Since it’s quiet in here, thought you might like to see what my tree trunk looks like after my direct strike from June 29 with the tree removed yesterday. Pretty wild.

This is what it looked like about 5 minutes after the latest STW was issued, and about 2 minutes before the "really good" rain hit...

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.
