Discussion
An Arctic blast arrives later today with possible snow showers and perhaps even a heavier snow squall. Temperatures on Wednesday will have a hard time reaching the 30 degree mark in the DC-to-Philly-to-NYC corridor and strong NW wind gusts to 40 mph will generate considerably lower wind chill values. Low pressure will form in the Ohio Valley later Wednesday as the next in a series of upper-level energy features drop southeastward in the very active northern branch of the jet stream. Snow from this low pressure system is likely to push into our region late tomorrow night and continue into early Thursday. There can be some road problems during the Thursday AM commute caused by very cold conditions and potential snow accumulations. More upper-level energy in the northern branch of the jet stream will try to consolidate near the Mid-Atlantic coastline late in the week and, if successful, there could be more snow around here by Friday night or Saturday.
