Change in Weather, Change in Plans

Well, the forecast for Saturday, the day of the wedding, is not looking good. Current predictions are for 50% chance of severe thunderstorms with large hail. Question--if it does rain/hail/lightning, will we be safe inside the tent? The lightning is a scary thing. It can strike up to 15 miles away from the storm. I've read of victims being struck while looking out the door of the garage. So, a tent with center metal spikes, probably would not be the safest place to be in the time of a storm.
