BlizzardNole Posted August 29 Share Posted August 29 Whew! That cell scared me when it peaked with purple echoes on Radarscope but weakened just in time. Got some marble-sized hail, rain and lightning. I've seen baseball-sized hail twice and never want to again The second time was $1500 damage to my car and that was 1992 so like 4 or 5 thousand today 2 1 Link to comment Share on other sites More sharing options...

Mrs.J Posted August 29 Share Posted August 29 I am under that warning over here. But the main part of the storm slipped literally to my East. The thunder is loud though with a lot of lightning. Mr. Jones is trying to get home from MoCo on 28 because 270 is just getting hammered from Germantown all the way up to Frederick. The younger Ms. J who is up at school in Carlisle PA has been sitting under a hose. She is in the dining hall and no one can head to their dorm it is raining so hard.
