NW TX and SW OK got plastered (again). Seeing multiple 10" reports on the eastern edge of the LUB CWA, around Guthrie and Dickens. Anxiously awaiting more LSRs from OUN, who haven't relayed any reports since early morning. I wouldn't be surprised to see somebody within 30 miles of LAW end up near a foot.

 

LUB totals:
