DENVER — Tuesday afternoon storms are expected to roll across the Front Range bringing pockets of isolated heavy rain with strong to severe storms possible on Colorado's plains.

The National Weather Service (NWS) in Boulder issued a flash flood watch for areas surrounding Denver.

“Denver will see some scattered storms this afternoon and there is going to be a risk of severe weather on the eastern plains,” said Denver7 Meteorologist Lisa Hidalgo. "We’ll see more widely-scattered storms in the mountains by the afternoon and those storms will gradually push east. Some of these storms could produce some larger hail and damaging winds.”

The Denver7 news team is tracking the latest Colorado severe weather alerts and conditions across the metro.
