 resources. This is the heat bears down this 4th of July holiday. Triple digits forecast for much of the south and plain states. It'll feel about 110 degrees in Dallas and in Arkansas the heat index closer to 116. This is Americans plan to celebrate their independence with fireworks. This man owns a firework stand in Texas. Honestly I don't think the heat bothers everybody wants their fireworks when it comes to firework time nothing will stop people from coming.
