None of Monday’s tornadoes were spotted in Siouxland… The nine were between Des Moines and Iowa City.
While most of the twisters didn’t do any damage… one in central Iowa’s Hardin County appears to be the exception. It briefly touched ground in the city of Radcliffe and left a path of some destruction.
Trees were uprooted trees, power lines taken down, roofs damaged on buildings and vehicles overturned.
The brief twister was part of a small severe thunderstorm that moved through that area, pea sized hail was also reported.
The National Weather Service plans to send a team to survey the damage.
So how rare is this?
By the month.. we get the most tornadoes in June, 521 for the month since 1980. In November through the 35 year period from 1980 to 2015, we’ve gotten got 41 tornadoes. But nearly half of those occurred in one day!!!
November 15, 2015 ranks number 7 for most tornadoes in an individual day for the state. A strong line of storms pushed through Iowa, Missouri, and Illinois dropping 19 tornadoes ranging EF0 – EF2. Again, that’s half of our 41 for the 35 year period!
It goes to show while November tornadoes are rare, they are not impossible.
While Iowa is part of tornado alley and does have a “severe weather season,” most of our Iowa tornadoes are EF0 and EF1…the weakest in strength with winds up to 85 mph. We’ve have one catastrophic EF5 since 1980, a tornado packing winds over 200 mph.
