In Ohio this week an eerie weather phenomenon caused many folks to do a double take rare snow rollers made their way across yards unaided.
Snow Rollers occur under specific conditions, according to the National Weather Service (NWS): “The ground surface must have an icy, crusty snow, on which falling snow cannot stick. About an inch or so of loose, wet snow must accumulate. Gusty and strong winds are needed to scoop out chunks of snow,” says the agency.
These snow tumblers are formed by gravity or wind, in Ohio, they were rolled around by the gusting winds after a sheet of ice was covered with a blanket of snow. This phenomena looks much like a carpet lightly rolled up 'snowman style' and the inside of the roll is hollow not solid.
Since the New Year there has been no shortage of mysterious phenomena from light and fluffy snow rollers to fireball alerts on a crisp winters night.
