Those late afternoon thunderstorms usually are no big deal, unless they knock your power out. All that food in the refrigerator and freezer might spoil.
These tips from Baptist Health of Arkansas can make a bad situation better. First, keep the doors closed as much as possible to keep the cold air inside. If power is going to be out for several days, place a block of ice in the freezer, along with any foods you are trying to save. Dry ice works best in a stand-alone freezer.
When the power returns, check your food thoroughly. Throw out anything that's warm to the touch or has been contaminated by meat juices. Remember, it's better to be safe than sorry. When in doubt, throw it out.
