8 a.m. Tuesday: 120 degrees expected, with high pollution advisory 

Notice some extra haziness on your way to work? Pollution, and not your extreme-heat aversion, is the likely culprit.

More hot weather is expected today, with temperatures expected to climb to a high of 120 degrees in the Phoenix area, with 92 degrees as a low, according to the National Weather Service.

Maricopa County is still under a high pollution advisory issued by the Arizona Department of Environmental Quality. The agency advises limits on outdoor activity, particularly for children and the elderly, who are more vulnerable. 

The high concentration of pollution particles, or ozone, may have contributed to extra haziness this morning.  

9:25 p.m. Monday: 109 degrees, more flights canceled

Hot weather lingered over the Phoenix area long after sundown Monday, with the temperature still at 109 degrees in downtown Phoenix.

Earlier in the day, American Airlines announced it was canceling more than 40 additional flights it operates on its American Eagle commuter jet routes. The affected flights are scheduled to arrive or depart between 3 and 6 p.m. Tuesday, when the forecast calls for highs approaching 120 degrees.

Separately, the Maricopa County Sheriff’s Office reminded residents that it is a crime to neglect pets during the heat and that charges can be brought if someone leaves an animal in the heat or without water for an extended period. Officials also reminded people that if they see an animal in distress, they can do what they need to to assist the animal and likely avoid legal repercussions.

5:25 p.m. Monday: 117 degrees, flights canceled

Hot weather forced the cancellation of seven regional flights at Phoenix Sky Harbor International Airport Monday afternoon, according to a statement released by American Airlines. The flights, all between Phoenix and Tucson, were American Eagle flights that use Bombardier CRJ regional aircraft. Those planes have a maximum operating temperature of 118 degrees, which was the high for the day.

The airline has so far canceled more than 40 regional flights scheduled for between 3 and 6 p.m. Tuesday. The forecast for Tuesday includes a high of 120 degrees.

Customers affected by the regional jet flights should contact American Airlines for rebooking options or to request a refund.

4:15 p.m. Monday: 118-degree high ties record


Arizona has seen it all: record snow and rain, floods and drought, and the searing heat of summer.

The drop to 115 degrees was just false hope for a little relief as the temperature climbed to record territory a few minutes later. As of 4:15 p.m., the temperature at Sky Harbor Airport reached 118 degrees, which ties the record for June 16 set last year. 

That means June 19, 2017, also ties for the fifth-hottest day on record in Phoenix. In the more than 44,500 days since records have been kept, only four have been hotter.

4 p.m. Monday: Down to 115 degrees

The temperature at Sky Harbor had dipped to 115 degrees according to the hourly report from the National Weather Service. If the downward trend continues, we might not see a record today.

However, Tucson at least tied its June 19 record with a high of 115, so far. That temperature is the third highest ever recorded at Tucson International Airport. The all-time high for Tucson is 117 degrees on June 26, 1990. That’s the same day Phoenix saw its all-time high of 122.

3:25 p.m Monday: 117 degrees and climbing

The temperature at Sky Harbor Airport reached 117 degrees shortly after 3 p.m., Monday. That ties for the 15th hottest day on record in Phoenix, according to a Tweet from Paul Iñiguez, a meteorologist with the National Weather Service in Phoenix.

3 p.m. Monday: 116 degrees, out of the frying pan . . .

The temperature is still climbing, reaching 116 degrees just before 3 p.m.

While the heat can be miserable, some folks out there have been having a little fun with today’s weather.

Beth Cato put that old adage, “hot enough to fry an egg,” to the test with an experiment out in Buckeye.

Cato put an egg in a skillet and tweeted the results over the course of 2.5 hours. The skillet got to about 150 degrees and the egg did cook, eventually.

Check out the experiment at #CatoEgg.

2:30 p.m. Monday: 115 degrees, approaching record territory

The temperature at Sky Harbor Airport has reached 115 degrees, according to the National Weather Service. The record for this date is 118 degrees, set last year.

If we reach 118 today, that would tie the record for the fifth highest temperature recorded here since records were first kept. The city has seen 118 degrees several times.

2 p.m. Monday: 112 degrees and a high pollution advisory

Sky Harbor Airport reached 112 degrees by 2 p.m., Monday. That’s just six degrees short of the record for June 20.

Meanwhile, the Arizona Department of Environmental Quality has extended Monday’s Ozone High Pollution Advisory through Tuesday. With the weather forecast calls for more hot weather and calm winds, that advisory could continue for a few days.

Active children and adults and people with respiratory disease such as asthma should limit prolonged exertion outdoors during periods of high ozone levels. Given the extreme temperatures and the resulting excessive heat warning, everyone should limit time outdoors if possible.

1:30 p.m. Monday: Sky Harbor flights canceled

American Airlines has canceled some flights in and out of Phoenix on Tuesday afternoon because of extreme heat.

The cancellations are for operations by smaller regional jets that have lower maximum operating temperatures than full-size airliners. Those jets can’t operate when it’s 118 degrees or above.

American warned passengers over the weekend that it may have to ground flights during a heat wave that could send the temperature soaring to near 120 degrees. The airline is letting Phoenix passengers flying during the peak heat Monday through Wednesday to change flights without a fee. The forecast calls for a high of 119 Tuesday.

Extreme heat creates changes in air density that makes it harder for airplanes to take off.

1 p.m. Monday: 110 degrees. Getting closer to record

The temperature at Phoenix Sky Harbor International Airport was up to 110 degrees by 1 p.m., the third consecutive day it has climbed at least that high.

Considering forecasts have the city flirting with 120 degrees this week, 110 might not seem that significant, but that milestone has some meaning for those who pay attention to such things.

Saturday was the first 110-degree day of the year. That date, June 17, was seven days later than average.

Our current string of 110-degree days is expected to last through at least the end of the week. The record for consecutive 110-degree days is 18, set in June 1974.

Tucson reached the 110-degree milestone for the first time this year today.

Noon Monday: 108 degrees

Halfway through the day and we’re already well past normal.

By noon the temperature at Sky Harbor Airport has already climbed to 108 degrees. The normal high for the June 19 is 105.

We have a chance of setting a record high for the date if the temperature goes up another 10 degrees. The record of 118 was set last year.

The latest National Weather Service forecast calls for a high of 116.

The excessive heat warning issued last week by the National Weather Service has been extended. The warning is now set to expire at 9 p.m., Saturday.

Along with the heat comes the potential for burns, and not just the sunbathing variety.

Dr. Kevin Foster of the Arizona Burn Center said hot asphalt and concrete, playground equipment, vehicle interior surfaces and scalding water from outdoor hoses can lead to second- and third-degree burns when outdoor temperatures exceed 100 degrees.

“Young children are particularly vulnerable,” Foster said. “Not only is their skin more sensitive, but they haven’t learned how to remove themselves from the hot surface or object. Though they might be uncomfortable on the hot surface, they don’t understand why they are hurting or that they need to move.”

The same applies for pets: If the concrete is too hot to go barefoot, it’s too hot for them, too.
