North Texas is entering a heat advisory starting this evening and running for at least a week, with temperatures in the "triple digits." (Over 37^oC for those on the other side of the pond.)

On Friday I had my heat pump air conditioner repaired; it is 19 years old and the outdoors fan's sealed packed bearings were dried up (apparently it isn't something you can lubricate with a squirt o 3-in-1 oil). Good timing.
