Monday night’s hail storm that hit Boulder and communities in the western and northern of part of the metro area before heading east produced baseball-sized stones reaching up to 3 inches in diameter.

These storms are not unusual for this time of the year, said Jim Kalina, a meteorologist at the National Weather Service Center in Boulder. He said the last week of May, along with the last two weeks of June usually bring severe weather to the Denver area.

“Usually by the end of June, it shifts east across the plains, but typically (this) time is when we see the highest probability of getting storms like this,” he said.

A storm hit the metro area in May of last year that was one of the most costly in recent Colorado history, with damages totaling $2.3 billion, according to the . As the Denver Metro area is in “Hail Alley,” it falls within the region “with the largest frequency of large hail in North America” according to insurance association.

No estimates on any damage from Monday’s storm have been made at this time.
