Pendleton, OR – Eastern Oregon residents face a colder turn in the weather this week, with frost expected around Pendleton early Tuesday and overnight temperatures potentially falling to 27 degrees by Friday night. The chilly conditions come ahead of NOAA's Oct. 26–Nov. 1 outlook, which favors below normal temperatures across much of Oregon as November begins.
According to NOAA's Climate Prediction Center, the eight to 14 day outlook issued Sunday, Oct. 18, favors below normal average temperatures across much of Oregon during Oct. 26–Nov. 1. Above normal precipitation is also favored, suggesting a cooler and potentially wetter pattern as the state moves into November.
Pendleton faces frost and temperatures in the 20s The National Weather Service forecast for Pendleton shows Monday reaching approximately 64 degrees under mostly cloudy skies.
Temperatures are expected to fall to around 35 degrees Monday night, with patchy frost developing after 2 a.m.
Areas of frost are also forecast before 8 a.m. Tuesday, followed by partly sunny skies and another afternoon high near 64 degrees.
Wednesday offers a brief warmup, with mostly sunny conditions and a high near 67 degrees.
However, the forecast becomes more unsettled Wednesday night, when a 20% chance of showers develops after 11 p.m.
Thursday brings a 50% chance of showers and a high near 63 degrees.
By Friday, daytime temperatures are forecast to fall to approximately 56 degrees, followed by a low near 27 degrees Friday night.
That would be the coldest overnight temperature shown in the supplied forecast and could bring freezing conditions to exposed vegetation and other temperature sensitive outdoor items.
Residents should distinguish the forecast frost from an official frost or freeze warning, which was not established in the supplied information.
Eastern Oregon faces a changing November pattern NOAA's extended temperature outlook places much of Oregon within an area favoring below normal temperatures.
That includes the Pendleton region of Umatilla County, although the strongest cooler than normal probability shading is concentrated farther west.
Across eastern Oregon, the outlook becomes less decisive toward the Idaho border, where the broader temperature pattern transitions toward warmer conditions farther inland.
The precipitation outlook favors above normal totals across much of Oregon, including the eastern part of the state.
That does not mean rain is expected every day or that a particular storm is forecast to arrive during Oct. 26–Nov. 1.
For Pendleton, the near term NWS forecast already includes additional shower chances Saturday and Sunday, with highs near 58 and 59 degrees.
Those daily forecasts cover a separate period from NOAA's extended outlook.
What residents should know before November Eastern Oregon's forecast differs from Portland's in one important respect: Pendleton is already facing specific frost and freezing temperature concerns.
While Portland's forecast shows daytime highs reaching the lower 70s early this week, Pendleton's overnight lows are forecast to fall into the 30s and eventually the upper 20s.
Residents with outdoor plants, exposed irrigation equipment or other temperature sensitive property may want to prepare for the colder nights.
Across the broader state, NOAA's outlook suggests cooler than normal temperatures could remain favored as November begins, accompanied by increased precipitation potential.
The maps do not establish snowfall amounts, snow levels or exact daily temperatures for the extended period.
Updated local forecasts will be needed to determine whether additional freezing nights develop during Oct. 26–Nov. 1.
