Phoenix Reaches 110 Degrees as Tucson Weather Turns Stormy

Phoenix hit 110 degrees on Saturday, marking its first 110-degree temperature of 2026 as tucson weather also tracked monsoonal moisture moving across Arizona. The reading came after a 106-degree high on Friday and arrived with clouds building across the Valley.

Ashley Loaeza reported Sunday evening that the first 110-degree reading was four degrees above normal, while the average first 110-degree day happens on June 11. Temperatures were expected to stay above average and keep nearing 110 degrees through next week.

Storms Across Arizona

Sunday showers and storms fired up across the high country and southern Arizona. More storms were possible to start the workweek, with a chance along northern and eastern Maricopa County as moisture moved in from the south.

Only light precipitation was observed in the Valley, and it was expected to remain dry on Saturday evening even as gusty winds and possible thunderstorms stayed in play for northern and eastern Maricopa County. That split left the Valley hot while nearby areas handled the more active weather.

Maricopa County Winds

Storms to the south could bring gusty winds, blowing dust, and dry lightning. Gusty winds in the Valley were expected by Tuesday night, and overnight lows were expected to be in the 80s as temperatures warmed through next week.

For people across Phoenix and surrounding areas, the practical takeaway is to watch for two separate conditions at once: extreme heat in the Valley and storm-driven hazards nearby. The heat stays elevated, while the storm chances focus on the high country, southern Arizona, and parts of Maricopa County.

June 11 Average

The calendar usually does not reach a 110-degree day until June 11, which puts Saturday’s reading ahead of the typical pace for the year. With temperatures expected to remain above average and gusty winds likely by Tuesday night, the stretch ahead keeps both heat and storm risks in view for the Valley.
