From the KBTX Weather Blog:
Thursday night snow was falling here in Bryan/College Station, piling up in Dallas/Ft. Worth to what would amount to be 12.5", and spreading east towards other parts of the United States. By Friday night, that same system even put a dusting of snow on the ground in the Florida Panhandle! That got us weather folk wondering, could there have been snow in all 50 states at the same time? After scientists in Hawaii scoured the mountain tops, it seemed as if they were the only state holding out meaning, only 49 of the 50 had snow on the ground.
Until this happened....
A graduate student out of University of Oklahoma named Patrick Marsh confirmed the milestone in his blog with this picture. Two tiny specs of snow atop Mauna Kea in Hawaii on February 13.
