We expect intermittent snow and flurries over an extended period of time, from today through tomorrow morning, that will generally be light to moderate. Could see heavier snow bands set up through this time period, and of course we will monitor the radar and bring you updates.
Here is the setup: The strong coastal low continues to move away from the northeast, but could interact with another system swinging through. That system is a huge upper level trough (cold air aloft) that is pin-wheeling through our area. As a result, there will be "spokes" of moisture rotating through our area resulting in intermittent snow and flurries today, tonight and ending very early tomorrow morning. A secondary coastal storm will develop and head out to sea. The location and track looks uncertain as the models show. Possible scenarios could be stealing energy away from the trough and take away some moisture or developing just close enough to impact us as a coastal storm. This development should be established by this afternoon. Either way the upper level energy, by itself, is bringing accumulating snow to the area. The heavier snow band set up and development of a coastal storm are events we will monitor through the day.
Through tomorrow morning a general 2-4" is expected for most parts of our area with locally higher amounts in some spots (where the heavier bands set up). Higher amounts around 4-6" possible from Philadelphia to Lancaster and York. Still some instability left for tomorrow afternoon through the weekend, expect flurries or a snow shower at any point.
The temperatures for the rest of the week and the weekend will be very cold. Presidents' Day weekend will have lows near 0 degrees and highs in the teens…especially on Valentine's Day Sunday. Presidents' Day Monday, still cold but highs back into the mid 20s.
