After a brief run of sweater weather, temperatures are heating back up in Phoenix, and a new set of potential records are up for grabs.
Monday through Thursday, temperatures will be inching close to 90 degrees in the lower deserts. If temperatures overperform, Phoenix could see the latest 90-degree day ever recorded.
The previous record was set on Nov. 15, 1999.
Austin Jamison, a meteorologist with the National Weather Service in Phoenix, said “overperform” is the key word as Monday, which is expected to reach 88 degrees, is the “week’s closest contender.”
“Right now, we are really only seeing a 25% chance of setting a new record Monday,” Jamison said. “It could wind up being a little warmer, but we think the most likely outcome will be hitting below the record.”
However, Tuesday is also expected to hit 88 degrees, meaning it would break the previous record of 87 degrees set in 2008.
“For Tuesday, there is a 50% chance of breaking that record and a 70% chance of at least tying,” Jamison said. “That’s pretty darn close.”
Temperatures will continue to gradually drop throughout the week with Wednesday at 88 degrees, Thursday at 86, Friday at 84 and Saturday dropping to 81 degrees.
With the high on Tuesday, Nov. 10, resting at 67 degrees, Jamison said the 21-degree increase over the course of a week is a “pretty big swing,” but fluctuating temperatures are not unusual for this time of year.
“This year, we’ve had unrelenting heat that we have gotten accustomed to having above-normal warmth,” he said. “We didn’t have the low pressure systems coming through in the summer. Now we do, and that’s what is behind these cool-offs and drastic changes.”
