mckitterick | Weather-Porn of the Day: "Chiclone" over the Midwest (Reply)

Wow, this is amazing. The massive storm that caused the huge storms all across the country earlier this week set a new record for low pressure in a non-tropical storm in the continental U.S. with a minimum central pressure of 28.24" or 956 mb, the equivalent of a Category 3 hurricane. Extratropical storms like this one occur in the spring and fall when the temperature differential between the north of the country and the south of the country is greater. This week's storm produced 24 tornado reports, severe thunderstorms, blizzard conditions, hundreds of thousands of power outages, and winds that reached 77 mph.
