Heat Wave

We have a terrific heat wave going on right now. Our air conditioner is running full-time and having trouble keeping up. It is set on 78 and is keeping it at 80 now. They say the temperature outside is 90 with a heat index of 104. We are retired and able to stay inside but I sure feel sorry for those who have to work outside in this weather. We are supposed to have a cold wave go through tonight. I use the term "cold" loosely because it will only drop the nighttime temps down to maybe 60 which is still warm. We will probably have a storm but they talk about it going NE of us. I hope so.
