Denver officially set a new record high temperature for March 2nd.

Updated, 5:30pm:  Denver’s official high temperature today reached 74 degrees at 3:08pm, beating the old record of 72 degrees by two.

Original post, 2:39pm:  Denver has officially broken the high temperature record for today, March 2nd.  At 1:52pm the thermometer at Denver International Airport reached 73 degrees, besting the old record of 72 degrees set way back in 1901.  Here in Thornton we were a touch warmer reaching a high of 74.1 degrees.

This afternoon there is a chance the temperature could go a degree or two higher thus further increasing the record.

Is this really a record?  Since moving Denver’s official weather recording station to DIA, many weather enthusiasts believe our weather and climate records are being unduly altered.  Examiner.com just launched an investigative feature into this problem today – check out part 1 of our series on Examiner.com:  Do Denver weather and climate records have an asterisk attached?

Denver and Thornton’s March 2009 climatological preview

Denver and Thornton's March 2009 climatological preview

March in Denver typically means frequent and rapid weather changes. The days grow longer and we start enjoying more sunshine and sometimes summer-like weather. However, on occasion arctic air masses can still force their way south into Colorado dropping temperatures quickly and markedly.

These changes are due to Marches “in between” status – elements during the month have much in common with winter and spring. In addition to arctic fronts, Pacific storms frequently move across Colorado from the west and warm moist air streams up from the Gulf of Mexico northeastward into the state. When these cold fronts collide with the warmer air masses the result can be some crazy weather.

Dreaming of a white Christmas? The chances are slim

What are the odds of a white Denver Christmas?  Not very good.
What are the odds of a white Denver Christmas? Not very good.

As Christmas gets closer everyone always wonders if we are going to get the proverbial white Christmas. Unfortunately, if you look at Denver and Thornton weather history, the chances arent all that good but it also depends on what you define as a white Christmas. December just isnt that snowy of a month, ranking as only the fourth snowiest (behind March, November and April) so historically we have a bit of a disadvantage.
