A cluster of strong thunderstorms developed in north central Alabama during the early to mid afternoon hours. One of the thunderstorms produced gusty winds strong enough to lean a power pole over causing a power outage in a section of Huntsville.

The episode as NWS HUN wrote it up.

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 22, 1:01 PM CST, 3 hours 45 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 201 PM CDT Tue Jul 22 2025 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 201 PM CDT Tue Jul 22 2025 A few showers and storms have developed along a weak boundary that is draped from Nashville to Gadsden to Auburn to Dothan. As of 19z, much of this activity has remained fairly benign as subsidence from the mid/upper ridge serves to suppress convection. Much of the more robust showers/storms noted on satellite and radar were displaced to our south and east across east central/southeast Alabama and southwest Georgia. Given the steep low-level lapse rates and SBCAPE values as high as 3000-4000 J/kg, think a few storms could become locally strong -- with gusty winds being the main threat. However, think this will be the exception more than the rule. Otherwise, very hot conditions will persist through the day, with heat index values between 100-109 degrees being common. A Heat Advisory is in effect and have been extended through the overnight period to account for the warm overnight low temperatures that will only bottom out in the mid 70s in most locations. Any convection will quickly wane with the loss of heating with the only other weather impact being some patchy fog develop along sheltered river valleys early Wednesday morning. && .SHORT TERM... (Wednesday through Friday) Issued at 1032 AM CDT Tue Jul 22 2025 The aforementioned subtropical ridge over the Mid South will amplify, with heat concerns continuing again on Wednesday. Thus, we will extend the Heat Advisory through 9 PM Wednesday evening to account for this. Highs in the low to mid 90s will be common again tomorrow, with heat index values in the 100-110 degree range. The center of the ridge will pivot further to the west Thursday and Friday and subsequently highs may be 2-3 degrees lower. However, given dewpoints remaining fairly high, we would anticipate localized heat impacts persisting in a few part of the area (mainly northwest Alabama) where confidence is highest in heat index values reaching/exceeding 105 degrees. Subsidence from the ridge and the lack of an appreciable forcing mechanism will keep diurnal convection largely in check, with PoPs generally around 20-40% each afternoon. && .LONG TERM... (Friday through Monday) Issued at 1042 PM CDT Mon Jul 21 2025 The large scale pattern as we head into Friday and over the weekend will be categorized by high pressure shifting west through the Gulf Coast region as the broader upper ridge begins to become better amplified over the Midwest. Unfortunately, this means there is no end in sight to the heat or daily chances for thunderstorms. The aforementioned high will track west across the FL Panhandle on Saturday and there looks to be some northward extent of the drier airmass accompanying the high. This will bring a very slight relief in humidity and should help keep afternoon heat indices below 105 degrees across much of the area. That being said, highs will still reach the upper 80s/lower 90s and with dewpoints in the low to mid 70s this will still yield heat indices between 97-104 degrees. Temperatures look to heat up at the start of the next work week as the ridge becomes better amplified and H85 temps will once again be on the rise. With the prolonged period of dangerous heat, please continue to practice heat safety, stay hydrated, and check on loved ones and pets that may be especially susceptible to the heat. && .AVIATION... (18Z TAFS) Issued at 1206 PM CDT Tue Jul 22 2025 VFR conditions will be the most predominant flight category at each terminal through the period, with light winds and a mostly clear sky. Low chances for a SHRA/TSRA will exist this afternoon, but confidence is too low to mention in the TAF at this time. && .HUN WATCHES/WARNINGS/ADVISORIES...
