A tornado watch is in effect for most Colorado counties south of Interstate 70 and east of the Interstate 25 corridor, according to the National Weather Service.

Colorado’s Eastern Plains can expect a few storms with hail over the next few hours. The National Weather Service Office in Boulder had issued severe thunderstorm watches and warnings for much of the state’s Eastern Plains.
