I rely on my smart phone and the Weather Bug app. It sends alerts to you based on the phones location. No need to set up the weather radio with SAME codes.
On the other hand if I am in a location with poor or no cell phone service then I use my Oregon Scientific WR601 radio. I so seldom use it that I have to read the directions each time I want to set it up. It is a portable unit that you can carry with you if you want as long as you are staying in the same area that the SAME codes are set for.
For outdoor temperature, again I use my cell phone most of the time. I do have a rather cheap I/O digital thermometer.
You will find the Weather Bug app even has a lightning check on it that will tell you how far you are from lightning strikes.
