Phoenix Cranks Up The Broiler Again With 107-Degree Blast

As of Wednesday, June 10 at 5:35 a.m. MST, Sky Harbor was already waking up warm with clear skies and a temperature near 79°F. Phoenix is headed for another scorcher today, with a high near 107°F this afternoon and only modest overnight relief as lows hold in the mid to upper 70s across the metro. The air will stay on the dry side in the morning, so it may not feel swampy, but the heat will still be dangerous for anyone spending long stretches outside.

Afternoon Heat

Afternoons will surge into the mid to upper 100s, with most neighborhoods topping out around 105 to 107°F and some western desert spots flirting with 110°F by the weekend. Winds should stay mostly light, but they will turn westerly this afternoon and can gust into the teens, which can make outdoor work feel tougher than the thermometer alone suggests. If you have outdoor plans, aim for the early morning, seek shade when you can, and build in plenty of water breaks.

Late-Week Showers And Fire Risk

Moisture starts to creep back into the Valley late Thursday into Friday, bringing a slight, roughly 20 percent, chance of isolated morning showers or storms on Friday and again over the weekend. Most of that activity is expected to be high based with very little rainfall reaching the ground. According to the National Weather Service Phoenix, that setup boosts the risk of dry lightning and gusty outflow winds that can spark new wildfires even when rain is limited. Overnight lows will stay warm, generally in the upper 70s to low 80s, so both heat stress and fire concerns linger into early next week.

Heat Safety And Cooling Options

If you need a breather from the blast furnace, the Maricopa area Heat Relief Network lists cooling centers, respite sites, and hydration stations around the Valley. Check the interactive Heat Relief Network map for locations and hours, or call 2-1-1 for help finding a site or arranging transportation. Take precautions now: avoid heavy exertion during late afternoon peak heating, drink water often, check in on older neighbors and vulnerable friends, and never leave children or pets in parked cars, even for a short time.

Outlook

Expect a steady run of upper 100s in the afternoons and warm nights through early next week, with only isolated storm chances over the weekend. Keep an eye out for updates if any watches or warnings are issued for the Valley.
