SPC Apr 4, 2022 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0800 PM CDT Sun Apr 03 2022 Valid 040100Z - 041200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PARTS OF OKLAHOMA INTO WEST TEXAS... ...SUMMARY... Isolated severe wind gusts and marginally severe hail are possible for portions of Oklahoma into west Texas this evening. ...Southern Great Plains... Early evening water-vapor imagery implies a weak disturbance moving east into the southern High Plains early this evening. A cold front draped from eastern KS south-southwestward through western OK and into the TX South Plains will continue south and southeast acting to aid in at least isolated thunderstorm development. Although low-level moisture remains limited (surface dewpoints in the upper 40s to lower 50s deg F), steep lapse rates have contributed to weak buoyancy this evening across the southern Great Plains (reference 00z Norman, OK raob; 600 J/kg MUCAPE). A strong/veering wind profile with height will support some storm organization with a few of the stronger storms this evening being capable of an isolated hail/wind risk. As the boundary layer cools this evening, storm intensity will likely begin to wane by late evening. ..Smith.. 04/04/2022 Read more CHECK UPDATE ZOOM GRAPHIC
