The giant storm currently wrecking havoc across the Midwest has a low pressure (957mb per 18z Surface Analysis from NOAA’s Hydrometeorological Prediction Center) equivalent to a category 3 hurricane. To be clear, that is historically low for the Midwest.

CIMSS notes that the storm is still deepening. At least the winds of this storm aren’t on par with those of a major hurricane, unless you count the nearly 200 reports of severe winds/damage so far today (blue dots on map to right). But even the strongest severe thunderstorm winds rarely make it much into category 1 hurricane territory. (Winds over 58mph are severe, winds over 74mph are hurricane, winds over 114mph are category 3 hurricane.)
