Pendleton, Ore. – Summer heat is lingering across Eastern Oregon as residents brace for another stretch of sunny, dry days through Wednesday. With highs near 87 degrees expected on September 17, drivers and outdoor workers should prepare for above-normal temperatures, especially along Interstate 84 where heat can amplify pavement conditions.
According to the National Weather Service, Pendleton will stay clear and warm through midweek, with overnight lows holding in the upper 40s to low 50s. Light winds will shift throughout the day Wednesday, offering little relief from the sun. Officials urge travelers to carry water, check vehicle cooling systems, and avoid leaving children or pets unattended in parked cars.
The warm stretch is expected to persist through Friday, with temperatures climbing into the mid-80s before clouds gradually return this weekend. Saturday brings a mix of sun and clouds, followed by a slight dip in temperatures by Sunday night. Farmers and ranchers across Umatilla County should continue irrigation plans, as no measurable rainfall is expected through the next five days.
Residents planning outdoor events or work shifts should schedule early morning activities to avoid peak heat in the afternoons. Though the warmth brings ideal conditions for travel and recreation, safety precautions remain important during this unseasonably hot mid-September pattern.
Dry and sunny skies will dominate into next week, with only a modest cooling trend beginning Sunday. Additional updates are expected if temperatures climb further or fire danger increases.
