Midwest’s April chill most unusual on Earth

If you thought the cold April weather in the U.S. was exceptional, you are correct.

In terms of temperature departures from average so far this April, the U.S. Midwest, Northern Plains, and much of Canada have been the coldest on Earth (graphic courtesy of Weatherbell.com):

Surface temperature departures from normal for April 1 through April 15, 2018.

The areas of green have averaged at least 6 deg. F below normal, the areas in purple have been at least 13 deg. F below normal, and spots in North Dakota and Montana have averaged close to 20 deg F below normal over the last 2 weeks. In contrast, the global average temperature has been running 0.5 deg. F above the 1981-2010 average.

Snow flurries were experienced as far south as Russellville, Alabama yesterday, and flurries are still falling in portions of Tennessee. Green Bay, WI received 2 feet of new snow from the slow-moving snow and ice storm still affecting the Great Lakes region. Northern Michigan is still experiencing heavy snow, with whiteout conditions this morning at the Mackinac Bridge, which connects Michigan’s Upper and Lower Peninsulas:
