Mesoscale Discussion 0189 NWS Storm Prediction Center Norman OK 1157 PM CDT Fri Mar 14 2025 Areas affected...southwestern Lower Michigan and northern Indiana Concerning...Severe potential...Watch likely Valid 150457Z - 150600Z Probability of Watch Issuance...80 percent SUMMARY...Potential for damaging winds will spread eastward into northern Indiana and southern Lower Michigan over the next couple of hours. DISCUSSION...Latest RAP-based objective analysis shows only weak buoyancy across southern Lower Michigan and northern Indiana, but very strong flow aloft exists ahead of the advancing upper low. As such, and given dry lower-tropospheric air across the region providing evaporative potential, it appears that locally damaging winds will remain possible with the advancing band of convection now crossing northern Illinois. As such, new WW issuance may be required. ..Goss/Mosier.. 03/15/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...IWX...GRR...IND...LOT...
