December 16th, 2009: Christmas Day Statistics (Brian Bledsoe)

Our good friends at the National Weather Service Office in Pueblo put these stats together, in reference to Christmas Day.  In case you were wondering about our annual chances for a white XMAS, here you go...

 

The chances are not very good if you are wishing for a "White Christmas" across much of Southeast Colorado. The most widely used definition of a "White Christmas" is 1 inch of snow on the ground on December 25th. After a very winter like feel for the first part of December and a mild mid December, the latest computer projections are indicating more unsettled weather possible for Christmas Eve and Christmas Day. Listed below are "Christmas facts" which have been compiled from the Pueblo, Colorado Springs and Alamosa climate records.

There was 1 inch of snow on the ground that Christmas morning, with an additional 0.6 inches falling that day. Over the past 108 years, there has only been two separate occasions where snow has fallen on two consecutive Christmas - 1911/1912, and in 1941/1942.

The last "White Christmas" was in 2007. There was 6 inches of snow on the ground at 5 am that morning. While no snow fell during the day, it began to fall around sunset with a total of 2 inches falling through the evening. The last time before that was in 1997 when there was six inches of snow on the ground at 5 am that morning, and a total of 1.1 inches falling for the day. The last time before that was in 1987 when there was 3 inches of snow on the ground that Christmas morning, with 2.4 inches falling that day. Over the past 55 years, snow has never fallen on two consecutive Christmas'.

Snowfall records are in inches, from 1952 to the present. Snow on the ground is at 5 am MST

(7 am MST from 1984 - 1991 due to part-time staffing).

 

So, while the chances of a White Christmas aren't very good, we are going to see some weather changes occur next week.  There is still much uncertainty with how it will evolve, but a storm system could potentially bring snow to the area next Wednesday and Thursday.  Tough to say how much at this point, but it could potentially bring us some snow.  In addition to the snow chance, much colder temperatures will arrive next Wednesday.  Either way, it does look like it will feel more like Winter as we get into the middle of next week.  We'll keep you posted...
