Today is the last day of very chilly temps after I think three weekends being impacted by anomalous cold weather. Conditions have been superb all over for weeks but the weekenders have had a rough go of it. Thing are going to change starting Tuesday but it's far from a torch, in fact the entire region will sill average below normal temperatures this week but there will be some very limited melting in warmer areas.
We have one sleeper storm coming in on Tuesday that should give parts of NY and New England a healthy dose of snow on the taller mountains, though spread across two days. Then on Sunday we have an opportunity for another storm. Here's what the GFS sees presently for this week.

I'm going to break this weekly outlook down into a Temperature Outlook, then a Tuesday-Wednesday Storm Preview, and then a Sunday-Monday Storm Watch.
