They want to make sure equipment, location of sensor equipment and other factors didn't artificially contribute to record heat or cold. From the NWS:

"The State Climate Extremes Committee has verified a new all-time Washington maximum temperature record of 120°F in Hanford, WA on June 29, 2021. This breaks the old record of 118°F set in Wahluke, WA on July 24, 1928, and in Ice Harbor Dam, WA on August 5, 1961."

And, Oregon got a mark too:

"The State Climate Extremes Committee has also verified a tied all-time Oregon maximum temperature record of 119°F at Pelton Dam, OR and Moody Farms Agrimet in OR on 29 June 2021. This ties the old record of 119°F at Prineville, OR on July 29, 1898, and Pendleton, OR on Aug 10, 1898."

According to the NWS, here's why the record temps occurred:

"1) A persistent ridge of high pressure
2) A widespread drought
3) Intense June solar radiation

This resulted in high temps well above 100, with lows in the 60s & 70s."
   The NWS says all in all, 128 all-time heat temp records were tied or broken across Washington state during the period of June 25-30, 2021. Whew!
