The WHNT News 19 meteorologists strongly recommend you get a NOAA weather radio. It costs about $30 and will alert you during a severe weather situation, if programmed correctly.
Please get a NOAA weather radio with Specific Area Message Encoding, or S.A.M.E.
One such model is the Midland WR-100.
Midland's web site lists it as $49.95, but you can get it for about $30 at Batteries Plus,Wal-Mart and Kroger stores, as well as other retailers. Batteries Plus will program the radio for you when you buy it.
You can also watch the video clip above this story, as WHNT News 19 Meteorologist Brandon Chambers demonstrates how to program the Midland WR 100 model.
