I hope Nathan is doing okay (with his bee sting), if that didn't put him out of action, there has been a major wedge tornado moving across the northeast corner of Missouri past two hours, severe damage (possible casualties) reported in Kirksville, and this storm continues east, now crossing the Mississippi River just about where Iowa, Missouri and Illinois meet (5 miles north of Quincy, IL). It would be around sunset in that part of the country at present time. Dangerous outlook tonight for northern IL as rain-wrapped tornadoes developing. Upper support suggests long lived outbreak tonight.
