Mostly cloudy and roughly 82°F at Sky Harbor midday Monday, July 13, Phoenix is staring down another hot, sticky afternoon. Forecasters expect a high near 106°F with heat index readings around 110°F, followed by a slight chance of late-day showers and thunderstorms as mountain storms try to push into the Valley. Overnight lows only dip into the mid 80s, so the muggy air will hang around after dark.
Afternoon Storms And Gusts
Typical monsoon behavior is on tap, with isolated to scattered storms developing late this afternoon into the evening, especially after 5 p.m. Any thunderstorm could bring brief heavy rain and sudden gusty winds. Outflow winds near stronger cells may be powerful enough to kick up dust and knock down visibility, so treat storms as localized and fast moving rather than all-day soakers. These timing and impact details come from forecasts and discussions from the local office of the National Weather Service, which is tracking late-day thunderstorm chances for the lower deserts.

Heat Peaks Midweek Then Trends Cooler
Temperatures are forecast to climb into the upper 100s into Tuesday, July 14 and hold near 108°F on Wednesday, July 15, with heat index values in the low 110s. That adds up to a period of widespread Moderate Heat Risk with pockets of Major Heat Risk in some neighborhoods. By Thursday an easterly disturbance may broaden storm coverage and push highs down into the 90s to low 100s by the end of the week, with the best chances for more widespread showers and locally heavier rain later in the week.
Where To Cool Off
If you do not have reliable air conditioning, the city and regional Heat Relief Network operate cooling centers, hydration stations and respite sites across the Valley. You can call 2-1-1 or use the regional map to track down the closest location. The City of Phoenix keeps an up-to-date heat safety and relief guide that includes tips, the Heat Relief Network link and contact details for local services. City of Phoenix
Quick Safety Tips
Shift strenuous work and exercise to early morning or evening hours, drink water regularly, check on neighbors and pets, and never leave children or animals in parked cars, even for a short stop. If you run into heavy outflow winds, fast-falling visibility from blowing dust, or rapid flooding from a downpour, slow down while driving and move to higher ground. Call 9-1-1 for life-threatening emergencies.
