Arizona's extreme heat continues with rising storm chances
Extreme heat continues in Arizona alongside rising humidity and incoming severe storm potential.
PHOENIX - Extreme heat continues for the next couple of days, coupled with increasing humidity and storm chances.
What to Expect Today:
An extreme heat warning continues over much of the state, including most of Southern, Central, and Western Arizona. The warning will expire Monday evening in southern Arizona, Tuesday evening in Central and Southwestern Arizona, and Wednesday evening in Northwestern Arizona. The heat advisory over Northeastern Arizona will expire Monday evening.
While the heat lingers, the moisture levels over Arizona will increase gradually between Monday and Wednesday. With higher humidity, it will feel more uncomfortable outside each day. Plus, this will increase the potential for storms.
Monday afternoon and into the night, thunderstorms are expected to pass over southeastern Arizona, with some being strong to severe. These storms will pack strong to damaging winds and may kick up blowing dust. As a result, the National Weather Service has issued blowing dust advisories for portions of Pinal County, Pima County, as well as Graham, Greenlee, Santa Cruz, and Cochise counties through the evening. In Phoenix, gusty winds and blowing dust are possible between 7 p.m. and 11 p.m. A few scattered showers and storms will also be possible in Phoenix by Monday evening.
The Rest of the Week:
Over the next several days, the humidity levels will rise across the state and storm chances will increase, too. The best chance for storms remains over Southern and Eastern Arizona on Tuesday. By Wednesday and Thursday, more widespread storm chances are forecast. Again, any storms have the potential to pack strong winds, blowing dust, and heavy downpours as well as frequent lightning.
Temperatures will slip below 110 degrees in Phoenix by Wednesday, but just barely. The forecast high sits between 107 and 110 degrees from Wednesday through Friday. Storm chances will also sit between 10% and 30% each day of the week, with Wednesday looking the most promising in Phoenix for rain.
The weekend will remain near 110 degrees and additional storm chances are in the forecast.

The American Red Cross' tips for preparing for a severe thunderstorm:
- Put together an emergency kit.

- Create a household disaster plan and practice it.
- Purchase a battery-powered or hand-crank radio
- Discuss thunderstorm safety with members of your household. Be aware that a thunderstorm could produce flooding.

Be prepared and stay safe during the monsoon
"Most Valley residents know how quickly and furiously storms can move in and out, bringing strong winds, dust, rain, and flash flooding. These storms can cause interruptions in services, such as water, power, and gas," stated Captain Ashley Losch of the Glendale Fire Department.
GFD reminds residents of ways they can be prepared and stay safe:
- Have flashlights with extra batteries on hand.
- Have food that can be prepared without the need for cooking or refrigeration.
- Have at least one gallon of clean water for each person in the household.
- Have backup power for anyone requiring power for a medical device.
- Have backup power for cell phones that do not require charging.
- Have a first aid kit ready and accessible.
- Never drive into areas with flowing water; it takes less than 10 inches to wash a car away.
- Avoid flooded areas, such as washes.
- If waters are rising, seek higher ground.
- Do not approach downed power lines, the ground can be energized for up to 200 feet.
- Keep pets indoors during storms.
