Cindi discussed the how and why to Thunderstorms. They have to have moisture, unstable air and lift which usually comes from cold/warm fronts.
Severe Thunderstorms can be as high as 60,000 feet high and have winds of 58 or more mph. They can also produce tornadoes.
Lightning occurs with all thunderstorms. You need to take cover inside a building so that you have a better chance of not getting hit. You count the seconds between the flash and the thunder and then divide by 5 to get how many miles the storm is away.
Heat lightning seen in the summer sky is really a storm too far way for you to hear the thunder.
Cindi said 88 percent of tornadoes are weak ones. They last 1 to 10 minutes. Strong tornadoes comprise 11 percent with winds of 110 to 205 mph and may last as long as 20 minutes or longer.
The violent tornadoes make up less than 1 percent and can exceed an hour in length and 205 mph winds.
She told us that hail can fall as fast as 100 mph.
Cindi also covered a lot of myths over tornadoes. If your interested in seeing what she covered you can go to this web site.

The weather service also has a myth page on storms as well.
She stressed the importance of having a weather radio. Her final words of advice were, "Your best defense is to stay informed."
