PHOENIX — We're in the midst of an unrelenting heat wave with no end in sight.
High pressure overhead is bringing dangerously hot and dry conditions our way through at least the end of the week.
The heat won't let up this weekend either, and we could see even hotter conditions by the start of next week.
Daily highs in Phoenix will reach 113 to 118 degrees each afternoon through early next week.
Daily highs will end up within a couple of degrees of the record each day through the weekend, but we could set a new record by Monday. The forecast currently calls for a high of 115 degrees on Monday. Monday's record sits at 115 degrees set back in 1958. Wednesday's high could be record-setting, too. The current record sits at 116 degrees set back in 2020. We're forecasting a high of 118 on Wednesday.
Overnight lows will only cool into the 80s each morning through the weekend, and they could be even warmer early next week.
Excessive Heat Warnings for the entire Phoenix Metro Area and for areas in south-central Arizona have been extended again through next Thursday as the risk for heat-related illnesses stays high.
An Excessive Heat Warning is also in effect for the lower elevations of the Grand Canyon through the weekend.
We remain in ABC15 Weather Action Mode while these heat alerts remain in effect as an extra reminder that you need to take action to keep yourself and your family safe.
Heat is the number one weather-related killer. So, limit your time outside during the hottest part of the day and stay hydrated. Keep an eye on kids and the elderly as they can be the most affected by this heat. Bring your pets indoors, too.
The risk of wildfires is also going up as conditions stay very dry and winds increase this week. A Fire Weather Warning is in effect for most of northern Arizona on Friday. Outdoor burning is highly discouraged as fires can start and spread out of control very easily under these conditions.
Air quality continues to cause issues for people with respiratory conditions, too. Ozone High Pollution Watches is in effect for the Phoenix area for Sunday and Monday. Ozone pollution could make breathing difficult for kids, older adults, and anybody with respiratory conditions the next few days so you may want to limit your time outdoors.
While we're nearly a month into the monsoon, there are still no signs of rain for the Valley. However, we could start to see storm chances go up in southeast Arizona and the high country early next week. Stay tuned for updates as we get closer.
