Lisa it isn't much better here with every day pushing 95-100 and this has been going on for a couple of weeks. My lawn is completely dead except for the morning glory. Except for getting some pollinations done I stay inside all day. I wait for the sun to go down then go out for a walk and it is still hot but not burning. Apparently June had the highest average temperatures ever documented in this area. The forecast is more of the same on out.
I have already killed lots of plants when I miss a watering. Fortunately the lilies seem to tolerate it but they sure seem to blast through bloom a lot faster.
