Subj : DAY1SVR: Day 1 Convective To : All From : Mike Powell Date : Tue Aug 26 2025 09:42:39 ACUS01 KWNS 261249 SWODY1 SPC AC 261248 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0748 AM CDT Tue Aug 26 2025 Valid 261300Z - 271200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Organized severe storms are not expected across the continental U.S. today. ....Synopsis... An expansive upper-level trough will persist across the eastern CONUS today, where a cool, dry airmass and high pressure will be prevalent and limit thunderstorm potential aside from Florida. Monsoon-related scattered thunderstorms will be common across much of the non-coastal West. ....Southern Arizona/Lower Colorado River Valley... A northward-moving mid-level impulse/MCV will spread from the Lower Colorado River Valley/northern Arizona this morning into Utah, allowing for subsequent clearing/heating across southern Arizona toward the Lower Colorado River Valley. Thunderstorms will again develop and increase this afternoon especially in vicinity of higher terrain. A few instances of strong thunderstorm winds/wet microbursts could occur regionally this afternoon into evening, but the overall potential is expected to remain quite isolated and marginal overall. ...Guyer/Kerr.. 08/26/2025 $$ --- SBBSecho 3.28-Linux * Origin: ILink: CCO - capitolcityonline.net (454:3/105) .
