SPC Jul 25, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0234 AM CDT Mon Jul 25 2022 Valid 271200Z - 281200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE MID-ATLANTIC WEST TO SOUTHERN MISSOURI...AND ACROSS PORTIONS OF THE CENTRAL PLAINS... ...SUMMARY... Isolated severe thunderstorms with damaging winds will be possible from the mid-Atlantic coast to the Ohio Valley on Wednesday. Isolated severe storms over the central Plains may produce severe hail and damaging gusts. ...Mid-Atlantic to southern Missouri... An east-west surface front will extend from the mid-Atlantic coast west to near the KS-OK border Wednesday afternoon. Ongoing morning clouds/precipitation will influence subsequent differential heating/destabilization in the vicinity of the front, however it appears that pockets of moderate buoyancy will once again develop during the afternoon. The front resides along the southern extent of stronger westerly mid-level flow (35-40 kts), and this will support the potential for a few clusters of strong to severe storms capable of primarily damaging winds. ...Central Plains... Isolated thunderstorm development will be possible across the central High Plains Wednesday afternoon in an environment with effective shear 35-40 kts and MLCAPE approaching 1500 J/kg. Initial supercell structures may evolve into a southeast-moving cluster during the evening with an attendant isolated severe hail and wind threat. ..Bunting.. 07/25/2022 Read more CHECK UPDATE ZOOM GRAPHIC
