A broad swath of Southern Arizona will remain under warm, breezy conditions through Monday as a storm system tracking across the Great Basin keeps winds elevated across the region. Forecasters say this pattern will hold temperatures near seasonal averages, producing mild starts to the day for many communities and afternoon readings that push into the 80s and low 90s in spots such as Tucson. The gustier conditions are expected to linger into Monday before easing later in the week while the sky remains occasionally brushed by high clouds.

Overnight temperatures will vary by location across the region, with many places waking to relatively mild conditions. Tucson is forecast to drop to about 61 degrees Sunday morning, and much of Pima County will see lows in the 50s and 60s. West of the Tucson basin, communities such as Ajo and Organ Pipe are also expected to see overnight readings near 61 degrees, while cooler desert outposts like Sasabe could fall to around 52 degrees before the sun rises.

The eastern portion of the region will follow a similar pattern. Across Cochise County, overnight lows are forecast to be comfortably cool but not cold, with Sierra Vista dropping to roughly 56 degrees and other communities in the county generally starting the day in the 50s. Those morning readings set the stage for afternoons that warm into the 80s for much of Cochise County and surrounding valleys.
Daytime highs will be pleasant to warm across much of Southern Arizona. Tucson is expected to climb to about 92 degrees Sunday afternoon, making it one of the warmer spots in the local forecast. Many other communities — including Ajo, Sasabe and Vail — are projected to reach the 80s, while Sierra Vista in Cochise County is forecast to top out near 81 degrees. The combination of mild mornings and warm afternoons reflects a region-wide pattern driven by the mid-level storm influence and a continued influx of relatively dry air aloft.
Winds are forecast to remain a notable part of the weather story through Monday. The storm system to the north is maintaining breezy to windy conditions across the area, and while models suggest winds should gradually abate during the second half of the week, residents should expect gusty periods for the next couple of days. High clouds associated with the same pattern are expected to move across the region intermittently, limiting overnight radiational cooling at times and contributing to the mild overnight lows in many locations.
Local weather resources remain available for residents who want more detailed timing and hourly conditions. Hourly forecasts and seven-day outlooks provide finer-scale timing for temperature changes, and radar products can show any transient cloud bands moving overhead. Weather alerts and current conditions, including station-based temperature and dew point readings, are also maintained for those monitoring day-to-day shifts in the pattern.
A series of fact and data products accompany the daily forecast, offering snapshots of current temperatures, today’s highs and lows, dew point values, and precipitation summaries for Tucson and the state. Additional datasets track recent rainfall deficits and the longer-term drought picture across Arizona. These tools are intended to help residents and interests track short-term fluctuations as well as broader trends through the coming days.
The near-term forecast therefore calls for a continuation of warmer, breezy conditions through Monday with a trend toward lighter winds later in the week and periodic high clouds moving overhead. Overnight lows will generally be mild, commonly in the 50s and 60s across the region, while daytime highs will warm into the 80s for many communities and reach the low 90s around Tucson on Sunday.
