Phoenix is heating up fast this Wednesday, July 22, with a sunny high near 103°F and only a slight chance of an overnight shower or storm before 5 AM. The National Weather Service has an Extreme Heat Warning in effect as readings climb toward near-record levels the rest of the week, so save the outdoor plans — Camelback Mountain hikes, South Mountain trails, or a Chase Field tailgate — for the coolest hours of the day.
Today’s Setup
Overnight lows held near 83°F with just an 11% chance of a passing shower or thunderstorm before 5 AM, mostly north and east of the valley. By daybreak, skies clear out and winds stay light at 0 to 5 mph out of the north northeast. Forecasters note a drying trend is taking hold as northwest flow and sinking air replace deeper monsoon moisture, so afternoon storm chances (just 6%) are isolated at best.
Best Window To Be Outside
Get outside before 8 or 9 AM if you want to walk, run, or hit the trails — after that, the desert sun takes over fast on the way to 103°F. Evenings offer some relief once the sun sets, though Wednesday night only cools to a low around 88°F before climbing back toward 90°F overnight, so even nighttime activities call for caution.
Extreme Heat Risk
This is the headline: the National Weather Service’s Extreme Heat Warning reflects a strong ridge of high pressure building in, with Thursday’s high forecast near 108°F and a heat index as high as 113°F. Forecasters expect this ridge to hold through Friday before any relief. Limit time outdoors during peak afternoon hours, drink water often, never leave kids or pets in a parked car, and check on elderly neighbors.
What To Wear Or Bring
Light, breathable clothing, a wide-brim hat, and sunscreen are musts today. Heading to tonight’s Diamondbacks game or a concert? A soft cooler backpack keeps drinks cold through a hot tailgate or a parking-lot wait.
Tonight’s Game And Live Music
The Arizona Diamondbacks host the Athletics tonight at Chase Field — first-pitch heat will be intense before things ease as the evening goes on. Grab an Arizona Diamondbacks jersey or Arizona Diamondbacks fitted cap for the game, and Find tickets on StubHub if you still need seats. Across town, Suki Waterhouse plays Arizona Financial Theatre tonight — Get tickets on SeatGeek before they’re gone.
Dinner Idea
With triple-digit heat outside, skip the grill tonight and let a programmable slow cooker do the work indoors — a pot of chili or beef stew is ready without heating up the kitchen. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Thursday brings the hottest air of the stretch at 108°F, and the ridge keeps things dry and sunny into Friday, with storm chances retreating into the higher terrain through the weekend, per the National Weather Service. Some relief and better monsoon storm coverage may return early next week. Looking further out, the Lindsey Stirling concert hits Arizona Financial Theatre on July 28 — a good one to plan for once the heat starts to ease.
If the heat has you stuck indoors, a 50-inch Pioneer 4K Roku TV deal is worth a look for catching the game from the AC.
