After a sweltering weekend, the Valley’s weather is set to go from one extreme to another and bring rain showers by Thursday.
The Valley experienced record high heat on Saturday, Sunday and Monday as temperatures reached 105 degrees in Phoenix and in east Mesa on Sunday, shattering a 63-year-old record. But a 30-degree drop in temperature is set to happen later this week, according to the National Weather Service.
A 70 percent chance of thunderstorms on Thursday is expected to cause the high temperature to be 80 degrees, said Keith Kincaid, meteorologist for the National Weather Service. The storm is riding into the Valley on a pretty strong low pressure system coming in from California, Kincaid said.
The rain showers are expected to come less than a week after Saturday’s temperatures reached a 102-degree high on Saturday, tying a 23-year-old record set in 1989, and the high of 105 on Sunday, breaking the previous record high of 99 degrees set in 1949, Kincaid said.
the high of 103 degrees on Monday also broke a 63-year-old record of 102, according to the National Weather Service.
The high temperature Tuesday was 96 degrees at 2:30 p.m., falling three degrees short of the record high set in 1987 and 1949, according to the National Weather Service.
The normal high temperature this time of year is 87 degrees, but a big dome of high pressure coming in from the Pacific Ocean parked itself over the Valley where it remained on Monday to heat things up, Kincaid said.
“We broke the record pretty good,” Kincaid said. “That’s only five degrees from 110.”
The dome of high pressure will move east beginning Tuesday.
A high of 102 was expected for Monday, then 97 on Tuesday and 94 on Wednesday, before rain moves in on Thursday.
“With a 70 percent chance of rain this far out, that means it’s a pretty good chance of getting rain,” Kincaid added. “It’s not unusual when we get storm systems coming in, but we were significantly above normal temperatures with those triple digits.”
People are reminded to drink a lot of water during the hotter temperatures, wear sunscreen and stay in the shade during the hottest part of the day. You also keep pets inside, or at least in the shade, and make sure they have plenty of water.
The rain on Thursday is expected to happen all day long, and temperatures on Friday are expected to climb back up to 84; high temperatures are expected to be 91 on Saturday and 93 on Sunday, Kincaid said.
