Colorado weather: Is late-season snow more common on Front Range?
Denver has seen later-than-average snowfall for the sixth time in the last 7 years
If you like sunshine and warm weather, you’re probably not going to like next week’s forecast.
Rain and cooler temperatures are likely, and even snow could once again be in the forecast, just a few days after a slushy inch of snow fell on April 29. Even if doesn’t snow next week, though, Denver has already clinched the dubious honor of finishing with a later-than-average snowfall for the sixth time in the last seven years.
Ironically, as temperatures have warmed and the climate has dried, particularly since 2000, the Front Range has seen an uptick in late-season snowfalls. Since 2000, Denver’s average last measurable snowfall date has gone back to May 1 — while the 1882 through 2019 average is April 27. A few days may not sound like a whole lot, but in an overall warming climate, it’s a strange anomaly that has other unusual implications.
