Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0611 PM CST Wed Mar 01 2017 Valid 020100Z - 021200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CAROLINAS INTO PARTS OF GA AND AL... ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE MID ATLANTIC SOUTHWESTWARD TO THE CENTRAL GULF COAST... ...SUMMARY... Scattered severe thunderstorms capable of damaging wind as well as isolated hail or a brief tornado remain possible this evening from the Carolinas into northern Georgia and central Alabama. ...Discussion... A broken line of storms along a cold front currently extends from central NC and SC across northern GA, central AL and into southern MS and LA. The front will continue to progress rapidly eastward, with some increasing wind fields forecast across the Mid Atlantic. As such, have expanded to the Slight Risk to include all of eastern NC. Although storms are lined up along the front as of 00Z, several cellular entities are embedded or even just ahead of the wind shift. With strong wind shear including effective SRH in excess of 300 m2/s2, supercells will remain possible mainly across the Carolinas and northeast GA where damaging wind, isolated hail and perhaps a brief/weak tornado could occur although instability is a bit lacking with relatively high T/Td spreads. A southward-moving outflow boundary will also limit areal extent of any wind/tornado threat, currently carving out parts of northeastern NC. For more information see MCD 250 and 251. ..Jewell.. 03/02/2017Read more
