SPC Sep 2, 2023 0600 UTC Day 1 Convective Outlook

LIVE MAP (ABOVE) ... SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1231 AM CDT Sat Sep 02 2023 Valid 021200Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the continental United States Saturday. ...Discussion... Upper low currently located along the northern CA Coast will move little during the period, but slowly weaken as heights rise across much of the western US, including the Great Basin. While seasonally strong mid-level flow will extend through the base of the trough across southern CA into the eastern Great Basin, thermodynamic environment will likely not prove too conducive for organized severe updrafts Saturday. Forecast soundings exhibit modest lapse rates and overall weak buoyancy across much of this region. Even so, a few robust updrafts appear possible across the lower CO River Valley, where surface temperatures will be notably warmer than higher latitudes. Elsewhere, scattered thunderstorms will develop near the central Gulf Coast, but weak flow and poor lapse rates will not support an appreciable risk of severe. Isolated thunderstorms are also expected to evolve across portions of the Great Lakes region within a strengthening warm advection regime. Forecast soundings suggest this activity will also be too weak to warrant a severe threat. ..Darrow/Wendt.. 09/02/2023 Read more CHECK UPDATE ZOOM GRAPHIC
