The episode as NWS BMX wrote it up.
An upper low positioned over Mississippi brought widespread rain and thunderstorms across the area, generally from south to north. A couple instances of training thunderstorms brought several inches of rain to the Tuscaloosa and Selma areas, resulting in areas of street flooding. One thunderstorm just east of Selma briefly produced quarter-size hail in Burnsville.

NWS Birmingham, AL wrote its last area forecast discussion before the first event at May 10, 1:09 PM CST, 1 hour 21 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Birmingham AL 209 PM CDT Sat May 10 2025 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 200 PM CDT SAT MAY 10 2025 - Localized flash flooding may become a more significant threat this afternoon through Sunday evening due to torrential rainfall rates and storms moving over already saturated ground conditions. - There is a marginal (level 1 of 5) risk for severe storms on Sunday afternoon into the evening. Damaging winds and large hail are the primary hazards. && .SHORT TERM... (This evening through Sunday) Issued at 200 PM CDT SAT MAY 10 2025 A dynamic weather setup is currently taking place over the Deep South with many different features ongoing both in the synoptic and mesoscale levels. First synoptically, a 500mb closed low is now centered over the ArkLaMiss with a deep southerly fetch of moisture currently being transported northward within a 25 to 30 knot 700-500mb jet. At the surface, a low pressure area is currently centered over extreme southwestern Alabama, with a warm front extending eastward through southern Georgia. Along and south of the front, a very tropical airmass exists with dewpoints observed in the upper 60s to lower 70s. As clouds continue to break up across southern Alabama, additional destabilization of the environment is expected to occur with afternoon heating. A long-lived supercell with a confirmed tornado occurred just before midday very close to where the warm front was located in Holmes County, FL and Geneva County, AL. Farther to the north, most of the CWA is in a more stable environment thanks to a potent CAD wedge that is advecting drier and cooler air from the east over Alabama and much of Georgia. Gradient winds have really picked up from the wedge this afternoon, with gusts approaching 30mph in some locations across eastern Alabama. As a dry slot works northward on the east side of the surface low through this afternoon, we can expect the overcast conditions to become more broken with additional sunshine across the southern half of the CWA. With additional instability, some strong storms are certainly possible with gusty winds and hail as the warm front starts to lift northward. We'll keep an eye on those through the afternoon, as well as watching for the potential for flooding, as current rainfall rates are very tropical in nature due to the very efficient moisture transport north and westward. Training storms moving southeast to northwest due to the very slow movement of the nearby surface low could certainly lead to localized flooding, especially in urban and low-lying areas through this evening. Overall coverage of rain and storms is expected to diminish overnight as the current surface low is absorbed by the larger mid-level closed low and it becomes a vertically-stacked system. Additional bands of showers and storms are expected to develop areawide during the day on Sunday, beginning first along and east of I-65 and then transitioning westward by Sunday afternoon. A heavy band of showers and storms is progged by several of the CAMs to develop across southwestern Alabama and lift northward through Sunday evening. Flooding will need to be closely monitored along with the potential for a few strong to severe storms with a wind and hail threat. Flooding may become the overall primary threat as torrential rains fall over already saturated ground conditions. A heavy band of showers and storms is progged by several of the CAMs to develop across southwestern Alabama and lift northward through Sunday evening that could bring the best chance for observing flash flooding. 56/GDG && .LONG TERM... (Sunday night through next Friday) Issued at 200 PM CDT SAT MAY 10 2025 No major changes were made to the long-term forecast this afternoon, and previous discussion remains valid below. As the upper level system and upper trough lifts out to the north and east by Wednesday, ridging will begin to our south and west which will bring drier and much warmer conditions by Thursday and Friday. 56/GDG Previous long-term discussion: (Sunday night through next Friday) Issued at 245 AM CDT SAT MAY 10 2025 Sunday night through Tuesday. A closed upper low will be positioned over much of North-Central Louisiana Sunday night while low amplitude ridging will be positioned over Northern Mexico and New Mexico and mid-level shortwave ridging will be over much of the Mid Atlantic and Ohio River Valley regions. The mid-level pattern will begin to amplify during the day on Monday as deep longwave troughing moves east over the Pacific Northwest, resulting in the downstream ridging amplifying over the Desert Southwest and Southern Plains. The upper low will begin migrating northeastward, becoming centered over the Mid-South Region Monday night before becoming centered over the Southwest Ohio River Valley Region later in the day on Tuesday. A surface low will develop across Central Mississippi Sunday night and will become occluded due to the presence of the upper low nearby aloft. An occluded front looks to extend southeast to a triple point across Interior Southwest Alabama during this