| Brief Description: The combination of an upper-level disturbance, increasing atmospheric shear, and ample instability set the stage for a major severe weather episode across portions of eastern West Virginia during the late afternoon and evening. The episode was highlighted by supercell thunderstorms which produced two multi-county tornadoes and several instances of large hail. For many residents of the Potomac highlands, the storms were a watershed event; the locals believed that tornadoes "like those in the midwest and Great Plains" could never strike. The first twister, originally associated with a supercell which had produced a long (11-13 mile track) tornado in Somerset Co, Pennsylvania, re-emerged in extreme northeastern Mineral Co just east of Wagoner. The storm crossed into Hampshire Co, then passed an Allegheny Power substation before causing minor damage at some homes just north of Donaldson. Damage included a destroyed gazebo, stripped siding/trim from homes, and several uprooted or snapped trees. The tornado crossed River Mountain, causing damage primarily to forested areas. The path continued across the South Branch of the Potomac River before the tornado dissipated just outside the town of Levels. The second tornado produced significantly more property damage. Initial reports of a funnel cloud over Bloomington, Maryland (Garrett Co) became prophetic as the first touchdown occurred 5 miles southwest of Keyser. Damage increased as the storm descended the Allegheny front range (Green Mountain). A car was blown over, a garage destroyed, and several trees were snapped or uprooted. A pine tree landed on one home, another home sustained minor damage, and a nearby mobile home had its skirting blown off. The twister crossed New Creek Mountain, levelling numerous trees in heavily forested areas. Damage intensified after the tornado descended the mountain. One mobile home was destroyed - and, after the storm crossed federal highway 220, more tree damage was noted, as was minor damage to homes and extensive damage to outbuildings. The storm continued along federal highway(s) 50/220 to Ridgeville, rolling one mobile home, causing minor damage to nearby buildings, and destroying a barn near the Mill Creek Country Club just west of Burlington. From there, the tornado continued over Patterson Creek Mountain and into Hampshire Co, where several mobile homes were damaged or rolled along Davy Road. Five persons in one of the homes sustained minor injuries; only one accepted transport to a local hospital for head trauma. A station wagon was completely turned around and sustained minor damage. The twister then tracked three miles south of Junction, where it likely dissipated. Hail was associated with each mini-supercell - and several residents, including fruit farmers, noted varying amounts of damage due to prolonged and, in some cases, sizeable hail. One grower reported total damage to his orchard (near Levels); other damage was seen in the form of stripped leaves and downed small limbs. Conditions quieted after the final supercell (that which produced the second tornado) passed. | |||||||||||
