"Temperatures in all 50 U.S. states dipped to freezing or below on Tuesday as an unseasonably cold blast of weather moved across the country, while heavy snow prompted a state of emergency in western New York.

In the U.S. South, states were bracing for a record chill from the Arctic-born cold that swept the Rocky Mountains last week.

Every U.S. state, including Hawaii, was bitten by temperatures at the freezing point of 32 degrees F (0 C) or below, the National Weather Service said.

Hawaii's Mauna Kea, a dormant volcano, had low temperatures of 30 F (-1 C) to 32 F, said NWS spokeswoman Susan Buchanan."

So in Hawaii it was just at the tippy top of an old volcano. But that still counts right!!!!1
