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 13, 6:13 PM CST, 30 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 713 PM CDT Tue May 13 2025 ...New AVIATION... .NEAR TERM... (Tonight) Issued at 109 PM CDT Tue May 13 2025 Clouds and shower activity continue to cover much of north AL. This has prevented stronger destabilization and CAPE to develop thus far. However, a rather healthy plume of CAPE over central and northwest MS may begin to spread a bit further northeast later this afternoon, placing the gradient of instability into northwest and central AL. The latest CAMs suggest isolated supercell development early this evening in northeast MS which will drop southeast into northwest and central AL this evening. For now, no major changes will be made to the going forecast for this afternoon or tonight. Low clouds will likely redevelop overnight as well. && .SHORT TERM... (Wednesday through Thursday) Issued at 951 AM CDT Tue May 13 2025 The 5h upper ridge axis will shift east into the OH and TN valleys on Wednesday into Thursday. Southwest flow in low levels will develop with a very warm airmass and EML that will overspread the region. 8h temperatures will reach 16-18C Wednesday and 22-24C by Thursday. A few lingering showers or thunderstorms may remain into Wednesday in our northeast counties. But the EML should cap convection on Thursday. Highs on Wednesday will be in the lower 80s, then in the middle upper 80s on Thursday. && .LONG TERM... (Thursday night through Monday) Issued at 1017 PM CDT Mon May 12 2025 Brief upper ridging will flatten into zonal flow aloft through Saturday as an upper low pivots over the Great Lakes. As this feature shifts over the Great Lakes then over New England, upper ridging (and northwest flow) looks to build over the Mississippi Valley by Monday afternoon. Meanwhile, at the surface, a low coincident with the aforementioned upper low is slated to progress over the Great Lakes on Saturday then the Northeast on Sunday. A trailing cold front associated with this system is expected to approach the Tennessee Valley by Saturday morning. At this time, the front is forecast to stall over the region through late weekend before it possibly moves back north as a warm front early next week. Thus, the reprieve from showers and storms will be short-lived, as unsettled weather returns to the Tennessee Valley for late week through early next week. Daily chances of showers and storms are anticipated, with the highest chances Friday through Friday night ahead of the surface front. Currently, the Storm Prediction Center has a day five 15% area outlooked for severe weather just to our north and west Friday through Friday night. Guidance indicates more than ample shear and instability for severe weather, especially Friday afternoon into the evening. And, although shear decreases somewhat over the weekend, values remain sufficient for additional rounds of potential severe weather through the weekend. The main question will be where the surface front (forcing for storms) sets up. Farther to our north will keep us in the warm sector for a prolonged period and maintain the threat for severe weather. A farther south trajectory would keep us north of the warm sector and could decrease chances of severe storms. Overall, keep an eye on the forecast for late week and have a severe weather plan in place before the storms arrive! && .AVIATION... (00Z TAFS) Issued at 713 PM CDT Tue May 13 2025 VFR to MVFR conditions have persisted this afternoon and are expected to continue through the evening hours. We are monitoring one storm currently approaching KHSV but it has not produced any lightning at this time. Low chances for showers and an isolated thunderstorm will continue through the early overnight hours, but confidence is too low to include that in the TAFs right now. Fog development will be possible overnight, but uncertainty regarding how much cloud cover will exist through the morning hours was too high to include fog in the TAFs at this time as well. Amendments may be needed if fog begins to develop later. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None. TN...None. && NEAR TERM...17 SHORT TERM....17 LONG TERM....26 AVIATION...25
