The areal coverage of the threat is expected to remain too isolated for a watch consideration. DISCUSSION...Ahead of an MCV moving through the Red River Valley, visible satellite shows deepening cumulus and a few thunderstorms from the Concho Valley to Hill Country, with additional cumulus noted along a surface trough from San Antonio to Rock Springs. Latest objective analysis suggests some lingering convective inhibition; however, continued daytime heating will support further air mass destabilization with a gradual increase in thunderstorms expected over the next 1-3 hours. Weak vertical shear will limit the potential for storm organization; however, the presence of a relatively deep, well-mixed boundary layer will be supportive of isolated wind gusts with any more intense pulse storms. ..Mead/Mosier.. 08/27/2026 ...Please see www.spc.noaa.gov for graphic product...
