| Episode Narrative | A leading surface boundary sagged from lower Michigan across the Southern Tier and Genesee Valley. Ample moisture pooling evidenced by precipitable water values in excess of 1.5 inches and modest shear generated instability that allowed for thunderstorms to vertically develop into a layer of dry air aloft. This provided the first set of wind damage producing thunderstorms. Subsequent to those, the Lake Ontario lake breeze forced additional thunderstorms that keyed on much higher low level helicity that moved southeastward from Genesee to Ontario counties. These storms developed notable rotation, resulting in one tornado in Monroe County. |
| Event Narrative | A supercell thunderstorm developed over Genesee County and tracked east-southeast from just south of the interchange of the New York State Thruway and I-490. Scattered tree limb damage consistent with straight line winds was found along the Oatka Creek upon following the path of this storm into Monroe County starting just east of Beulah Road and continuing through Mumford. Damage became more concentrated upon crossing Wheatland Center Road and entering Oatka Creek Park. A grassy field was laid down flat in the opposite direction of the storm motion with tree damage to the south end of the field indicating rotation with several damaged trees having broken to the northeast. Farther east, a partially- flattened corn field with two shallow-rooted uprooted trees along its southern periphery was coupled with several broken trees along a hiking path through Oatka Creek Park indicating opposing directional damage. Scattered damage continued farther east from Oatka Creek Park along Quaker Road south of Scottsville. A second more concentrated area of damage was found near the intersection of Quaker Road and Route 251. Several trees were downed along the hillside west of Route 251, into Route 251, and on the property at the southeast corner of Route 251 and Quaker Road. This included at least three uprooted shallow-rooted trees and one approximately five foot diameter broken and twisted hardwood tree along with many downed smaller limbs that indicated a convergent damage path. Due to the fact that the majority of the path of this storm was along Oatka Creek and through the Oatka Creek Park and in an area that is primarily rural, there was no damage to any structures. Because of this, the National Weather Service use exclusively tree damage indicators to reach a conclusion of an EF0 strength and maximum wind speed of 75 mph. |
