Update: 12/24/2010

The models have come into general agreement that this storm will take a more easterly path and not create a massive snow storm for central Virginia. Instead, a smaller upper level disturbance from the Midwest will likely swing through tomorrow afternoon (12/25) and tomorrow night to produce some snow showers. Local meteorologists are estimating anywhere from a dusting to an inch. The track of this storm is still uncertain, so it will still bear some watching today and tomorrow. Observation posts will be posted tomorrow if snow looks likely.
