764 ACUS11 KWNS 012152 SWOMCD SPC MCD 012151 SDZ000-NEZ000-012315- Mesoscale Discussion 1506 NWS Storm Prediction Center Norman OK 0451 PM CDT Mon Jul 01 2024 Areas affected...Northern High Plains Concerning...Severe Thunderstorm Watch 494... Valid 012151Z - 012315Z The severe weather threat for Severe Thunderstorm Watch 494 continues. SUMMARY...Convection should continue increasing across the northern High Plains this evening. DISCUSSION...Mid-level short-wave trough is currently progressing across eastern MT/WY, per latest water-vapor imagery. Notable synoptic front has now surged across western ND, arcing through western SD into central WY. Scattered robust convection has evolved along this boundary and the strongest storms are now growing upscale as larger clusters begin to emerge. Over the next few hours there is increasing confidence that a corridor of significant convection will materialize from Bennett County SD to east of Mobridge, coincident with a pre-frontal axis of higher buoyancy. ..Darrow.. 07/01/2024 ...Please see www.spc.noaa.gov for graphic product...
