2013-14 Season is Snowiest on Record at Detroit and Flint

SNOW

After a late-season snowfall, the 2013-14 season is officially the snowiest on record at both Detroit and Flint. We have already discussed the record January snowfall in Detroit and Flint as well as the snowiest starts to the winter season through January.  February finished as another top 20 snowiest month with Detroit at its 9th snowiest February, Flint 3rd snowiest and Saginaw T-15th snowiest February on record.  All of this snow is placing southeast Michigan into the top of the seasonal snowfall records.  The past 10 to 15 years have had some active and snowy winters.  In fact, this winter puts 6 of the last 14 years into the top 20 snowiest winters on record

Most Consecutive Days with Snow Cover (1 inch or greater)

Not only have we received a lot of snow this winter, but the lack of thaws has allowed the snow pack to be remarkably long-lived.  We have set records at both Detroit and Flint for consecutive days with snow cover.  The snow cover streak began on 12/31/13 at Detroit, and on 12/9/13 at Flint, before ending in mid-March.  The table below shows the longest streaks of consecutive days with at least 1" snow depth (ending date in parentheses).

Cold-Season Temperature Stats

November and especially March are more like winter months in Michigan.  Another way to look at the prolonged very cold regime over the Great Lakes is to look at the average temperature from November 1st to the end of March (the cold season).  The 2013-14 cold season was a record-setting one at Flint: the average temperature of 24.0 beat the previous record low of 24.5 set back in 1962-63.  This cold season was the second-coldest of all time at Saginaw and the fourth-coldest at Detroit.

Below-Zero Days        

This winter has also experienced a number of low temperatures below zero.  Below is another table to gain additional perspective on the cold by looking at the number of times we have fallen below zero this cold season.

Below Freezing Days          

Not too surprising that winter is also approaching another "Top Ten"...the most number of days freezing or below (32 degrees or lower for a high temperature).  Below is a table to see where the 2013-14 cold season ranks in this metric.
