This is a , High speed Burst of Just how much rain and hail was coming down.
when that cloud passed by.
Also I have noted the fluxations in temps between 48 and 55 degrees.
about 5 minutes into this storm there was a flash. I didn't get it as I was making a sand which counted the count and at 3 and 4 there was thunder :) needless to say I left the kitchen area .
