Webcams from astronomical observatories located high up in the mountains seemed to confirm this, too. But as excitement grew over the possibility of a perfect ‘50-for-50’ event in mid-February 2010, forecasters in Hawaii were pessimistic, saying it had been several weeks since there had been snow in the mountains and that none was expected to fall any time soon. While snow in Alaska is to be expected during February, it’s also surprisingly common in the highest elevations of Hawaii’s mountains throughout much of the year.

The inset images show pockets of snow on Hawaii’s 13,800-foot Mauna Kea volcano, taken on February 12, 2010. Snowy summits can be seen in the Cascades and Sierra Nevadas, as well as other mountain ranges throughout the Northwest and Southwest.

Snow blankets the majority of the Lower 48, almost entirely covering the Northeast, Midwest, and northernmost states of the Great Plains.

The last time was five years ago this coming Thursday. But when was the last time there was snow on the ground in all fifty states-even our most tropical destinations, Florida and Hawaii? This kind of scenario is pretty rare and sometimes tough to document, but it has happened. Thanks to back-to-back storms over the last month, most of the Midwest and North-Atlantic regions are covered by snow.
