As I mentioned this morning, this will be a long duration event (Tonight through Wednesday morning). The problem is, this will not be a constant snowfall. This will be a prolonged period of light snow with some periods of moderate snows. The moderate snows will be driven by banding that will set up associated with the inverted trough I had mentioned in my morning update. This trough, as modeled now will makes its way from around the DC/Baltimore area up through NE MD, SE PA to S NJ. In this area, that will be the areas that have the greatest accumulations. As of now, here is the NWS PHL/MtHolly's snowfall map:
Snow showers will develop late this evening throughout the region and continue through the morning hours. Much of the day tomorrow, we will have light snow showers falling. There could even be some breaks in the snow as the day progresses. The trough that we are looking to have develop will have to be something that is now-casted tomorrow during the day.Per the models, most of the day will be the light snow falling, and our best chance for accumulating snowfall will be tomorrow afternoon through the evening hours. Much of the snow will fail to accumulate on the roadways during the daytime hours. It wont get going until the sun starts setting, coinciding with the heavier precipitation. Take away message as of now, for our area, evening rush will be worse than the morning rush. Its going to be a fun day tomorrow tracking this!
Oh, and once this pushes out, get ready for some brutal cold for the weekend! Temperatures are looking downright brutal!
