Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0743 PM CDT Sat Aug 10 2019 Valid 110100Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHERN ROCKIES/HIGH PLAINS AND THE CENTRAL HIGH PLAINS... ...SUMMARY... Scattered severe thunderstorms will continue this evening across the northern Rockies region into the central High Plains. Wind and hail remain the primary threats. ...01z Update... Scattered robust convection continues across the northern Rockies, arcing east-southeast over southern MT into the Black Hills region. This activity is partly driven by a weak short-wave trough that is ejecting across western MT ahead of the main Pacific northwest trough. Given the large-scale support, scattered severe thunderstorms should focus along a corridor primarily across southern MT into northeast WY through late evening. Farther south across the central High Plains, scattered thunderstorms developed within easterly low-level flow regime over northeast CO/southwest NE. This activity is beginning to cluster and an MCS may ultimately evolve over south-central NE/north-central KS along nose of LLJ. Have adjusted severe probs to account for this higher severe probability development. ..Darrow.. 08/11/2019Read more
