[1] This storm began as a classic "Alberta clipper", starting out in Canada and then moving southeast, and finally curving northeast while rapidly intensifying off the New Jersey coast, forming an eye.

"[citation needed] This storm appeared similar to the North American blizzard of 2005 because it redeveloped off the Atlantic coast and intensified into a powerful nor'easter.

The storm affected some of the same areas that already received historic snow totals during the February 5–6, 2010 North American blizzard, slowing cleanup.

The snow caused the cancellation of most flights into and out of Bradley International Airport, and Metro North operated trains on a reduced schedule on February 10.

As warmer air moved in aloft, the snow changed to sleet and freezing rain between 3 a.m. and 6 a.m. EST on the 10th.

[14] In Clearfield County, two pileups involving about 25 vehicles on snowy Interstate 80 left at least one man dead and 18 people injured.

[15] Snowfall totals in the Pittsburgh area generally ranged between 5 and 9 inches, but high winds created near-blizzard conditions during the morning hours of February 10.

The new accumulations coupled with blowing and drifting snow exacerbated major problems created by the February 5–6, 2010 North American blizzard.

[citation needed] Near Williamsburg, Virginia, whiteout conditions around 9:00 am EST, February 10, led to a fifty-car pileup on a stretch of westbound I-64.
