Thunderstorms Likely Again, Some Will Be Severe

Castle Rock and surrounding areas dodged the bullet with severe weather yesterday, only receiving small hail and ample amounts of rain and wind. Luckily no reports of hail damage in our area and no tornadoes, with the exception of a funnel cloud in Eastern Elbert County.

As expected, yesterday’s main threat was large damaging hail.

We did receive several reports of hail between 1.5 and 2.5 inches in diameter that caused extensive damage in Wheat Ridge, Lakewood and Northwestern sections of Denver.
