Thunderstorms, Tornado Watch On Tap For Northern Colorado

June 27, 2016

Thunderstorms Monday afternoon over Denver and eastern Colorado could bring strong winds, heavy rain, and hail.

The National Weather Service in Boulder also issued a tornado watch for north-central and northeastern Colorado until 8 p.m. 

The hail could be an inch in diameter or more. Colorado gets more hail than many other states because of its cooler latitude, high elevation and frequent thunderstorms. 

Bob Koopminers, meteorologist for the National Weather Service in Boulder, explains hailstones get bigger the longer they stay aloft.

"A strong updraft in a thunderstorm will keep a piece of frozen material suspended longer," Koopminers said. "As the thing goes up and down in the thunderstorm, the liquid water sticks to it and the stone grows."

The Denver area could see a repeat of this afternoon’s stormy weather Tuesday through Thursday.
