adOverview
A cold front moved into northwest Ohio the evening of Thursday, June 15. A weak surface low pressure developed along this front over southern Michigan earlier in the day and moved southeast across the western tip of Lake Erie during the evening. A warm front extended southeast of this low pressure along the western Lake Erie shoreline and then down towards central Ohio. Thunderstorms erupted along the cold front near Toledo just before 6:00 PM and moved southeast towards east-central Ohio over the coming hours. Enhanced shear associated with the low pressure, warm front, and lake breeze boundary near the western lakeshore allowed storms to rotate. A particularly intense supercell (rotating thunderstorm) developed near the Ohio/Michigan border just north of Toledo and tracked across parts of Lucas, Ottawa, Sandusky, Erie, Huron, Seneca, Richland, Ashland, and Wayne Counties. This supercell was responsible for 12 tornadoes and numerous instances of large hail, with hail to at least the size of tennis balls reported near Toledo and multiple reports of hail to golf ball sized or larger as the storm continued southeast. Storms gradually congealed into a line that produced some hail and straight line wind damage into east central Ohio. |

Hail:
The long tracked supercell thunderstorm produced a swath of large hail from eastern Lucas County southeast across parts of Ottawa, Sandusky, Erie, Huron, northern Richland, Ashland and Wayne Counties with numerous reports of hail larger than golf ball sized. The largest hail occurred in eastern Lucas County, with reports of hail near baseball sized in locations such as the Point Place neighborhood in Toledo, Harbor View, and the Cedar Point Wildlife Refuge. Hail larger than 2" in diameter was also reported in northern Ashland County. Another thunderstorm produced quarter to golf ball sized hail in Seneca County.

Radar
MRMS max estimated hail size (in inches) through 11 PM June 15, 2023. Locations in green reported hail between quarter and golf ball-sized, locally larger. Locations in yellow reported hail larger than golf ball and up to at least tennis ball sized. | MRMS mid-level rotation swaths through 11 PM June 15, 2023. Note the long swath of moderate to strong rotation, associated with the dominant supercells. At times, you can see tracks of smaller cells getting ingested by the larger supercell. The supercell produced the bulk of the large hail and tornadoes, though some of the smaller cells that developed and moved into it also produced tornadoes. | Loop of the reflectivity (left) and velocity (right) from the TDTW radar valid 6:01 to 6:14 PM as a tornado developed and moved across northern Toledo and Point Place. The tornado developed just south of the stateline near US 24 at 6:06 PM before moving into the Maumee off of Point Place at 6:10 PM. The tornado clipped the shoreline near Harbor View around the end of this loop. | Loop of the reflectivity (left) and velocity (right) from the TDTW radar valid 6:19 to 6:31 PM. After grazing the shoreline near Harbor View at around 6:15 PM, the rotation stayed over Maumee Bay for a few more minutes (where videos of a waterspout were recorded) before coming back ashore near the Maumee Bay State Park as an EF-0 tornado. |
Cross section of the supercell thunderstorm near the Lucas County shoreline at 6:16 PM June 15, 2023. Note the very large area of high returns extending from the ground to over 35,000 feet aloft, with purples in the 10,000-20,000 foot layer indicating very large hail. Hail to near baseball size was reported around this time in eastern Lucas County. | Loop from the KCLE radar valid 6:46 PM through 6:59 PM of the rotation that produced an EF-2 tornado near Oak Harbor in Ottawa County. The tornado touched down at 6:49 PM just north of the Ottawa/Sandusky County line and lifted around 6:58 PM east-southeast of Oak Harbor. The storm that produced this tornado was a smaller storm getting ingested into the larger supercell approaching from the northwest. | Reflectivity (upper left), velocity (upper right), correlation coefficient (bottom left), and normalized rotation (bottom right) from the KCLE radar valid 6:55 PM June 15, 2023. Note the area just south of Oak Harbor where lower correlation coefficient is co-located with a tight velocity couplet within an area of high reflectivity. This is a Tornado Debris signature, which was present for 2-3 radar scans with this tornado. | Reflectivity (left) and velocity (right) valid at 7:01 PM June 15, 2023 from the KCLE radar. The radar is detecting a small area of rotation between Lindsey and Oak Harbor, which is likely responsible for the brief tornado that occurred in Rice Township. This was a brief EF-0 tornado with rotation that was tricky to spot on radar. |
Reflectivity (left) and velocity (right) valid at 7:19 PM from the KCLE radar as an EF-0 tornado is produced in Vickery, OH. | Reflectivity (left) and storm-relative velocity (right) valid at 7:49 PM from the TLVE radar as an EF-0 is produced in Bellevue, OH. This is one of the tornadoes with a more subtle radar feature associated with it. | Reflectivity (top left), velocity (top right), storm-relative velocity (bottom left), and normalized rotation (NROT; bottom right) displayed from KCLE radar for 7:31 PM to 8:24 PM. In this radar loop you can see a supercell track southeast across Huron County as it produces several tornadoes, the strongest of which produced EF-2 damage in Peru, OH. Many classic supercell features are observed here including the hook echo, inflow region, and a very strong mesocyclone. Rain showers near the mesocyclone were also ingested into the supercell as it intensifies. | Reflectivity (left) and velocity (right) valid at 8:46 PM from the KCLE radar as an EF-0 tornado is produced in Nankin, OH. |

Environment
Surface low pressure developed over Southeast Michigan on Thursday June 15, 2023 in advance of an upper level trough deepening across the Central Great Lakes. A jet streak at 500mb rounded the base of the trough during the evening, supporting severe thunderstorm development. Effective bulk shear increased to 40-50 knots during the evening across northwest and north central Ohio. Meanwhile a warm front extended southeast from near Toledo towards Ashland, with this warm front likely becoming enhanced by a lake breeze near the western shoreline of Lake Erie in parts of Lucas, Ottawa, and Sandusky Counties.
June 15,2023 8 PM 300mb obs, wind, divergence | June 15, 2023 WPC Surface Analysis/Fronts Loop | June 15, 2023 8 PM Effective Bulk Shear |
At 6 PM surface low pressure was located near the west end of Lake Erie and the Toledo area. The temperature at Toledo peaked at 83 degrees at 7:01 PM EDT, right after the tornadic supercell had moved through Lucas County. The dewpoint reached 61 degrees ahead of the storms. The atmosphere became considerably more favorable for severe thunderstorms development between 4 and 7 PM as southwest winds ramped up, pushing mixed layer CAPE from around 500 J/kg to 1500 J/kg across Northwest Ohio. Storms moving southeast out of Michigan encountered very strong and rapidly increasing surface vorticity as they approached the Lake Erie shoreline due to the warm front and lake breeze. This resulted in the tornado developing just north of Toledo at 606 PM EDT and a tornado developing at 609 PM EDT a half mile north northwest of Detroit Beach in Monroe County, Michigan.

One parameter that was not as favorable for tornado development was the Lifting Condensation Level or LCL. The LCL was estimated to be around 1250 m when the first tornado occurred. Values of 500-800 m are more conducive to tornado development. More investigation is needed to see if values may have actually been lower in the vicinity of Lake Erie. Two other parameters that were worth noting with relatively high values for Ohio include the Supercell Composite Parameter which peaked at 4 and the Large Hail Parameter which peaked at a value of 8.
