Wednesday - Thursday Snowstorm

          This will be more of an unexpected snowstorm event. I was originally thinking light accumulations overall but now the models have really blown up this storm and indicate possible significant accumulations across. So you may be slightly surprised by what I am about to say but it looks some area's in southern Pennsylvania over to the astern Appalachians could see 6 - 10 inches of snow. The timing of this storm is the storm will move into southern Pennsylvania at about 3 PM Wednesday as likely all snow with some mix possible in the city of Philadelphia. After that heavier precipitation will move into southern Pennsylvania, especially the lower Susq. Vally, after that the precipitation will continue to move northeast into Central and northern New Jersey. This is by about 8 PM. Now very heavy precipitation will move into area's like Harrisburg, PA, York, Pa, Lancaster, PA, Allentown, PA, Trenton, NJ, West Orange, NJ, and possibly NYC. By 7 AM, the precipitation should be leaving southern Pennsylvania and New Jersey. It also looks like southern New England could also get in on some snow. It looks like a widespread 2 - 4 inches across Massachusetts, as well as Connecticut and Rhode Island. As you go further north into Vermont and New Hampshire, you will be looking at 1 - 3 inches around. So here is a forecast map for snowfall totals expected  out of this storm.

          Here is an example of a trending model. Earlier and yesterday the CMC model was showing little to no impacts on the northeast with this storm, now look at the precipitation that the CMC apits out to be falling Wednesday night!
