Meteorologists say warmer weather has brought unusual November weather to Iowa and Nebraska: tornadoes.

The National Weather Service says as many as four tornadoes were reported Monday afternoon in central and northeast Iowa, while three were spotted Sunday in south-central Nebraska. The storms caused light damage and no injuries in both states.

Rich Thompson with the Storm Prediction Center said Tuesday that it's rare for tornadoes to form so far north and west in late fall. He says warmer weather allowed the typical storm track to move north.

National Weather Service statistics show that only seven tornadoes have hit Nebraska in November since 1950. In Iowa, 41 tornadoes were reported in November between 1980 and 2015.
