Discussion
Our very active weather pattern continues for the foreseeable future and it looks like it will bring accumulating snow to the Philly metro region from later tonight into early Wednesday. In addition, it'll turn very cold for the Thursday/Friday time period and then absolutely frigid this weekend with zero degree readings on the table and perhaps the coldest Valentine's Day (Sunday) in a long, long time. On top of all that, there is the chance for more snow next week. Powerful low pressure this morning is moving slowly to the northeast just off the coast and the Philly metro region will likely escape without any of its precipitation, but a slushy, small accumulation of snow is possible this morning along coastal New Jersey. Another low pressure system will trek across the Great Lakes and Ohio Valley later tonight and Tuesday and it will transfer its energy to a coastal storm that will produce an extended period of snow in the region with accumulations. This type of system has the chance to produce accumulations on the order of a couple of inches-to-several inches for much of the Philly metro region, but confidence is not too high yet as to exactly where that total snowfall accumulation pattern will set up later tonight and Tuesday. There will be small-scale or mesoscale bands of snow setting up somewhere in the Mid-Atlantic region on Tuesday producing heavier snowfall amounts in localized areas with lesser amounts in nearby regions. The preliminary snowfall estimate for the region is 3-6 inches by early Wednesday with the higher amounts more likely to the south and west of the Philly metro region (e.g., Chester, Delaware Counties). Stay tuned - its a challenging forecast.
