Deepest Non-Tropical Low Ever Measured on the U.S. Mainland!

A new record was set today for the lowest pressure in a non-tropical storm in the mainland United States. The massive storm system barreling across the central U.S. had a minimum central pressure of 28.23" or 956 mb (equivalent to the minimum pressure of a Category 3 hurricane). This breaks the old record of 28.28" (958 mb), set on Jan. 26, 1978, during the Blizzard of 1978 (aka the Cleveland Superbomb). This is also lower than the March 1993 Superstorm (aka "The Storm of the Century"), and the "Witch of November" storm that sank the Edmund Fitzgerald in 1975, and even the Columbus Day Storm across the Pacific Northwest in October 1962.
