Strong to Severe Storms Possible Friday

Another upper-level storm system will track through the region Friday, bringing the opportunity for strong to severe thunderstorms this afternoon and evening in Central Virginia. The surface low pressure system associated with the upper disturbance will track just to the west of the mountains in western Virginia, and continue to our North and Northeast this afternoon and evening.
This path will keep Southerly and Southwesterly flow into the Commonwealth, with dew point temperatures in the low to mid 70's (indicating ample low-level moisture to fuel newly developing thunderstorms) and bring sufficient lift over the state for strong to severe thunderstorms.
The primary threat out of these storms will be strong, straight-line winds. However, an isolated tornado cannot be ruled out, and some storms may also produce large hail.
