The episode as NWS HUN wrote it up.
A line of thunderstorms moved east across north Alabama and southern middle Tennessee during the late morning and early afternoon hours. The storms picked up intensity along the I-65 corridor and points east. Three tornado tracks were surveyed (2 EF-1 and 1 EF-0) and several wind damage reports were received.
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 Huntsville, AL wrote its last area forecast discussion before the first event at May 9, 9:04 AM CST, 2 hours 24 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 1004 AM CDT Thu May 9 2019 .NEAR TERM...(Rest of Today) Issued at 1004 AM CDT Thu May 9 2019 A broad area of showers and thunderstorms continues to progress east into the region this morning ahead of a surface cold front to the northwest of the area. Much of the deeper convective activity this morning has been driven by remnant outflows and a cold pool that pushed east with time toward the AL/MS border. The thermodynamic environment across North Alabama is quite meager to say the least, with only 250-500 J/Kg of SBCAPE to work with (at most) across our region as of 15z. It's possible that further destabilization may occur later in the day ahead of this convection, though heating will be limited given the dense cloud cover. About 20-30 kts of 0-1 km shear is in place across the area, but shear is unidirectional and fairly uniform with height, meaning only 30-40 kts of bulk shear. Needless to say, this will allow for some storm organization, but the limit duration and intensity of this activity. This can already be seen in the latest satellite and radar trends, which have indicated a gradual weakening trend with the deeper convection has it's moved into North Alabama. Thus, think the main impact (as seen by PWATs around 1.5-1.6 inches) will be moderate to heavy downpours and lightning. A few locally strong storms are possible, but with a very moist atmospheric profile, it will be harder to mix down the stronger convective wind gusts. Still, given the aforementioned low-level shear, can't rule out a few stronger wind gusts through this afternoon as these clusters of showers and storms move through the region. This activity should move through Northwest Alabama this morning, into the I-65 corridor and HSV Metro by 17-18z, and Northeast Alabama by 20-21z. Some scattered light rain showers will linger into the early evening, but the threat for any stronger convection in our area should wane by the mid/late afternoon. .SHORT TERM...(Tonight through Saturday night) Issued at 430 AM CDT Thu May 9 2019 Thunderstorm coverage and intensity should drop off quickly during the early evening hours, as the front pushes into Georgia and central Alabama. However, scattered showers and isolated thunderstorms may linger through the overnight hours. Another warm and muggy night is in store Thursday night with lows only dropping into the mid to upper 60s again. Models disagree on exactly where the the frontal boundary is overnight on Thursday into Friday morning. However, it likely will be somewhere between central Alabama and the Tennessee River based on most guidance. Therefore, leaving scattered showers and thunderstorms in the forecast Friday morning. Models do seem to be in better agreement that this front will move back to the north Friday afternoon into northern Alabama. This should increase rainfall and thunderstorm chances significantly. Will need to monitor this period into the evening hours on Friday for stronger thunderstorm development. For now though, activity in the morning and early afternoon may keep instability a bit too low for this to occur. Either way, will need to start keeping an even closer eye on isolated flash flooding potential then. The overall weather pattern changes little through Saturday night, as the front stalls near the area. In addition, several additional pieces of upper level energy move along this front. Ample forcing will be present at times along with deep atmospheric moisture for the continued development of additional showers and thunderstorm activity. Some of these storms could be strong, but the bigger threat should be heavy rainfall and potential flooding. .LONG TERM...(Sunday through Wednesday) Issued at 430 AM CDT Thu May 9 2019 An unsettled pattern will be on-going as we go into a new week. A frontal boundary should be draped in a SW-NE manner across this region on Sunday morning. The big question is exactly where? Leaning toward an ECMWF/Canadian/GFS-FV3 and GFS-ensemble view (has the front located just NW of the region), a southerly flow bringing moisture from the Gulf will continue to produce widespread showers/thunderstorms across the area for Sun morning and afternoon. Forecast soundings from the GFS show precipitable water amounts in the 1.6" range Sun AM, with those values decreasing into the afternoon. Total rainfall amounts across the Tennessee Valley by Sun evening should range from 2-4 inches. A long duration of this precip should not cause serious short-term hydrological concerns (flash flooding). But longer term river rises do look probable for the first half of next week. Surface low pressure situated across the TN/KY region Sun morning should head to the NE during the course of the next day, reaching the coastal Mid Atlantic Monday morning. A cold front extending from this low by this time should be south of the Tennessee Valley. This will result in rain chances diminishing from NW to SE during the course of Sun, with the last of the showers ending over NE Alabama in the evening. High pressure from the Canadian/United States Rockies will build to the SE, and bring a cooler conditions for the first half of next week (especially compared to temperatures this week). Clouds and showers will make for highs only in the low/mid 70s on Sunday. Even with the sun returning to start another workweek, high temperatures on Mon/Tue under cold air advection will only warm into the mid 70s. We should see high temps rise closer to seasonable norms, into the upper 70s on Wednesday. Normal highs by next Wed are around 81. With cool days, night time conditions early next week will be on the chilly side. Lows will average in the low/mid 50s in the Sun-Tue night time frame. Temperatures before daybreak Tuesday will chill into the upper 40s in our normally colder spots. Normal lows Tue night are around 59. && .AVIATION...(For the 12Z TAFS through 12Z Friday morning) Issued at 639 AM CDT Thu May 9 2019 A few -SHRA may affect either KHSV or KMSL through 14Z, but believe the majority of the more persistent rainfall should remain to the west/northwest of the terminals through then. However, after 14Z more persistent rainfall and lower VFR CIGS are expected. A tempo group was included for both terminals (KMSL between 14Z and 16Z/KHSV between 15Z and 18Z) with +TSRA and MVFR CIGS and VSBYS. These conditions may be lower than indicated and the window a bit later, especially at KHSV. Then kept predominant MVFR CIGS and after 18Z through 21Z at KHSV and after 16Z through 18Z at KMSL. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.

Isolated to scattered thunderstorms should increase in coverage and intensity ahead of an approaching cold front this morning into the afternoon hours. A few storms could be strong to severe, especially west of the I-65 corridor. Damaging winds up to 60 mph and locally heavy rainfall are the main threats with this activity. This thunderstorm activity should weaken and become scattered by the early evening hours, as a front stalls near the area. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... As unsettled pattern will continue Friday through Sunday, as the front moves northward towards the Tennessee Valley and stalls near northern Alabama/southern middle Tennessee. Scattered to more numerous showers and thunderstorms are expected. Some storms could be strong producing gusty winds and localized flooding. A return to drier weather is expected early next week. .SPOTTER INFORMATION STATEMENT... Limited activation of storm spotters and emergency management personnel is possible this afternoon. 20
