MD 0674 CONCERNING SEVERE THUNDERSTORM WATCH 192... FOR PORTIONS OF CENTRAL AND EASTERN OKLAHOMA Mesoscale Discussion 0674 NWS Storm Prediction Center Norman OK 0515 PM CDT Fri May 08 2026 Areas affected...portions of central and eastern Oklahoma Concerning...Severe Thunderstorm Watch 192... Valid 082215Z - 090015Z The severe weather threat for Severe Thunderstorm Watch 192 continues. SUMMARY...Threat for large to very large hail continues across portions of central and eastern Oklahoma. DISCUSSION...Supercells continue to increase in coverage along the cold front sagging southward into central/eastern Oklahoma. Hail up to 2.75 inches and winds gusts to 60 mph have been reported with the northern cells in Osage County. Supercells will continue eastward in the Oklahoma City Metro and Tulsa Metro this evening. The environment downstream remains very favorable for large hail (1.5-2+ inches) with steep low to mid-level lapse rates and moderate MLCAPE. This has been well sampled in the 20z RAOB from OUN, where lapse rates around 7 C/km extend through the profile and 45 kts of 0-6 km shear. Given dew point depressions around 20-25 F, the threat for damaging wind will continue, possibly increasing into the evening as cells cluster and tend to grow upscale. ..Thornton.. 05/08/2026 ...Please see www.spc.noaa.gov for graphic product...
