Don't scare yourself out of going somewhere:
Get appropriate weather apps AND a weather radio. That weather radio will shriek at you until you get up and listen to it - very important when the storms come in at night.
Watch/listen to local weather forecasts. Use your apps/internet connections to check out the weather forecasts for where you're going that day.
Always know what county you're in and what adjacent counties are, so you'll know if/when you're in a watch/warning area.
Don't drive into a wall cloud. Wait it out.
Just be weather alert. In time, it will become second nature.
I grew up in Tornado Alley. It's not anywhere near as scary as some like to portray - as long as one pays attention.
