Rain during Hot Weather

During hot weather, it is uncommon for there to be rain without lightning and thunder if the weather is hot. I find that the general rule of thumb is that if it is raining while it is 70 degrees or higher, it is usually accompanied with lightning and thunder but still sometimes can happen at colder temperatures too like during the spring. However is it possible for there to be 85 to 90 degrees F without any lightning and thunder?
