Discussion

Spring officially began yesterday afternoon, but the weather is simply not cooperating in the Mid-Atlantic region. A major coastal storm will produce significant snow accumulations today in the I-95 corridor all the way from DC-to-Boston with the Philly metro region likely in the 8-14 inch range. In addition to the snow, winds will intensify as low pressure off the Mid-Atlantic coastline strengthens and the combination of strong winds gusts and heavy snow raises the prospects for power outages. Winds can gust to 40 mph at inland locations during the brunt of the storm and to 50 mph at coastal sections of NJ. Later today, mesoscale snow bands may form which can produce 2-3 inches of snow per hour and some “thunder snow” is possible as well. As with many March snowstorms, elevation is likely to play a critical role with the difference of a couple degrees from lower spots potentially making a noticeable difference in total snowfall accumulations. The snow will wind down this evening, but the winds will stay strong right through the night.
