Forecast models are suggesting that 500 millibar heights could reach 6,000 meters this weekend and that 850 millibar temperatures will rise into 99 degrees. What does that mean? It means that it’s going to be oppressively hot in Arizona and that records are likely to fall. The model forecast “would be at historic levels,” said the Weather Service, “rivaling the June 1990 heat wave.”

It was during that heat wave that Phoenix recorded its highest temperature to date — 122 degrees on June 26, 1990. In fact, Phoenix has hit 120 degrees only three times before.
