Pendleton, Ore. – Dangerous heat continues in Eastern Oregon as temperatures climb near 98 degrees Tuesday, keeping Pendleton and nearby cities under an Extreme Heat Warning until Wednesday evening. Haze and stagnant air will make conditions even tougher for drivers and outdoor workers through midweek.
According to the National Weather Service, Pendleton will stay hot and mostly sunny Tuesday with highs near 98°F before relief begins late Wednesday. A weak front will shift winds and bring a 30 percent chance of showers by Wednesday morning, with highs sliding back into the lower 90s.
Hazardous conditions remain possible on I-84 near Pendleton, especially during afternoon commutes when heat and haze combine to reduce visibility. Residents are urged to limit outdoor activity, drink plenty of water, and check on elderly neighbors. Pets should remain indoors during peak afternoon hours.
By Thursday, conditions ease with highs closer to 91°F, and Friday brings more comfortable mid-80s. That cooling trend holds into the weekend, giving Eastern Oregon a break from the heat just in time for Labor Day gatherings.
Travelers planning early holiday trips should expect dry weather from Friday through Sunday. No widespread rain is expected, but haze could linger in valleys before clearing out by Saturday.
Warnings remain in effect through Wednesday, with updates expected if thunderstorm chances increase midweek.
