Mid-Atlantic region…two storms to deal with this week

Given the storm track of this initial system well to the north and west of the I-95 corridor, the urban areas from DC-to-Philly-to-NYC should experience enough warming to prevent any serious icing issues later in the day and tonight.  Precipitation will be only spotty and light this afternoon and evening and, by the time the heavier stuff arrives later tonight, it should be warm enough at low-levels for primarily plain rain in the immediate I-95 corridor. Any significant icing problems later tonight should be confined to locations well to the north and west of the DC, Philly, NYC urban areas.  While temperatures will climb only slowly today to slightly above the freezing mark, they could rise late tonight when the heavier precipitation arrives and they should reach well up into the 40’s on Tuesday in DC, Philly and NYC.

While this initial storm system is looking somewhat warmer than it did a few days ago for the DC-to-Philly-to-NYC corridor, a second storm later in the week may actually turn out to be a bit colder than expected. A cold air mass should be in place at mid-week with strong high pressure to the north holding it in place. The ultimate storm track for this next system will likely be quite different from this initial system with a possible re-development near the Mid-Atlantic coastline. As a result, the chance of accumulating snow at the onset of the next storm system has increased for the DC-to-Philly-to-NYC corridor in the late Wednesday night/early Thursday time frame. Any snow that does develop at the onset of the late week storm is likely to change to a wintry mix later in the day on Thursday and there certainly can be a buildup of ice in parts of the Mid-Atlantic region on top of the possible accumulated snow.  Stay tuned…something to monitor closely during the next few days.
