As Mat noted, "If you live anywhere from Philadelphia, through New York, New Jersey, and lower New England you don't need to be told how abnormal the snow over this past weekend was, or that it set records. But you may not be aware just how unusual it really was. For that, Jeff Masters at Weather Underground lays out the details. Masters describes the storm as 'simply unbelievable'."If you weren't there to experience it, this NASA image will help with the see-it-to-believe-it factor.
NASA writes, "An unseasonably early snowstorm dropped as much as 32 inches (81 centimeters) on some parts of the northeastern United States in late October 2011. The nor’easter left wet, heavy snow on trees that were still loaded with leaves. News reports described snapped branches and power lines, and utility companies were scrambling to restore lights and heat. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on October 30, 2011. A swath of snow sweeps from West Virginia to Maine. Clouds hover east and west of the snow, blocking the satellite sensor’s view of western Pennsylvania and parts of the Atlantic Ocean."
Here is another view:
NASA notes, "When NASA's Aqua satellite passed over the northeastern U.S. on November 2, 2011 at 2:00 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a detailed image of the remaining snowfall. Snow still covers the ground in western and central Connecticut, southeastern New York, western and central Massachusetts, and parts of Vermont, New Hampshire and Maine. Over the Atlantic, cirrocumulus clouds create a diagonal border."
