From The Denver Post (Chris Bianchi):
We’ve made a big deal about these statistics, and snowpack is unquestionably far higher than where it normally is for the beginning of June. But, these numbers – while true, of course – might be a bit misleading and worth an extra note of clarification. On Friday, the Colorado Climate Center sent a series of tweets to help explain the significance behind some of the snowpack data figures that have garnered so much attention.
So essentially, it’s the slow start to the melting season – fueled by cold late spring temperatures and, yes, some bouts of late May snow – that’s keeping Colorado’s snowpack so ridiculously high.
