Phoenix extreme heat warning extended amid near-record high temperatures

The Phoenix-area extreme heat warning that started Sunday has been extended until Tuesday.

The warning originally was set to expire Monday night. Instead, it will remain active until 8 p.m. Tuesday.

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

The forecast calls for a near-record high of 109 degrees on Monday. The current record for May 11 of 110 degrees was set back in 1934.

It will be a tad cooler on Tuesday, with an expected high of 107 degrees, 2 degrees below the record for the date.

“It’s not quite as hot as what we would get during June and July, August, but it’s still quite hot,” Chris Kuhlman of the National Weather Service in Phoenix told KTAR News 92.3 FM on Monday morning.

Phoenix temperatures are expected to reach the lower 100s or upper 90s for the remainder of the week. The normal high for this time of year is 93 degrees. The Valley is looking at overnight lows in the 70s.
