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 Jul 7, 4:24 AM CST, 3 hours 36 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 524 AM CDT Mon Jul 7 2025 ...New AVIATION... .NEAR TERM... (Today) Issued at 227 AM CDT Mon Jul 7 2025 A 5h/8h trough axis and associated cold front from the eastern Corn Belt into the Ozarks and Red River Valley will slowly slide east into the lower OH and mid MS Valley today. The trough and front will produce fairly widespread showers and thunderstorm today well to our northwest. A weaker sheared vorticity axis located further southeast from middle TN through northwest AL into MS will serve as a potential trigger for isolated to scattered thunderstorm development this afternoon, mainly across northwest AL into middle TN. Afternoon highs will reach 90-95 in valley areas (upper 80s atop the higher plateau areas). The heating will result in steep low level lapse rates and promote brief gusty winds of 30 to 40 mph in the stronger thunderstorms. && .SHORT TERM... (Tonight through Wednesday) Issued at 1001 PM CDT Sun Jul 6 2025 With a loss of daytime heating and resultant instability, convection that forms should dissipate as we go into Monday evening. With a wetter ground from somewhat better coverage of rainfall, fog formation appears more probable Mon night with light winds and mostly clear skies forecast. Weak upper ridging that has been helping control the area's sensible weather the past few days should continue to weaken and shift to over the western Atlantic basin over Bermuda, and another upper ridge over the Desert SW and northern Mexico. Upper level troughing will become more pronounced over the eastern Lower-48, as an upper level low moves from Alberta/Saskatchewan to the Great Lakes region towards the middle of the week. Lower heights produced by an amplifying trough will produce cooler upper levels; hence higher overall instability, and greater chances of showers and thunderstorms Tuesday and Wednesday. Rain chances on Tue should rise to around 70 percent and 80 percent Wed. Precipitable water amounts in the regional atmosphere in the ~1.5 to 1.7" range Tue will increase to ~1.7 to 2" on Wed. This could result in locally heavy rainfall becoming an issue. Some storms in these high moisture laden environments can become prolific lightning producers. Before showers become more of an issue, one very warm to hot day is forecast Tue with highs rising into the lower 90s. Heat indices could rise into the upper 90s to 105 degrees Tue afternoon thanks to higher relative humidity values and very warm temps. If areal coverage of the higher end of this heat increases, we cannot rule out a future Heat Advisory. It should be a bit "cooler" Wed with highs around 90. Lows Mon-Tue night should range in the lower 70s. && .LONG TERM... (Wednesday night through Sunday) Issued at 1001 PM CDT Sun Jul 6 2025 Unsettled weather is expected into the upcoming weekend, as a moisture laden environment persists, and strong July heating makes for higher daytime instabilities and brings high chances for showers and thunderstorms. Average precipitable water amounts into the ~2 inches range will bring a risk for more heavy rainfall. It is too far out to determine which area(s) could be impacted by heavy rainfall at this time. But there is a reasonable possibility that area creeks, streams, rivers, and lakes could experience rises in water levels late this week and in during the weekend. Please stay tuned to future forecasts on this potential. And as noted above, storms in these environments can be electrically active, with lightning posing a danger. With more clouds and higher rain chances, high temperatures should be a tad milder in the mid 80s to around 90 Thursday and Friday. The NBM further out has highs a bit warmer from the upper 80s to lower 90s, matching with somewhat lower rain chances. Overnight lows in the long term should range in the upper 60s to lower 70s. && .AVIATION... (12Z TAFS) Issued at 524 AM CDT Mon Jul 7 2025 There is a low chance of SHRA or TSRA after 18Z, but confidence remains too low to include in either KMSL or KHSV TAF at this time. Otherwise, prevailing VFR conditions are expected through the period. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None. TN...None. && NEAR TERM...17 SHORT TERM....RSB LONG TERM....RSB AVIATION...17

1 heat. Local standard time, as filed.
A 36 year old male collapsed on a job site on Smith Lake at the Lions Club Landing area. They were transported to the hospital and died of Hyperthermia coincident with another medical condition.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
