The ice storm on the 7th was a minor storm in the scale of storms that have impacted us over the course of our history (a minor low travelling along the jet stream is nothing 'major' in comparison to the Superstorm or a hurricane) but its 0.35" of freezing rain that fell on the 7th and into the predawn hours of January 8th caused a bevy of problems around the Delaware Valley because of its duration, lasting nearly 24 consecutive hours. The satellite image below shows the stream of moisture coming from the Pacific northeast through Texas and into the Mid Atlantic, pulled northeast into the train of weak low pressure that rode along the jet.
Some of the video of the ice storm (above, there are three parts on YouTube that have been submitted) is shown above. The image about three minutes in of Paul Moriarty standing on a vacant Schuylkill Expressway was telling of how the ice was causing problems on area roads.
