MD 0759 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF CENTRAL LOWER MICHIGAN Mesoscale Discussion 0759 NWS Storm Prediction Center Norman OK 0522 PM CDT Sun May 17 2026 Areas affected...portions of central Lower Michigan Concerning...Severe potential...Watch possible Valid 172222Z - 172315Z Probability of Watch Issuance...40 percent SUMMARY...A few instances of severe hail may accompany multicells and isolated supercells over the next few hours. DISCUSSION...Widely scattered multicells and supercells continue to traverse a WAA regime to the north of a warm front. Given 50+ kts of effective bulk shear near these storms, severe hail may still occur with the strongest updrafts. Nonetheless, the severe threat is expected to be more on the sparse side. Conditions will continue to be monitored for the need of a WW issuance should storms experience a rapid trend in intensification, or become more widespread. ..Squitieri/Smith.. 05/17/2026 ...Please see www.spc.noaa.gov for graphic product...
