Info provided by NWS/NOAA:

Here are some definitions and guidelines to follow to help keep you and your family safe:

A Severe Thunderstorm Watch is issued when conditions are favorable for the development of severe thunderstorms, people located in and around the watch area should keep an eye to the sky and listen to their NOAA weather radio all hazards or tune to local broadcast media for further weather information. The watch is intended to give you time to prepare, time to review safety rules. 

A Severe Thunderstorm Warning is issued when a severe thunderstorm has been detected by national weather service doppler radar or a reliable report has been received. A warning is usually issued for portions of one or two counties, for an hour or less. If the warning includes your neighborhood or work place, you should take immediate action to protect your life and the lives of others. Severe thunderstorms can produce large hail and damaging winds. Tornadoes can and occasionally do accompany severe thunderstorms. Treat this warning the same as you would a tornado warning by taking the proper safety precautions. 

The best defense against thunderstorms is to stay inside a sturdy building or shelter that can protect you from deadly

lightning, large hail, damaging winds, flooding rain and tornadoes. Fortunately, thunderstorms typically do not last very

long and will most often pass by your location in less than one hour. Once in a shelter, stay away from windows and avoid electrical equipment and plumbing. Remember to bring pets inside. If there is time, secure loose objects outside as these objects often become dangerous flying debris in high winds.

Postpone outdoor activities until the storms have passed. If caught outside, take shelter in a sturdy enclosed building or hard top automobile immediately. Avoid open spaces, isolated objects, high ground and metallic objects. Get out of boats and away from bodies of water. Remember, if you can hear thunder, you are close enough to the storm to be struck by lightning.

If a tornado is spotted, act quickly and move to the lowest level basement of your shelter, putting as many walls between yourself and the outside as possible.

Review your safety plan now and be prepared when severe weather threatens your area!
