Pendleton, OR – Hot, dry air is barreling toward eastern Oregon this weekend, with a near 15-degree temperature surge expected by Monday. Pendleton residents should prepare now for intense heat, as Monday’s high could spike to 99°F, marking the hottest day of the summer so far.
According to the National Weather Service, Saturday (June 28) will be sunny and calm with highs near 84°F. Winds from the southwest at 5 to 9 mph will shift west in the afternoon. But by Sunday, the heat begins ramping up — highs will reach 92°F, and Monday’s scorching 99°F reading will challenge safety thresholds for outdoor workers and vulnerable groups. No rain is in the forecast through at least midweek.
Travelers along I-84 and U.S. Highway 395 should carry extra water and avoid car trouble by checking cooling systems before long drives. The dry air and clear skies will also increase fire danger across Umatilla County. Local officials have not yet issued red flag warnings, but residents are urged to avoid open flames and outdoor burning through early July.
Partly cloudy skies Monday night will offer little relief, with lows only dipping to 66°F. Tuesday stays mostly sunny and hot, reaching 96°F — the perfect storm for holiday dehydration if precautions aren’t taken ahead of July 4th.
