Hermiston hit 63 on Sunday, tying a record high temperature from 2011, according to the National Weather Service. The temperature also was 18 degrees above the city’s normal maximum.
Pendleton reached 60 on Sunday, no record but 15 degrees warmer than the normal maximum for the date.
The two towns also were almost 5 degrees warmer than usual for January, with the Round-Up City’s mean temperature at 39.9 and Hermiston’s at 39.6. Area highs remain in the 50s this week, with peaks in the lower 60s on Thursday.
The Weather Service also reported Pendleton and the surrounding areas have a possibility of rain, and the precipitation and warm weather means melting snow and ice will cause rivers and streams to rise through Monday. The Weather Service, however, has not issued flood warnings or advisories for Umatilla or Morrow counties.
This January also was far warmer than last year’s, when Pendleton’s mean was 22.5 and Hermiston’s 21.4.
