Mid-Winter Snowfall Review: East Coast 80% Above Average

As of January 29 (Saturday), meteorological winter was 2/3 over (30 days remaining until March 1). The seasonal snowfall amounts to date from the major East Coast National Weather Service reporting locations show that overall snowfall has been 83% above average across the region.

The top chart shows the total snowfall this season through January 29 (blue bars) compared to the climatological normal (green bars) for 26 stations from Caribou, Maine through Raleigh, North Carolina. The stations are arranged roughly from north to south. With the exception of the lake-effect snowfall at Syracuse (SYR), the greatest amounts relative to normal have been at near-coastal locations from southern New England through the Mid Atlantic. In fact, Caribou, Maine (CAR), the most northerly location, has a deficit of over 20" (second chart). The area with the most excess of snow ranges from Boston (BOS) to Philadelphia (PHL). Note that the interior location of Scranton (AVP) is the only other one besides Caribou with below-average snowfall.
