Discussion
The threat for a major snowstorm has increased for the region from Philly to Boston and accumulating snow is likely all the way down to the DC metro region late tonight and on Thursday. The overall weather pattern will be very active over the next 36 hours ranging from today's warmth to significant accumulating snow. It’ll be well above normal today in the entire Mid-Atlantic region ahead of a strong cold frontal system and there may be a shower or two to go along with the warmth. Colder air will then push into the region this evening at the same time low pressure rapidly develops in the eastern US. Rain is likely for awhile tonight, but then as colder air moves in, a changeover to snow will take place towards morning from northwest-to-southeast. There will likely be some sleet involved during the changeover period of rain-to-snow. By early tomorrow, intensifying low pressure will be just off the Mid-Atlantic coastline and the snow will likely fall heavily at times. When all is said and done, this is likely to be the heaviest snowfall this season in many areas along the I-95 corridor with 5-10 inches on the table for the Philly metro region. This storm will head all the way up along the coastline dumping accumulating snow on eastern New England as well. One final note, the snow will likely be of the heavy, wet variety and can cling to trees and bushes raising the possibility of downed limbs and power outages.
