PHOENIX - This weekend, stormy conditions will continue over the High Country with high heat across Central and Western Arizona.

Temperatures will remain above-average and over 110 degrees as high pressure builds. Not only will it be hot, but also humid.

Saturday:

Saturday was another hot day in the Valley with extreme heat finally ending as temperatures cool down with the arrival of widespread monsoon activity. It was a scorching start to the weekend with Phoenix hitting a high of 113 degrees. Overnight lows will be in the 80s.

Air quality as of Saturday afternoon has ranged from unhealthy for sensitive groups to moderate at times due to the dust and lack of rain and winds.

Phoenix heat wave nears record high before monsoon storms bring relief

Phoenix reached 113 degrees on Saturday as extreme heat peaks. Cooler temperatures and widespread monsoon rain are expected to arrive by Monday. FOX 10's Ashley Loaeza has more ahead of the cooler and active weather next week.

Sunday:

Sunday was another hot, humid day in the Valley. Temperatures climbed over 110 all weekend and reached 111 degrees Sunday afternoon. Showers and thunderstorms crossed Arizona’s high terrain throughout the afternoon and evening.

There is a chance for blowing dust, gusty winds and a slight chance for a few showers or thunderstorms in the Valley throughout the evening.

Highs reach 111 degrees with monsoon rain and dust risks

Phoenix recorded a high of 111 degrees on Sunday, as humidity increased, bringing chances for gusty winds, blowing dust, and evening thunderstorms. FOX 10's Erica Horvatin has more on when we can expect those storms to move in.

This Week:

Monday will be a dry and partly cloudy morning. The afternoon will be sunnier, and there will be a chance for scattered showers, thunderstorms and blowing dust Monday evening through the night.

Rain may continue into early Tuesday morning. The high country will see scattered showers and storms throughout the afternoon and evening. Temperatures will stay a few degrees cooler, with a high of 108 degrees in Phoenix.

Rain and Cooler Temps:

There will be daily storms in the mountains this week. The Valley will also see daily chances for rain, but it will be dependent on what happens each night. If we see a very active Monday night, Tuesday may be quieter in the Valley, before the chance of rain increases again on Wednesday.

Temperatures will keep cooling through midweek, as the high pressure dome shifts away from Arizona. The Valley could even see temperatures around the upper 90s and low 100s on Wednesday and Thursday.

As with most monsoon storms, there will be the potential for strong winds, lightning, and heavy rain. The chance for storms increased from 20% to 30% by Sunday in Phoenix.

Rain/flood safety tips

The American Red Cross' tips for heavy rain situations and flood safety:

Turn around don’t drown! If you must drive and you encounter a flooded roadway, turn around and go another way.
If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground.
Tune in to your local radio, NOAA radio, or news channels for the latest updates.
If your neighborhood is prone to flooding, be prepared to evacuate quickly.
Follow evacuation orders and do not attempt to return until officials say it is safe.
If power lines are down, do not step in puddles or standing water.
If power is out, use a flashlight. Do not use any open flame as alternate lighting.

Preparing for a severe thunderstorm

The American Red Cross' tips for preparing for a severe thunderstorm:

Put together an emergency kit.
Know your community’s evacuation plan.
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.
Pick a safe place in your home for household members to gather during a thunderstorm. This should be a place where there are no windows, skylights, or glass doors, which could be broken by strong winds or hail and cause damage or injury.

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.
