PHOENIX -- Temperatures are expected to soar Saturday in Arizona's desert region, approaching records.
The National Weather Service has issued an excessive heat warning for the southwest and south-central Arizona deserts that's set to expire early Sunday morning.
The forecast calls for a 112-degree day in Phoenix and 113 in Yuma, both 1-degree shy of record temperatures.
The 113 degrees at Sky Harbor International Airport on Friday tied a record set in 1992.
Meteorologist Hector Vasquez with the National Weather Service in Phoenix said temperatures usually are cooler around this time of year, aided by thunderstorm activity. But he said the state is on the drier side.
Overnight temperatures Saturday are expected to be warm as well, with lows between 84 degrees and 89 degrees in the desert region.
