The above image is two satellite images of the northeast. The top photo was taken the day after the blizzard of 2016. Notice the large extent of the snowcover. The bottom photo taken about a week later on February 1st, shows the dramatic melt that occurred in just one week. This was due to above average temperatures from the infamous January thaw!
Here's a table showing how fast the snow melted in Central Park. The table was released by the National Weather Service New York City office. It also shows the temperature departure for each day. In just four days, Central Park went from almost two feet of snow to just six inches!
