The episode as NWS HUN wrote it up.
A combination of miniature supercells and segments of thunderstorms produced gusty winds and heavy rainfall. Excessive rainfall resulted in flash flooding in the Scottsboro area. Also, thunderstorm winds knocked down trees and power lines on the southeast side of Scottsboro.
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 Sep 24, 12:49 PM CST, 3 hours 30 minutes earlier.
Area Forecast Discussion National Weather Service Huntsville AL 149 PM CDT Wed Sep 24 2025 ...New NEAR TERM... .NEAR TERM... (Tonight) Issued at 149 PM CDT Wed Sep 24 2025 New convective clusters have develops in northwest into west central AL. This activity will be at the nose of the plume of 2000-3000 j/kg SB CAPE values in western AL. Effective bulk shear of 25-35kt was noted in this area as well. Thus, during the next few hours, the greatest risk of strong to severe thunderstorms exist. The greatest risk may also be south of the TN River within the higher plume of instability. Further north, instability has been limited by multi-layer clouds and precipitation. With PWs of 2-2.2 inches, intense rainfall rates in combination with echo training on already saturated or near saturated soils could lead to excessive rainfall. As stated in the morning discussion, the MCS over AR/LA will be advancing east-southeast and will affect areas to our southwest. Additional thunderstorms and showers may develop further north of this activity this evening in advanced of the upper trough. Most of this activity is progged to shift east this evening, exiting our eastern counties by 06-08Z. However, it is unclear if this activity will remain a severe weather risk. Previous Discussion... .NEAR TERM... (Rest of Today and Tonight) Issued at 1002 AM CDT Wed Sep 24 2025 Radar showed an MCV has pushed east through the area and is now north of Chattanooga. Clusters of showers and a couple of embedded thunderstorms have filled in behind this with heavy downpours within a plume of 2-2.2 inch PW and southwesterly 850 mb winds of ~20kt. Rain rates of 1-2 inches per hour have occurred with some of this activity. CAMS indicate that additional clusters of showers and thunderstorms will develop this afternoon, however, given the expansive cloud shield from the MCS over the AR/MS/LA area, instability may be inhibited somewhat. And with weak mid level lapse rates, the risk of severe weather remains fairly low at this time. As the MCS over AR/LA/MS drops southeast this evening, additional showers and a few thunderstorms will develop in advance of the upper trough dropping into the lower MO Valley through the Red River Valley. However, depleted instability will limit the risk of severe storms this evening. Thus, the SPC marginal risk looks good at this time. Locally excessive rainfall may be more of a risk later today into this evening given the high PWs and ongoing rainfall producing saturated soils in some locations. && && .SHORT TERM... (Thursday through Friday) Issued at 1002 AM CDT Wed Sep 24 2025 On Thursday into Friday, the slow moving upper trough will shift into KY through west TN/north MS where a more distinct vorticity center develops. The associated cold front will also be a slow mover, not exiting our southeast counties until sometime on Friday. Thus, light to moderate showers and perhaps a thunderstorm or two are forecast Thursday (medium to high chance), lingering into Friday (very low to low chance). High temperatures will be held in the upper 70s to lower 80s in valley areas, and even cooler atop the higher Cumberland Plateau locations. Lows will be in the upper 50s to lower 60s. && .LONG TERM... (Friday night through Tuesday) Issued at 1051 PM CDT Tue Sep 23 2025 The forecast for much of the long term looks dry thanks to high pressure over the mid MS River valley. Highs will top out near the low to mid 80s each afternoon with lows in the upper 50s/lower 60s. Low rain and thunderstorm chances look to creep back in early next week as the aforementioned upper low begins to shift back west over the region resulting in an increase in moisture and slightly warmer temperatures. && .AVIATION... (18Z TAFS) Issued at 1210 PM CDT Wed Sep 24 2025 Clusters of SHRA and TSRA, some with +RA will expand in coverage through 00Z. Coverage should decrease after 02-04Z. Then, low ceilings are forecast to develop by 06-08Z below 010agl (IFR) with scattered -SHRA and isolated TS still possible. Ceilings will slowly lift to 010-020agl (MVFR) by ~17Z. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...None. TN...None. && NEAR TERM...17 SHORT TERM....17 LONG TERM....25 AVIATION...17
