Discussion
A cold front will pass through the region tomorrow night and usher in colder air for Thursday which will feature increasing clouds ahead of the next low pressure system. This next low pressure is likely to bring rain, ice and/or snow to the area on Thursday night with small accumulations possible. A strong cold front will arrive in the eastern US this weekend and a significant storm will develop along its boundary zone. The result is likely to be lots of rain, ice and/or snow for much of the Northeast US, but it is too early to tell how much of each will fall in the DC-to-Philly-to-NYC corridor. Snow and ice will be more likely across interior, higher elevation locations and rain will be more likely along coastal sections. On the back side of the storm, bitter cold Arctic air will flood the Mid-Atlantic region late Sunday into Monday - the coldest air so far - and this could cause "flash freeze" conditions with a possible quick ice-up.
