A stalled atmospheric set-up has made Boston and surrounding areas in the Northeast the most popular truck stop for storms travelling the atmospheric highway known as the jet stream. And stop they have, like a caravan of tractor-trailers idling in a rest stop parking lot.
Thanks to back-to-back storms over the last month, most of the Midwest and North-Atlantic regions are covered by snow. But when was the last time there was snow on the ground in all fifty states—even our most tropical destinations, Florida and Hawaii?
A major winter storm was still blustering its way through the U.S. Northeast this morning, with continued snow accumulations and high winds predicted for many areas. How will this event compare to the region’s most historic storms?
Just for fun, we asked the experts at the Rutgers Snow Lab to show us what their data (based on NOAA satellite images) had to say about whether the number of snow-covered days during the week of Christmas has changed at all across the U.S. in the past 50 years.
In June 2012, snow cover extent over Eurasia and North America hit a new record low. It is the third time in five years that North America has set a new record low, and the fifth year in a row that Eurasia has. The rate of snow cover loss over Northern Hemisphere land areas in June between 1979 and 2012 is -17.6% per decade—a faster decline than September sea ice loss over the same period.
