A drop in temperature by 60 degrees in just a few days may be damaging to perennials, shrubs and trees. There isn’t a thing we can do about the cold front that came through the Front Range this past week, but there are some things we can do to minimize the potential plant damage.
A blast of cold air from the north was pushing through Northern Colorado on Monday, causing temperatures to drop 20 degrees over the course of an hour. The bitter cold is supposed to stick around the state for the next week, with high temperatures staying below freezing through the weekend.
It's been a dry October, but the outlook for Colorado winter precipitation mostly sits right around normal. That's the projection made by National Oceanic and Atmospheric Administration scientist Klaus Wolter for the 2014-2015 winter season.
"Near-normal seems to be the keyword," he said. "With maybe a small tip of the hat towards a bit drier than normal."
After the extreme rains of 2013 hit Colorado, scientists wanted to know if the intense weather event was linked to climate change. After a year's worth of research, they have concluded that the unusual rain event was not made more likely or worsened by human-caused climate change.
