November snowfall records tumble; arctic air mass follows (Examiner, Nov 11, 2014):

Yesterday morning, it looked as though heavy snow was going to affect parts of south-central Minnesota. That snow came with a vengeance, especially to the northwest of the Minneapolis, MN area and then northeastward to the Upper Peninsula (UP) of Michigan. St. Cloud, MN broke a daily snowfall record, as well as a 24-hour November snowfall record with 13.2 inches of snow on Nov. 10, 2014 (Fig. 1). The old daily snowfall record was set in 1946 (4.3 inches); the old 24-hour November snowfall record was 12.0 inches set in 1898.

Due to the magnitude of yesterday’s snowfall, melted precipitation (the amount of liquid water in the snow) measured 1.24 inches at St. Cloud, MN. This broke the record daily liquid precipitation record for the day (0.67 inches set in 1998). Other records likely fell, but were not yet reported through the evening hours of Nov. 11, 2014.

Here are some of the other larger storm totals (in tenths of inches) for Minnesota, Wisconsin and the UP of Michigan (through midday Tues., Nov. 11, 2014). All values are for observation times on Nov. 11 unless otherwise noted. Data were obtained from National Weather Service web sites in the areas affected by the heavy snow.

This storm system is exiting the U.S. this afternoon and will be a distant memory, quickly. However, in its wake, bitterly cold arctic air is spreading across most of the eastern U.S. By Thursday, only the southeast (Florida, south Georgia and parts of the Gulf Coast) will escape its wrath. However, all but central and south Florida will see some cooling of temperatures.

Parts of Texas and Oklahoma are now under freeze and hard freeze watches, warnings and advisories for sub-freezing temperature conditions tonight and for the next several nights.

This is in stark contrast to record highs that were set yesterday (Nov. 10) in places like Childress, TX (87; old 85 in 2012); Borger, TX (85; old 80 in 2007) and Dalhart, TX (84; old 79 in 1980).

Cold air will also invade the eastern Great Lakes where mid-60 degree readings today will yield to bitterly cold winds and lake effect snow showers tomorrow into Friday.
