Discussion
The threat for an all-out major snowstorm is on the table from Philly to Boston and it is not out of the question that there will be significant snow accumulation late tonight/early Thursday in the far northern and northeastern sections of the DC metro region. The weather pattern will be very active over the next 36 hours ranging from warmth today to accumulating snow. It’ll be quite warm today in the Mid-Atlantic region ahead of a strong cold frontal system and there may be a few showers 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. During the changeover period from rain to snow there can be some sleet involved. By early tomorrow, intensifying low pressure will be just off the Mid-Atlantic coastline and the snow could fall quite hard across the northern and northeastern suburbs. Accumulations on the order of a coating to a couple of inches are likely from the District to points south and west and could range from 2-4 inches in the far northern and northeastern sections of the DC metro region. This storm will then head all the way up along the coastline dumping accumulating snow on eastern New England.
