This heat wave has proved itself to me in Pittsburgh. Officially hit 90 today, fifth day in a row. Was 94 yesterday, but the dew point was about 56, so, it wasn't too bad. We've been very lucky to have generally low dew points the entire time. A few spikes here and there, think it peaked around 68 one morning, usually falls to near 60 or lower later. Today, is the best chance of rain we've had in 8 days, and that's not even guaranteed.
Also, looks like next week the heat returns. Could we have a record hot July?
