Valid 112038Z - 112245Z The severe weather threat for Severe Thunderstorm Watch 482 continues. SUMMARY...Strong to severe gusts remain possible through this evening across the watch area, and may eventually occur east of the watch into northern Alabama and southern Middle Tennessee. DISCUSSION...Storms have developed along the front this afternoon, extending across northern AR and into western TN. Strong wind gusts have been reported, with a peak wind of 47 kt measured at KMKL at 2009Z. The air mass remains strongly unstable across the entire watch area, and westerly winds have also warmed temperatures above 90 F into Middle TN and northern AL. As such, corridors of damaging gusts appear likely as stronger sections of the line bow toward the southeast. Additional activity has developed near the eastern edge of the watch into southern parts of Middle TN where the air mass has recovered. Depending on storm trends, a new watch may be considered east/downstream of WW482 later today. ..Jewell.. 07/11/2026 ...Please see www.spc.noaa.gov for graphic product...
