SPC Mar 8, 2022 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1138 PM CST Mon Mar 07 2022 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL GULF COAST... ...SUMMARY... A marginal risk for severe thunderstorms may develop tonight over parts of the central Gulf Coast. ...Central Gulf Coast... An upper-level trough will move across the Great Plains this afternoon and evening as southwest mid-level flow remains in place over the Southeast. A low-level jet will develop near the Texas coast and move east-northeastward across the lower Mississippi Valley, as a cold front advances southeastward across the region. Ahead of the front, moisture advection will occur across the central Gulf Coast. In response, a pocket of moderate instability is forecast to move from the northern Gulf of Mexico into far southeast Louisiana and far southern Mississippi this evening. Thunderstorms are expected to develop near the front during the evening, where low-level convergence will be maximized. These storms should persist into the overnight period as the front moves southeastward across the region. NAM forecast soundings from New Orleans to near Biloxi at 06Z tonight generally have MUCAPE near 1200 J/kg with effective shear around 50 knots. This should be enough for marginally severe hail and a few strong wind gusts with the stronger cells. Large-scale ascent should remain relatively weak suggesting any severe threat will remain localized and confined to the coastal areas of Louisiana, Mississippi, Alabama and far western Florida. The threat should be greatest from 06Z to 12Z later tonight. ..Broyles/Squitieri.. 03/08/2022 Read more CHECK UPDATE ZOOM GRAPHIC
