Valid 170025Z - 170200Z The severe weather threat for Severe Thunderstorm Watch 551 continues. SUMMARY...Damaging wind threat will increase across western Kansas and the Oklahoma Panhandle over the next few hours. DISCUSSION...A weak mid-level disturbance appears to have topped the southern Rockies ridge and is now turning southeast toward the central High Plains. Over the last hour or so, scattered convection has grown upscale considerably over southeast CO within a weak low-level upslope flow regime. Precip shield/cold pool is expanding with this complex, and current trends suggest a maturing MCS may become more efficient in generating winds as the leading edge propagates into southwestern KS. With time this complex is expected to turn more southeast along the instability axis, but that will be later this evening. ..Darrow.. 07/17/2024 ...Please see www.spc.noaa.gov for graphic product...
