PHOENIX — Our brief break from excessive heat is coming to an end as a strong ridge of high pressure builds back in over the desert southwest this week.
Monday expect partly cloudy skies with a high of 107 degrees and then we're back above 110 degrees starting Tuesday.
An Excessive Heat Watch is in effect Tuesday morning through Thursday night for Maricopa County, including the Phoenix metro, as well as other portions of south-central and northwest Arizona. This will likely get upgraded to a warning as we get closer.
This means Tuesday through Thursday will be Weather Action Days. Now is the the time to prepare yourself and your family for the dangerous heat. Stay hydrated, limit your time outdoors between 10 a.m. and 6 p.m. wear light colored clothing, use sunblock and watch for signs of heat related illnesses.
Air quality concerns also return early next week. An Ozone High Pollution Watch has been issued for Monday for the Phoenix metro, which could be upgraded to an advisory as we get closer.
Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body's ability to fight infection. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues.
Please help reduce ozone by driving as little as possible along with carpooling or using public transit. Also, re-fuel your vehicle in the evening and avoid waiting in long drive-thru lines.
The monsoon officially begins next weekend on June 15th.
The outlook this year has odds favoring another drier and hotter-than-normal season.
