The snowstorm of December 20-21 2010 was probably the most surprising snowstorm we have had in a long time out here on the Cape. It was so surprising because there wasn't even one weather headline posted that morning of the 20th before a Winter Weather Advisory was posted around 3pm EDT that afternoon, then around 6pm EDT a Winter Storm Warning was issued for 6-10", then the updated warning issued was for 6-12" across the Cape and Islands. We ended with 11.0" for storm total out here in Harwich, MA. Then the great Boxing Day Blizzard struck New York City, NY no less than 6 days afterwards, we ended up with 1.0" of snow from that storm. The 20th of December was amazing, it snowed the whole day, but not nearly hard enough to accumulate given the rather warm surface temperatures, but once nighttime rolled in so did the heavy band of white roll on through the region. It was an amazing sight. Throughout the morning hours it looked like the ultimate screw job was taking place, until the ocean storm sent the band westward after 12pm EDT. It was like a complete whiteout for several hours at least and accumulated quickly once sun set. It was truly a winter wonderland.
