Pendleton, OR – Temperatures across Eastern Oregon are climbing fast, with Pendleton expected to hit 90°F by Wednesday afternoon and 93°F by Saturday. The dry, sunny streak continues, raising concerns for dehydration, wildland fire risks, and road heat stress, especially along I-84.
According to the National Weather Service at Pendleton, calm winds will shift from the north Wednesday around 6 mph, under completely sunny skies. Thursday and Friday will bring highs of 84°F and 85°F respectively, with little overnight cooling—lows remain in the upper 40s to mid-50s. By Saturday, intense sun will push the thermometer to a summerlike 93°F.
Locals and travelers along Interstate 84 should take heat precautions, especially during midday hours. Wear light-colored clothing, avoid prolonged outdoor work, and check vehicles for overheating. With no rain in sight, dry grass and brush in Umatilla and surrounding counties remain vulnerable to ignition.
Although Sunday brings a slight chance of showers, the pattern stays mostly dry and warm. Sunday highs will still reach the upper 80s, with Monday holding steady in the upper 70s under mostly sunny skies. No major weather systems are expected through early next week.
Stay alert for possible weather updates if wind patterns shift or humidity drops further. The National Weather Service may issue additional advisories if fire danger increases or thunderstorms emerge heading into the first week of June.
