Many locations in the Midwest and Northeast doubled their season-to-date snowfall this week. Chicago piled up 19.3 inches of snow from January 31-February 2, making it the fifth largest snowstorm in Chicago's history. The largest snowstorm is 23.0 inches from the Big Snow of January 26-27, 1967. So far this week Chicago has measured 22.6 inches of new snow, and more fell today. The total for the season so far is 36.3 inches. The average for Chicago for the season is 38.0 inches.
Detroit, MI had been enjoying a fairly tame winter until this week as well. However, the big storm last weekend dumped 16.7 inches on Detroit with 18.4 inches in the last week. That brings their seasonal total to 35.8 inches. The average seasonal snowfall for Detroit is 44.1 inches.
Much of New England was just getting back to normal when the weekend storm brought more snow to the region. Boston picked up another 15.9 inches of snow, making it 42.5 inches for the week.
However, the most impressive and spectacular snowfalls occurred in Downeast Maine. Our CoCoRaHS observer at Eastport 1.5 SE (ME-WS-24) has measured 76.0 inches of snow since January 24! As of this morning the snow cover was 60.5 inches deep! This is far and away a record for a ten day period.

The highest percentage this season so far was on January 4 when 54.1 percent of the U.S. had snow cover. On November 17 snow cover was 50.1 percent as a result of the unusually cold and snowy period the middle of that month. Note that the largest difference on these maps is the lack of snow in the western U.S. this season. The chart below shows the daily percentage of the U.S. covered by snow since November 1.
