Arizona weather forecast: Storms expected soon

Evening weather forecast - 10/7/25

Rain chances increase later this week, as Hurricane Priscilla brings moisture to the Valley. FOX 10's Erica Horvatin has the latest.

The focus of our forecast will shift from warming temperatures to rainy conditions over the next few days.

Today:

Temperatures hit 99 in Phoenix Tuesday afternoon, and low temperatures will only fall to around 71 degrees by Wednesday morning. The night will be clear and dry across Arizona.

Tomorrow:

Wednesday will start mostly sunny, and temperatures will climb into the upper 90s again. Clouds will increase during the evening and overnight.

Meanwhile, showers and thunderstorms will be possible around the White Mountains and east-central Arizona on Wednesday afternoon and evening. Some showers will be possible in far southern Arizona as well. The Valley and most of the state will stay dry, and humidity will stay low.

From Wednesday overnight into Thursday morning, chances of rain start to increase through the state. In Phoenix, chances of rain will increase to 30% on Thursday and Friday, too.

Later This Week:

Big changes arrive by Thursday morning, as humidity spikes, and widespread, scattered rain will move northward into the Valley.

The rain will continue north into the high country during the afternoon and evening. Isolated showers will remain possible in the Valley during the afternoon and evening.

Temperatures will stay cool, in the low 90s and 80s to end the week.

This Weekend:

This begins a five day stretch of soggy weather across the state, as remnants of Hurricane Pricilla move into the southwest. The heaviest, most widespread rain will continue on Friday, Saturday and Sunday. Flash flooding will be a higher risk on Friday and Saturday for most of Arizona, including the Valley.

At times, heavy pockets of rain will be possible, but the best chance for more widespread steady to heavier rain will be on Saturday. More rain, especially southeastward, will continue to move through on Sunday.

Hurricane Priscilla:

All these showers are due to a favorable pattern driving tropical moisture from Hurricane Priscilla up into Arizona.

The early showers (Wed-Thu-Fri) are due to moisture building ahead of Priscilla's center. Rain chances increase into the weekend as the center of the remnant moisture from Priscilla moves into the state.

An additional tropical system, which may become named, could potentially follow the path created by Priscilla and drive additional moisture into the state early next week Monday-Tuesday.

This long-duration rain potential brings the possibility of flash flooding. For now, it's too early to pinpoint where the heaviest rain will fall with the highest totals, but some areas of over 2" will be possible.

The exact track of Priscilla as well as the intensity (it could potentially remain a depression as it approaches Southern Arizona) will determine who sees the largest amounts of rain.

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 the 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.
