This is a quick post to show you just how rapidly the snow cover has expanded this month over the United States. November has been a cold month for most regions in the U.S. and could even rival some of the coldest Novembers on record if we don’t have any huge moderations in temperatures by the end of the month. With parts of the Southern Plains getting decent snowfall accumulations yesterday and then areas of the Ohio Valley getting accumulations yesterday and last night, we currently have 50.4% of the United States covered in snow.
That is compared to just 11.0% snow cover last week.
What even becomes more impressive is how quickly the snow cover has expanded over the United States over the last couple of weeks. Ending the month of October, we only had 1.1% snow cover across the U.S., and comparing that to previous Octobers, that is quite low.
To give you an idea of how this compares to this time last year, about 12.5% of the U.S. was covered in snow. To put all of this in even better perspective, the U.S. typically has about 33% snow cover around Christmas. Amazingly, we currently have much more than that.
With another Arctic outbreak pushing into the U.S. this week, the snow will not melt much for most areas to start off. In fact, the snow cover on the ground will likely cause this Arctic blast to be even more potent. Records will definitely be challenged or broken for many areas across the U.S.
Below I included a photo that I shared on Instagram earlier that was sent to us by Dale Johnson Moss in Calhoun, GA. This was actually last winter, but I figured it’d get you in the winter mood. Be sure to follow Firsthand Weather on Facebook, Twitter, and Instagram. I post updates on social media often.
Matthew Holliday is a graduate of the University of Oklahoma, where he completed a B.S. in Meteorology and a B.S. in Geographic Information Science. He is currently pursing his master's degree in meteorology and climatology at Mississippi State University. Matthew founded Firsthand Weather in 2010 as a senior in high school and maintained the site through his undergraduate career. Research that was conducted by Matthew while at OU involved determining the synoptic environment in which various types of wave clouds (including vertically propagating waves and trapped waves) develop in Boulder, Colorado and Norman, OK. Matthew also did research on spatial changes in tornado activity across the United States . The goal of this study was to determine if spatial changes in tornado activity had occurred and if those changes could be linked to changes in average surface dew point temperature. Matthew has completed coursework in dynamics, thermodynamics, cloud physics, calculus and differential equations, statistics, remote sensing, GIS, synoptic meteorology, and mesoscale meteorology. His goal is to provide his audience with a deeper understanding of what drives our weather and climate, while making it easy and enjoyable to learn.
