Thursday: A stalled front will linger in the vicinity of the coastal waters into the middle of the week. Southeasterly flow will prevail on Monday with 15-20 knots and gusts to around 23 knots. Seas will build to 4 to 5 ft, with some 6 ft possible across the 20 to 60 nm offshore GA waters and the nearshore Charleston County waters Monday and into Tuesday. Small Craft Advisories may be required. Conditions will improve on Wednesday and into the end of the week with seas 2 to 3 ft and southerly winds around 10 knots. Rip Currents, the combination of a lingering longshore current and 2 to 3 breakers may produce rip currents along the SC/GA coast today. A moderate risk will be posted until 8 PM this evening. Rip currents risk will remain moderate on Monday. && .CLIMATE... Record Precipitation: May 11: KCHS: 1.93/1952 *as of 145 PM rainfall 3.24 inches KCXM: 1.57/1899 *as of 1230 PM rainfall 3.76 inches && .CHS WATCHES/WARNINGS/ADVISORIES... GA...None. SC...None.
