A potent area of low pressure tracked through the Midwest on the 9th. As the low approached the Mid-Atlantic coast, this system phased with energy in the southern branch of the jet stream to cause strong low pressure to develop just off the Delmarva peninsula. The low continued to rapidly strengthen as it moved off to our northeast on the 10th.
The system spread snow across West Virginia that began on the 9th and lasted into the 10th. Significant snow accumulations were reported with this storm. As the low pressure rapidly intensified on the 10th, strong winds caused blowing and drifting snow that led to blizzard conditions.
