Clear skies and low 90s at Sky Harbor this morning are just the warmup act. Phoenix is headed for a muggy, very hot afternoon, with meteorologists calling for a high near 107°F and apparent temperatures pushing into the low 110s. By late day, showers and thunderstorms could bubble up and drag sudden gusty winds and brief heavy downpours across parts of the Valley.
Afternoon Storms And Gusty Outflows
Storms are expected to fire over the higher terrain first, then try to roll into the Valley late this afternoon, with the best window roughly between 4 p.m. and 6 p.m. Any cell that survives the trip downhill can kick out strong outflow winds and quick bursts of heavy rain, with gusts of 30–35 mph possible near the stronger storms. The National Weather Service is flagging the risk of blowing dust and sudden visibility drops in parts of southern Maricopa and Pinal counties, so drivers are urged to give those storms plenty of room on the roads (NWS Phoenix).
Thursday Into Friday
A disturbance sliding in Thursday into Friday is expected to juice up shower and thunderstorm coverage, upping the odds for locally heavy rainfall and pockets of flash flooding across eastern and central Arizona. Some storms could deliver intense rain rates of 2–3 inches per hour where cells repeatedly track over the same spots, although forecasters say the exact bullseye is still uncertain (NWS Phoenix). For background on how this week’s heat primed the atmosphere for this pattern, check out our earlier coverage (Valley Broils at 108).
Heat And Safety
Even with higher storm chances, the heat is still the main headline. Highs near 107°F and sticky overnight lows in the upper 80s mean almost no break after sunset, with heat index values near 110–111°F. If you do not have reliable cooling, the City of Phoenix operates Heat Relief sites, pools and hydration resources. Call 2-1-1 or see the city’s heat-response page for locations and hours (City of Phoenix Heat Response). Standard summer rules apply: avoid strenuous outdoor activity during peak heat, drink water often, and check on neighbors, pets and anyone working outside.
Evening Commute And Travel
For the evening drive, keep one eye on live radar and build in extra travel time. Sudden downpours and outflow gusts can slick up roads and knock down visibility fast. Slow your speed, leave more room between cars, and be ready for brief detours or delays where storms or dust make conditions too tough to see through.
We will post updates if watches or warnings are issued and as conditions change. Before heading out this evening, check local forecasts along with official National Weather Service and City of Phoenix resources so you know what you are driving into.
