The National Weather Service has issued Winter Weather Advisories, and even put one Virginia area under a Winter Storm Warning, for a light snow event expected to unfold later tonight into early tomorrow morning.
A cold front pushing through the northeast will help set the stage for this light snow event. This cold front will move farther offshore tonight, but a wave of low pressure will develop along it and move through the offshore waters. Unlike previous storms this winter where storms were potent and amplified, this system will remain rather weak and progressive. A shield of light precipitation will develop in the Mid Atlantic as the system blossoms and quickly moves away.
While snow showers and flurries are expected to fly over a broad area stretching from West Virginia to southeastern New England, accumulations will be minimal at best in most locations. Up to 1-2″, and perhaps 3″, will be possible over portions of Long Island, southeastern New England, southern New Jersey, northern Maryland, southeastern Pennsylvania, western Virginia and eastern West Virginia. In the Winter Storm Warning area over Augusta County in Virginia, including the Central Blue Ridge area, 3-4″ is expected to fall with the risk of an isolated 8″ amount on the highest mountain peak in the area.
Snow showers will quickly wrap up by Sunday late morning and early afternoon, with fair and dry conditions returning to the region. Sunday night will be a cold one with a fairly strong cold advection pattern setting up in the wake of the low pressure system over the area.
For Monday, conditions remain brisk under mostly sunny skies with high pressure gradually building in just west of the region. Temperatures in the areas seeing snow tonight and tomorrow morning will not likely get out of the 20’s for a high temperature reading on Monday afternoon.
