Arizona weather forecast: Excessive heat returning early next week

PHOENIX - Rain chances will drop heading into the weekend as temperatures begin to climb.

Sunday:

Sunday was a hotter day in the Valley, as temperatures climbed to 109 degrees. It has now been a full week of temperatures staying under 110 degrees, but that is about to change on Monday. 

The high country saw isolated light rain showers Sunday afternoon and most rain will end by around 8 p.m. A few showers could continue in south-east Arizona through later overnight. 

Extreme Heat Returns

Extreme heat warnings will start 10 a.m. on Monday across southern Arizona, and they will continue through Friday. This means that Phoenix city trails will be closed from 8 a.m. to 5 p.m. all week. Temperatures will climb into the low 110s each afternoon.

The Upcoming Week:

The weekend readings serve as a launching pad for significantly higher temperatures anticipated next week. 

Monday will be a mostly sunny day in the Valley. Showers and thunderstorms will be scattered in the high country during the afternoon and evening. The Valley could see blowing dust and gusty winds during the evening, and even a slight chance for a couple of showers or thunderstorms.

Rain chances will continue each day for the high country, but the Valley will stay drier this week, with the best chances for rain Thursday through Sunday.

This Past Weekend:

Saturday featured a mix of clouds and sunshine across Arizona during a relatively quiet day. The temperature reached a high of 107 degrees.

In Flagstaff, conditions remained pleasant with gray skies, a breeze out of the northeast, and a temperature of 72 degrees. The three-day forecast for Flagstaff shows very dry weather continuing. Temperatures there will climb back into the 80s on Monday and Tuesday with minimal humidity in the air, signaling an extended dry spell for the state heading into next week.

In the high country, overcast skies produced sporadic sprinkles along the Mogollon Plateau. Conditions are expected to continue quieting down during the overnight hours. Weather modeling indicates activity will subside around midnight moving into early Sunday morning, with only a slim chance for a sprinkle around noon.

An impressive shower moving across Interstate 8 near Gila Bend, though the storm lost intensity and dissipated. Farther to the east, earlier scattered rainfall also tapered off. Active weather was concentrated across parts of Mohave County, where heavy thunderstorms moved through on Friday night, particularly toward Lake Mead.

Big picture view:

Across Arizona, skies remain mostly fair, though a few showers appeared in the north alongside cloudy skies pushing into southern portions of the state. On the national radar, former Hurricane Lala continues to spin toward the Big Island of Hawaii. Although its eye is not exceptionally well-defined, and it is categorized as a minimal hurricane, the storm will push significant rainfall into Hawaii before the weekend concludes.

• 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.
