Good Morning Mr. Rawles,
You probably already know about this, but there are several good quotes in this article about the massive scope of the damage from nothing more than a few lines of strong thunderstorms over two days rumbling through my neck of the woods.
Even central valleys in interior states can suffer damage similar to a large tropical cyclone, so folks shouldn’t get cocky and fail to prepare. As an aside, I finally purchased and just yesterday put into service my new NOAA alert radio (a Midland WR-300), programmed in the local SAME code(s), and got to hear that warning siren several times last night! Even though the storms were fairly severe, luckily for us the tornado activity stayed northwest of our location by about 30 miles. – Mike in S.E. Virginia
