Arizona is going to see colder temperatures later this week. Mark O’Malley, a meteorologist with the National Weather Service, said that means Valley highs in the mid 50s starting on Thursday and lasting through the weekend.
“We’re looking at a very large storm system, which will affect the state later this week,” O’Malley said. “Temperatures in Arizona will turn markedly cooler.”
O’Malley said highs in the northern parts of Arizona will only be in the mid 20s by Thursday. He said the storm system will also bring rain and some mountain snow on Wednesday and Thursday.
