SPC Sep 14, 2022 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0757 PM CDT Tue Sep 13 2022 Valid 140100Z - 141200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF NEW ENGLAND... ...SUMMARY... Storms capable of isolated damaging wind gusts will remain possible across parts of New England until around 10-11 PM EDT. ...New England... A band of storms moving across southern NH into eastern MA has a history of producing sporadic damaging wind gusts, though a gradual weakening trend has been noted with the onset of nocturnal cooling/stabilization. MLCAPE of around 500 J/kg and effective shear of 35-45 kt will continue to support occasionally organized storm structures, which could pose a threat of isolated damaging wind gusts and perhaps a brief tornado into late evening, before the severe threat wanes overnight as storms continue to weaken with time. ..Dean.. 09/14/2022 Read more CHECK UPDATE ZOOM GRAPHIC
