 Arizona News Radio, I'm John Gilliland. The Phoenix area is flirting with 100 to 20 degree temperatures all this week. And if the mercury climbs that high, it would be only the fourth time in the city's history, says Matt Salerno, meteorologist with the National Weather Service in Phoenix. In 1990, we actually hit it twice. We hit 120 and then 122, which is our record high for Phoenix.
