Vernal Equinox is today. So how COLD was this winter?

The Vernal Equinox is at 12:57PM Eastern Daylight Time.  Astronomical winter is over!

While the meteorological winter is far from following in the footsteps of the earth's tilt and position around the sun, it gives us a good time to look back at the official season of winter to determine how COLD it actually was versus other winter similar to it.

Back in February, I mentioned 4 indicators of winter severity 1) TOTAL SNOWFALL, 2) DAYS WITH SNOW ON THE GROUND 3) AVERAGE TEMPERATURE & 4) NIGHTS BELOW 10 DEGREES.  Was this winter among the coldest and snowiest all-time? Where did this winter rank?

Each graph will show where this year resides ALL-TIME which goes back to 1871. Many have mentioned how this winter is the coldest in a generation. So I created a second graph which shows the the information over the last 40 winters (since 1975) for a more recent perspective.


SNOWFALL
RANKS 9th ALL-TIME
 77.0"
  
LAST 40 WINTERS
4 WINTERS IN THE EARLY 2000s HAD MORE SNOW THAN THIS WINTER!





DAYS/SNOW ON GROUND MORE THAN 1"
RANKS 5th ALL-TIME
 79 DAYS


THIS WINTER IS TIED WITH 2010-11 AND 2002-03 FOR DAYS WITH SNOW COVER GREATER THAN 1 INCH:  





NIGHTS BELOW 10 DEGREES
RANKS 11th ALL-TIME
26 NIGHTS



THE LAST WINTER WITH MORE NIGHTS BELOW 10 DEGREES WAS WINTER 1978-79



AVERAGE TEMPERATURE
RANKS 20th ALL-TIME
COLDEST SINCE 1993-94
5TH COLDEST IN THE LAST 40 WINTERS
