PHOENIX — High pressure is building in and sending temperatures soaring!
Phoenix tied Tuesday's record of 108 degrees (set in 2002) and it's only getting hotter for the rest of the week.
An Excessive Heat Warning is in effect from 10 a.m. Wednesday morning through 8 p.m. Sunday evening.
That means, Wednesday through Sunday will be ABC15 Weather Action Days as a reminder to take action in these dangerously hot temperatures. Stay hydrated, limit time outside in the afternoon and never leave kids or pets in the car no matter how quick the errand.
Phoenix will likely hit 110 degrees or hotter starting Wednesday, which is unprecedented for this time of year.
The latest 110-degree day ever recorded in Phoenix was September 19, 2010. That record will be broken later this week.
Phoenix will also likely tie or break daily heat records Wednesday through early next week as temperatures top out between 108 and 112 degrees.
Since our nights are getting longer, we do not anticipate any 90-degree lows. Overnight temperatures will drop into the low to mid 80s across the Valley and those exceptionally warm lows for this time of year could set records this week, too.
Our drought has been worsening over the past few months with the hotter and drier monsoon we've experienced. There is less than a week left to get rain in the buckets before the monsoon season officially ends on September 30th and our rain chances are slim to none all across Arizona.
So far, Phoenix has only picked up 0.74 inches of rain this monsoon season. Our 30-year average (which is considered our normal amount of rain) is 2.43 inches. But, it's important to remember, that is a decrease from the previous 30-year average of 2.71 inches (from 1981-2010) as our Valley climate continues to get hotter and drier.
