SPC Sep 15, 2022 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0750 PM CDT Wed Sep 14 2022 Valid 150100Z - 151200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE SOUTHERN HIGH PLAINS... ...SUMMARY... Gusty winds remain possible this evening over portions of the southern High Plains. ...Southern High Plains... Early-evening water-vapor imagery depicts a weak short-wave trough advancing east across NM into the southern High Plains. While deep-layer flow is not particularly noteworthy, isolated robust convection has developed within a steep lapse rate environment near the NM/TX border. Latest diagnostic data suggests modest instability persists across this region with roughly 1000-1500 J/kg MUCAPE. 00z sounding from AMA exhibited around 1000 J/kg but surface-6km bulk shear was only 15kt. Large-scale support ahead of the short wave is expected to aid some longevity of this activity, at least through late evening as adequate buoyancy will continue to support slow-moving convection for several hours. Gusty winds, and marginally severe hail remain possible. ..Darrow.. 09/15/2022 Read more CHECK UPDATE ZOOM GRAPHIC
