Phoenix area will probably be under an extreme heat warning all week

The Phoenix area will probably remain under an extreme heat warning all week as temperatures remain dangerously high.

“Temperatures are really not going down anytime soon. In fact, they’re going to stay fairly stable over the next few days with highs around 110 in Phoenix and very, very warm overnight lows probably around 90 or even low 90s,” meteorologist Chris Kuhlman of the National Weather Service told KTAR News 92.3 FM on Monday morning.

The Valley has been under an extreme heat warning since Thursday morning. The warning was originally set to expire Monday night but has been extended at least until Wednesday night.

With even hotter temperatures in the forecast later in the week and into the weekend, the warning will most likely be extended again.

“I would say sometime today or tonight we will extend it even further, and it’s going to be even worse later this week and next weekend, where we’re looking at highs of 115 or so, maybe even as high as 118 in a few spots,” Kuhlman said.

The normal high temperature in Phoenix for this time of year is 106 degrees.

More records could fall during extreme heat warning

Phoenix set a daily heat record of 117 degrees last Friday. The low temperature that day was 97 degrees, matching the city’s all-time record for the hottest low.

More records could fall in the coming days, with the forecast calling for highs near the existing high marks of 116 degrees for Friday and Saturday and 114 degrees for Sunday.

Kuhlman said monsoon moisture and a high-pressure system are contributing to the persistent extreme heat.

The conditions could produce isolated monsoon storms this week, but any rainfall is expected to be in the higher elevations on the outskirts of the Valley.

“It’s really not going to make it into the lower deserts at all,” Kuhlman said. “With the high pressure overhead, it makes it very difficult for any storms to survive into the lower deserts. So, we’re not expecting anything in the Phoenix area except for maybe some gusty winds.”

How does the extreme heat impact metro Phoenix residents?

Extreme heat warnings trigger daytime closures of hiking trails at Camelback Mountain, Piestewa Peak and South Mountain in Phoenix.

Health experts urge precautions during times of extreme heat such as keeping hydrated, wearing light clothing and remaining indoors with air conditioning during the hottest times of the day.

The Maricopa County Heat Relief Network offers free, cool spaces and other resources to people who need relief from the heat from May to September.

Additionally, the Salvation Army opens 10 heat relief stations across the Valley during extreme heat warnings.
