MD 1057 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR WESTERN AND CENTRAL OKLAHOMA
Mesoscale Discussion 1057 NWS Storm Prediction Center Norman OK 1238 AM CDT Sun Jun 01 2025 Areas affected...Western and Central Oklahoma Concerning...Severe potential...Watch possible Valid 010538Z - 010815Z Probability of Watch Issuance...40 percent SUMMARY...An isolated severe threat will likely continue through the early morning hours, and an increase in the threat is possible. If storms continue to intensify, then a severe weather watch may be needed. DISCUSSION...An east-to-west band of strong thunderstorms, associated with isolated severe, is ongoing across northern Oklahoma. The storms are located near a front, and are being supported by large-scale ascent ahead of a shortwave trough moving southward through Kansas, evident on water vapor imagery. An axis of low-level moisture is located from northwest Texas into western Oklahoma, where surface dewpoints are in the mid to upper 60s F. This is contributing to MLCAPE in the 1000 to 1500 J/kg range across much of western Oklahoma. RAP forecast soundings near the instability max have effective shear near 40 knots, with 700-500 mb lapse rates near 7 C/km. This should support a threat for isolated large hail within the stronger cores. A capping inversion is present, which will keep the storms elevated. However, an isolated severe gust will be possible with the strongest of cells. ..Broyles/Bunting.. 06/01/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TSA...OUN...AMA...