time with a narrow warm sector that will gradually lift northward from the Immediate Central Gulf Coast into our South-Central Counties from late Sunday into the day on Monday. The surface low will move northeast into Western Tennessee by Tuesday morning while the triple point becomes positioned well to our east across Georgia and South Carolina while relatively weak surface high pressure moves in from the southwest. Mostly cloudy skies with numerous to likely (65-95%) chances for showers and thunderstorms will persist Sunday night with greatest potential across the northeast portion of the forecast area. Expect likely (80-95%) chances for showers and thunderstorms Monday under cloudy skies areawide with the best potential for activity across the northeast portion of the forecast area. Shower and thunderstorm activity will gradually become more confined to the northeast third of the area Monday night where numerous to likely (70-90%) chances for showers and storms will exist with scattered (40-70%) chances across the remainder of the forecast area except for isolated (20- 40%) across the southwest third of the area. Chances for numerous (60-80%) showers and storms will exist across the northeast quarter of the area Tuesday while scattered (35-60%) chances will exist elsewhere with lowest chances southwest. Isolated (15-25%) chances for lingering showers and a few storms will remain possible Tuesday night across the northeast third of the area with lower chances toward the southwest. Lows Sunday night and Monday night will range from the upper 50s north and northeast to readings in the lower 60s south and southwest while highs Monday and Tuesday will range from the lower 70s far north and in the higher elevations east to readings in the around 80 far south and far southwest. Wednesday through Friday. The upper low will gradually fill as it continues migrating northeast across the Central Ohio River Valley Region while remnant troughing will gradually move east of the state, becoming centered over East Tennessee and North-Central Georgia through the day Wednesday. Broad Ridging will build over the Southern Plains ahead of the deep longwave trough moving southeast over much of the Pacific Northwest during this time. Remnant troughing will become centered over the Mid-Atlantic Region by Thursday while longwave ridging will become centered over the Lower and Mid-Mississippi River Valley Region. The longwave ridge axis will move east over the area on Friday as an upper low develops over the Northern Plains and moves into Southern Canada with residual troughing lingering over the Four Corners States. Relatively weak surface high pressure will become centered to the south of the forecast area during the day Wednesday as the forecast area becomes positioned between the lingering occluded low across Central Virginia and deepening surface low pressure across the Central Plains. Surface high pressure will become centered to the southeast of the area Thursday and Friday while a strong storm system develops across the Northern Plains and Souther Canada with the associated cold front advancing eastward toward the Great Lakes and Mid-South Regions. Skies will become partly cloudy areawide on Wednesday with isolated (10-20%) chances for some shower and thunderstorm activity across the northeast third of the forecast area on Wednesday while dry conditions are expected elsewhere. Fair skies and dry conditions will return areawide by Wednesday evening and persist through the day on Friday despite some increasing clouds from the northwest later in the day. A warming trend will ensue with the return of drier conditions Wednesday through Friday. Lows will range from the upper 50s northeast to the low 60s southwest Wednesday morning followed by lows areawide in the 60s both Thursday and Friday mornings. Highs will range from the low 80s far east to the upper 80s far south Wednesday then increasing into the mid and upper 80s Thursday followed by readings from the upper 80s north and east to the lower 90s elsewhere on Friday. 05 && .AVIATION... (18Z TAFS) Issued at 1239 PM CDT SAT MAY 10 2025 Widespread SHRA with reduced visibilities and IFR stratus continues to cause significant aviation issues across most of the terminals, with some improvement in the near term at MGM. Additional improvement is expected for all remaining terminals through 21z as lower clouds begin to erode from south to north and showers become more scattered in nature. We'll need to keep an eye on the potential for TSRA development near MGM through 00z, but for now have gone with VCSH and a PROB30 for TSRA. Amendments will likely be needed as storm coverage increases near the MGM vicinity. Gusty winds from the east are also presenting aviation challenges, prevailing around 15 knots with gusts between 25 and 30 knots. Winds are expected to diminish during the overnight hours tonight. IFR stratus development will likely occur once again tonight areawide, with lingering SHRA and occasional reductions in visibility. IFR stratus is expected to linger through 15z Sunday morning. 56/GDG && .FIRE WEATHER... Rainy conditions will persist through Monday. Rain chances decrease in the southwest by Monday night but remain elevated in northeastern counties through Tuesday. Min RH values will remain above 50 percent this afternoon and above 75 percent over the weekend. By Monday, RH values could fall back to near 50 percent across southern or southwestern areas. 20 ft winds will increase tomorrow and Sunday, generally easterly up to 10 mph. By Monday, winds will shift southerly up to 8 mph. && .PRELIMINARY POINT TEMPS/POPS...
