SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1129 AM CST Thu Mar 08 2018 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are expected to evolve overnight from the western Gulf Coast region north into the Ozarks vicinity. ...Synopsis... Some deamplification of the upper flow field across the U.S. is expected Friday, as the upper low over the Northeast shifts north into the Canadian Maritimes, leaving a flatter cyclonic flow to prevail over the eastern three-quarters of the country. Embedded within the weak cyclonic flow, a subtle short-wave trough is forecast to emerge from the southern Rockies and shift into the southern Plains Friday evening/overnight. In response, low-level southerly flow advecting somewhat higher theta-e air northward atop a still-stable boundary layer may support development of scattered/elevated showers and possibly a few embedded thunderstorms across portions of the south-central U.S. from east Texas/Louisiana north to the Ozarks. With any storms which can form expected to remain elevated, and both cloud-layer shear and CAPE expected to remain rather modest, any severe risk appears at this time to be less than 5% probability. Elsewhere, thunderstorms are not expected. ..Goss.. 03/08/2018 Read more
