Extreme heat! ABC15 weather action days until the weekend

PHOENIX – We are in for a long period of extreme heat that includes the Fourth of July weekend and the beginning of next week.

A Warning of excessive heat now applies to the Phoenix metropolitan area and most of southwest Arizona until at least next Tuesday.

Heat warnings are in effect for all of western Arizona, much of southern Arizona, and some of the lower elevations of northern Arizona through next Tuesday and Wednesday.

From now until Tuesday ABC15 Weather Action Days as a reminder to take steps to protect you and your family during this dangerous heat wave.

Spend as little time outdoors as possible in the afternoon, drink plenty of water and electrolyte drinks, and never leave children or pets unattended in the car.

Phoenix also set a new record on Friday, officially reaching 118 degrees, beating the previous record of 116 degrees set in 1983.

Highs in the valley will rise to 46 degrees this weekend and stay about that hot for most of next week.

High temperatures in Phoenix will continue to flirt with records on Saturday, Monday and Tuesday. The current record highs for Saturday are both 116 degrees, the record high for Monday is 115 degrees and the record high for Tuesday is 116 degrees.

The night temperatures also remain very warm, with temperatures throughout the valley only dropping to over 30 to under 35 degrees.

The warm mornings combined with the sweltering afternoons increase the risk of heat illness, so make sure you stay hydrated and limit your outdoor activities during the hottest hours of the day. Be careful of children and the elderly, as they are more susceptible to heat-related effects.

Monsoon moisture will be limited over the next few days, but some showers and thunderstorms may return to eastern and southeastern Arizona through Tuesday afternoon.

The biggest dangers in storms developing in Arizona are strong winds, dangerous lightning and small hail. There could also be downpours and flooding, especially along burn scars, so pay attention to the weather and never attempt to drive through flooded riverbeds or roads.

Air quality will also be a problem here in the valley during the holiday weekend.

ozone Warnings of high air pollution apply to the greater Phoenix area on Saturday and a ozone Warning of high environmental pollution on Tuesday. These warnings could be upgraded to advisories as we get closer.

If you have a respiratory condition such as asthma, bronchitis or COPD, you should limit your time outdoors as you may experience chest pain, cough, sore throat, stuffy nose or difficulty breathing.

Everyone should try to carpool, use public transportation, or work from home when air quality alerts are issued.
