MD 0518 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF LOWER MI...EASTERN/CENTRAL IN...AND WESTERN OH Mesoscale Discussion 0518 NWS Storm Prediction Center Norman OK 0122 PM CDT Fri Apr 24 2026 Areas affected...Parts of lower MI...eastern/central IN...and western OH Concerning...Severe potential...Watch unlikely Valid 241822Z - 242045Z Probability of Watch Issuance...5 percent SUMMARY...A few strong storms capable of producing locally damaging wind gusts are possible through the afternoon. DISCUSSION...A broken band of thunderstorms is moving eastward across parts of central lower MI, where subtle midlevel height falls are occurring ahead of a midlevel trough approaching from the west. While poor midlevel lapse rates and modest boundary-layer moisture (middle 50s dewpoints) are limiting buoyancy ahead of these storms, around 35 kt of midlevel south-southwesterly flow preceding the trough and steepening low-level lapse rates could support a couple strong/loosely organized cells/clusters capable of locally damaging wind gusts. While large-scale forcing for ascent decreases with southward extent, a similar environment may support a couple strong storms with an attendant risk of locally damaging gusts across central/eastern IN into western OH as well. ..Weinman/Guyer.. 04/24/2026 ...Please see www.spc.noaa.gov for graphic product...
