FIRST ALERT: Extreme heat grips Desert Southwest as temperatures push near record levels
YUMA, Ariz. (KYMA, KECY) -Â Saturday is a Weather Authority First Alert Day due to the hottest stretch of weather so far this year.
An Extreme Heat Warning is now in effect through Monday evening for most of the Desert Southwest, including southeast California and southern and central Arizona.
Daytime highs across the lower deserts are expected to soar between 110 and 114 degrees, putting the region under Major HeatRisk conditions especially on Sunday, when temperatures will come within a few degrees of daily records.
Saturday's forecast calls for highs around 110 degrees across the lower desert zones, climbing 3 to 4 degrees higher on Sunday, which is expected to be the peak of the heat. Overnight lows will offer little relief, with limited cooling and humidity staying in the single digits during the day.
A weak weather disturbance is forecast to pass north of the region late Monday into Tuesday, bringing a slight dip in temperatures and an increase in afternoon breezes. However, the change will be minor. By Thursday, the ridge is expected to build back in potentially bringing another round of high temperatures close to the 110-degree mark, and flirting once again with major heat risk thresholds.
Looking further ahead, some long-range models suggest the possibility of moisture creeping in from the southeast a possible sign of early monsoon influence but for now, the pattern remains too dry to support any meaningful rain chances.
Fire weather concerns also remain elevated. Dry conditions, gusty afternoon winds, and extremely low humidity will combine to create favorable conditions for wildfire spread, especially Monday as the weak disturbance moves through. Winds could gust over 20 mph in localized areas.
Residents are urged to stay cool, stay hydrated, and avoid strenuous outdoor activity during peak heat hours. Heat-sensitive individuals and pets should take extra precautions.
