Mesoscale Discussion 0857 NWS Storm Prediction Center Norman OK 0649 PM CDT Mon May 20 2024 Areas affected...Central Michigan and far northern Indiana Concerning...Severe Thunderstorm Watch 268... Valid 202349Z - 210115Z The severe weather threat for Severe Thunderstorm Watch 268 continues. SUMMARY...A bowing line segment or two capable of producing severe wind gusts near 60-70 mph remains possible across central MI. Further south into Lower MI, a few thunderstorms could produce marginally severe hail around 0.75 to 1.25" in diameter. DISCUSSION...A broken line of thunderstorms associated with an MCV moving east across central MI and northern IN is expected to maintain localized intensity through this evening. Although buoyancy across central MI is fairly limited and convective inhibition will continue to increase through nightfall, easterly surface flow downstream should continue to support a relatively balanced convergence zone. In addition, low-level shear vectors orthogonal to the line and magnitudes east of the MCV's center point may be favorable for a mesovortex or two. However, LCLs downstream of the line become increasingly unfavorable for tornadogenesis. ..Barnes/Thompson.. 05/20/2024 ...Please see www.spc.noaa.gov for graphic product...
