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 some accumulating snow to the area on Thursday night which could end early Friday as light rain or freezing rain - possibly impacting the AM Friday commute. 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 and this could cause "flash freeze" conditions with a possible quick ice-up. Single digits are possible by early Monday morning - the coldest air mass so far.
