As the massive coastal low continues to move away from the northeast, we have a huge upper level trough (cold air aloft) that will pin-wheel through our area late tonight into early Wed. morning. As a result, there will be "spokes" of moisture rotating through our area resulting in intermittent snow and flurries overnight, Tuesday, Tuesday night and ending very early Wednesday morning. A secondary coastal storm will develop and head out to sea. The upper level energy moving through (by itself) has the potential to bring accumulating snow to the region starting late tonight. With this storm setup, we also have to monitor the potential for heavier snow bands setting up.
Late tonight, Tuesday and Tuesday night we expect intermittent snow and flurries (over an extended period of time) that will generally be light to moderate. We do NOT expect a major storm with this. Flurries or snow showers could linger into Wednesday and Thursday.
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 expected from Philadelphia to Lancaster and York (4-6" possible).
After these systems move through, the temperatures for the second half of the week and the weekend will be very cold. In fact, Valentine's weekend looks to be VERY cold indeed!
