Discussion
A couple of low pressure systems will merge just off the Mid-Atlantic coastline by early tonight and snow will develop here during the late afternoon hours and continue into the evening. Accumulations of an inch or so are likely and slick road conditions will develop quickly given the extreme cold ground conditions. Salt loses some effectiveness on the roads when the air temperature is below 20 degrees and that is likely to be the case during most of this event. This snow event, while not at all heavy, will be rather widespread some small accumulations up and down the I-95 corridor from DC to NYC and east to the Jersey coastline. More cold air will follow for the upcoming weekend; however, moderation in temperatures is likely early next week. That transition on Monday between the weekend cold and the early week moderation will be difficult at first and the result could be some frozen precipitation on Monday in the form of light snow, sleet, and/or freezing rain before it gets mild enough for some plain rain. Tuesday and Wednesday promise to be much milder here with temperatures not far from 50 degrees by mid-week, but colder air moves back into the region by Thursday of next week.
