Snow in all 50 states on Feb 12.


February 12 marked a very rare event in the US as all 50 states documented having snow on the ground at the same time. The latest winter storm to push across the southern portion of the US brought up to 20 inches of snow from Texas eastward to South Carolina. Hawaii was the last state to report evidence of snow on the ground, and it wasnt much, but a few patches of snow remained on a steep north facing slope of Mauna Kea, the highest mountain peak in the state.  Thie snow was left from an event back in November, but will likely be gone within the next few days. 

It is not clear if this has ever happened before in the US, though it likely has.  Detailed snowfall records for many areas only go back around 30 years. According to the Associated Press, The Global Snow Lab at Rutgers University is researching to find if this has ever happened before.

The map below depicts the snow depths across the contiguous US as of today, February 13. The total ground coverage with snow amounts to 67.1%. Alaska, though not shown, does have significant snow depths across the state as well.
