SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0733 PM CDT Sat Mar 30 2024 Valid 310100Z - 311200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE WEST VIRGINIA AREA... ...SUMMARY... Isolated severe thunderstorms will persist this evening across portions of the West Virginia region. Marginally severe hail is the primary risk. ...01z Update... Low-amplitude short-wave trough is progressing across the northern middle Atlantic region, and short-wave ridging is now evident in water-vapor imagery across the OH Valley. This lead feature appears partly responsible for the corridor of convection that is sagging southeast across southern PA-northern WV-extreme southern OH. More isolated convection lingers along the OH River into southern IL. Strong boundary-layer heating and steep lapse rates have aided updraft intensity along the western flank of this activity. A small cluster of strong/severe convection will propagate across northern WV over the next few hours, but will increasingly encounter weaker buoyancy downstream where temperatures/dew points are notably lower. While the primary feed into these updrafts is from the west, nocturnal cooling will also lead to weaker buoyancy and the overall severe threat should gradually wane by late evening. Until then, isolated marginally severe hail may accompany this activity. ..Darrow.. 03/31/2024
