888 ACUS01 KWNS 280055 SWODY1 SPC AC 280053 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0753 PM CDT Wed Aug 27 2025 Valid 280100Z - 281200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE CENTRAL HIGH PLAINS... ...SUMMARY... Isolated strong to severe thunderstorms remain possible across parts of the central High Plains early this evening. ...01z Update... Scattered convection persists across much of the western United States early this evening, primarily driven by strong boundary-layer heating. Much of this activity will gradually weaken as the evening progresses. A corridor of modest instability persists across the central High Plains and a few small clusters are noted across eastern Colorado into southwest Kansas. Weak low-level warm advection will maintain this activity into the mid-evening hours, with some upscale growth possible downstream later tonight as LLJ strengthens. Even so, most of this convection should remain sub-severe. ..Darrow.. 08/28/2025 $$
