Supercells Fire Up Over Northern Ohio with Hail, Winds, Tornado Risk — SevereWX

Northern and central Ohio face escalating severe storm threats this afternoon and evening, per SPC Mesoscale Discussion 1007.

Storms are bubbling up along a surface front stretching from western Lake Erie into southern Michigan and northern Indiana. Moderate instability fueled by upper 60s to low 70s dewpoints and strong heating is supporting MLCAPE of 1500-2500 J/kg. Deep-layer winds of 40-50 knots aloft are promoting organized convection, including supercell structures already observed.

Primary hazards include 1-1.75 inch hail, 55-70 mph wind gusts, and a tornado or two possible up to 90 mph intensity. The most probable track focuses on northern and central Ohio counties, potentially aided by a remnant baroclinic zone into the northeast.

Uncertainty lingers on the southeast extent due to earlier convection, but coverage and severity are ramping up fast. With an 80% chance of a watch issuance, stay tuned to local NWS offices (CLE, ILN, IWX) for updates.

This fits into broader Great Lakes severe activity today—keep radar handy as storms evolve.

Preparedness tip: Have a severe weather plan ready—identify your safe spot, monitor via NOAA Weather Radio or apps, and heed warnings. Act early to stay safe.
