COLORADO, USA — Late April blizzards are extremely rare in northeast Colorado. Since 1996, there have only been two blizzards after April 15, and neither one of those hit the I-25 metro corridor. They were both on the eastern plains, one on April 22, 2001, and the other on May 2, 2008.
But, that does prove that blizzards are possible all the way into May. Two years ago, in 2017, a blizzard hit Prowers and Baca Counties in southeast Colorado on May 3.
At this point, the computer forecast models are not showing any signs of blizzards all the way through May 1. The highest potential is the next storm, which is hinting at a snow a wind combo this Thursday in parts of east and southeast Colorado.
As for accumulating snow, that is a different story. The Denver metro has had measurable snow all the way into May, four of the last ten years -- the last time being 2015.
For whatever reason, Mother's Day seems to be a common final target for snow. The 2015 storm was Mother's Day. During that storm, more than six inches fell in the suburbs and four inches at DIA.
In 2014, it was Mothers Day again with one to four inches in the metro. In 2011, and 2010, the final snow was just a couple days before Mother's Day.
This years Mother's Day is May 12, which is still too far out of the range of any reliable computer models.
