118 ACUS01 KWNS 160043 SWODY1 SPC AC 160042 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Wed Oct 15 2025 Valid 160100Z - 161200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN/CENTRAL ROCKIES INTO THE ADJACENT HIGH PLAINS... ...SUMMARY... Isolated strong to severe thunderstorms are possible tonight across parts of the southern/central Rockies into the High Plains. Occasional large hail and severe wind gusts may occur. ...01Z Update... ...Southern/Central Rockies into the central High Plains... Scattered thunderstorms are ongoing across the region, downstream of a deep upper low moving across the Great Basin. Despite the loss of daytime heating and much of the surface-based buoyancy, thunderstorms will likely persist throughout the evening and tonight amid cool mid-level temperatures and related steep mid-level lapse rates. Moderate vertical shear will persist throughout the evening and overnight as well, with the resulting combination of buoyancy and shear sufficient for a few supercells and an isolated severe risk. Additional information about this area is available in MCD #2148. ..Mosier.. 10/16/2025 $$
