A Cold Start to February

After a generally mild end to January across much of south central and southeast Colorado, two successive arctic air intrusions blasting across the Rockies during the first ten days of February, has helped to make the start of February 2011, one of the top 10 coldest on record. Below are temperature records for Colorado Springs, Pueblo and Alamosa for the first 10 days of February, including preliminary data for 2011.
