Midwest storm by the numbers
* More showers and storms today: Full Forecast *
Although the massive Midwest storm has peaked in intensity and jogged into western Ontario, its effects are still being felt across a large chunk of the U.S. Winds are howling in upper Midwest and Great Lakes, wind-whipped snow is flying in the Dakotas, and the cold front ahead of the storm is producing showers and thunderstorms up and down the Eastern seaboard. A few severe thunderstorms could still develop this afternoon in the eastern mid-Atlantic (including the eastern portion of the D.C. metro region) and Southeast.
But today will be nothing like yesterday, when this monstrous storm made history. Let's take a look at some amazing numbers associated with this storm:
956 mb or 28.24" - Record low pressure from non-tropical storm in continental U.S.
The National Weather Service writes:
... [the storm] had a minimum central pressure of 28.24" 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 Superstrom (aka "The Storm of the Century"), or the "Witch of November" storm that sank the Edmund Fitzgerald in 1975, or even the Columbus Day Storm of Oct. 1962.
St. Paul Tribune meteorologist Paul Douglas wrote the pressure may have even dipped as low as 953 mb (28.14") in Orr - a town in Minnesota's arrowhead. The barometric pressure dropped to 28.99" in Chicago - the lowest reading on record during October.

8" - Snow report in Harvey, ND accompanied by sustained winds near 40 mph and gusts over 50 mph
150-180 mph winds estimated at jet stream level driven by the large temperature contrast between the eastern and western U.S. - which in turn - fueled this storm in the center of the country.
