Sometimes it's easier to see the extent of the damage and get a better idea of the cause from a drone above. You can see the turning of the winds better in this image than the one to the immediate left. (Coutesy: Van Wert EM Rick McCoy) |

Environment
Figure 1, 5:00 PM EDT 22 June 2018: The surface map above shows a surface low with associated warm and cold front over east-central Indiana. Heavy rainfall fell near and along these surface features This warm front was also a key forcing mechanism for the tornado near Van Wert, OH. | Figure 2, 7:00 PM EDT 22 June 2018: The green lines on this image show the heights of the LCL (Lifting Condensation Level). The LCL is an estimate of cloud base height. Over northern Indiana and northwest Ohio, the LCLs are near 500 meters (~1,600 feet). This is rather low. Low LCLs are favorable for tornadic development. | Figure 3, 7:00 PM EDT 22 June 2018: The red lines on this map show the amount of CAPE (Convective Available Potential Energy) that was available. An area of 1,000 j/k was available along and south of the surface warm front. This modest value was enough to support some thunderstorms. |
Figure 4, 7:00 PM EDT 22 June 2018: In northwest Ohio, there was about 10-15 knots (12-17 mph) of wind shear in the lowest 1 km of the atmosphere. In this example, shear measures the difference between the surface wind and the wind at 1-km above the ground. These values are modest as well, but were capable of producing a tornado. | Figure 5, 5:00 PM EDT 22 June 2018: Precipitable water values over our area ranged from 1.5-1.1.7 inches. This measures the amount of available water within a column of the atmosphere. These values are above the normal ~1.0 inch for this date, which helped promote heavy rainfall. |
