Re: Severe Weather - Week of May 22 Sunday thru Thursday
I have two friends in OK. One is in Meeker (east of OKC) and the other about 2 hours north (I think).
They are both very, very frightened.

Re: Severe Weather - Week of May 22 Sunday thru Thursday
The storm moving through Chickasha and Blanchard is huge. I'll try and report from OKC if anything major develops in the metro area.
