Arizona weather forecast: Highs in the low 90s expected this week

Plenty of changes expected over the next week!

Today:

Monday was a completely sunny and dry day across Arizona. Temperatures started climbing Monday, with highs reaching the low to mid-90s in the Valley.

Tonight will be clear, with lows in the upper 60s in the Valley. Meanwhile, temperatures will fall into the 30s, 40s and 50s in the high country.

Tomorrow:

Tuesday will be another gorgeous day, but it will be a bit warmer. Temperatures will climb into the upper 90s in Phoenix with sunny skies, and will be warmer than normal across Arizona. 

The forecast high jumps to 97 on Tuesday, and 99 Wednesday and Thursday, in Phoenix.

Later This Week:

We could hit the low 100s on Wednesday, as high pressure strengthens east of Arizona. Isolated showers will be possible in eastern Arizona Wednesday afternoon and evening.

The exact location of rain and the amounts of rain will be dependent on that track. The quantity of rain could also keep our temperatures much cooler than normal. 

Rain Chances:

The second half of the week will be a lot wetter. Starting Thursday, the chance for showers and storms begin to increase.

High pressure will sit to our Southeast. Low pressure and a trough will sit to our northwest. At the same time, Hurricane Priscilla will slowly track northward parallel to the Mexican west coast.

It will approach to the southwest as it weakens. Thanks to the pattern, a wind funnel will set up directly from the area of Priscilla toward Arizona. This will boost our moisture content and allow for storm chances to rebound around Arizona.

For now, it appears moisture will increase and, rain chances in turn, between Thursday and early next week. While each day will not be a washout all day, there will be the potential for periods of steadier rain around Arizona, including in the Valley.

At this point, the best chance for rounds of rain appears to be western and northern Arizona.

However, this is a very contingent forecast on the movement of Priscilla over the next 2–4 days. Either way, rain chances will increase and temperatures will moderate into the weekend.

Driving in extreme temperatures

The Arizona Department of Transportation’s tips for driving in extreme temperatures include: 

Have sun protection: In addition to an umbrella, take sunscreen and a wide-brimmed hat and wear loose-fitting, light-colored cotton clothing.

Fuel up: Keep your tank at three-quarters full. Running out of gas, especially in a remote location, is dangerous in extreme heat.

Hydrate: Take a cooler to keep extra drinking water cold, and consider adding several frozen bottles of water to use for cooling off or to thaw and drink if needed. Make sure everyone, including pets, stays hydrated.

Get help: If your vehicle breaks down in extreme heat, call for assistance right away to reduce wait time, and run the AC. If the AC isn’t working, roll down all windows.

Wait safely: If the temperature inside your vehicle becomes too hot, everyone, including pets, should exit carefully and seek out or create a shaded area as far away from the travel lanes as possible. Be careful walking on the road surface, which can be hot enough to burn skin. Keep your shoes on and try to keep your pets’ paws off the pavement. If you are stopped along the highway, raise the front hood and turn on hazard lights. Please keep in mind that parking in tall brush can start a fire. 

Check your vehicle: You can help avoid breakdowns and blowouts by making sure your vehicle is in good operating condition. Check your air conditioner and coolant levels, top off any vital engine fluids and make sure your battery is up to par. Check your tire pressure, as the combination of under inflated tires and hot pavement can lead to a blowout.
