Olympia Regional Airport,
National Weather Service official reporting station closest to Yelm
While summers in Puget Sound are usually dry, this summer is a record-breaker in some official weather reporting stations here.
– Olympia Regional Airport
While Olympia Regional Airport’s National Weather Service station recorded near the August average of .05 inches of rain with .04 inches, which occurred on August 26, there have been only traces of precipitation since the last measurable rainfall on July 20. No rain is expected for the first ten days of September, as well, with temperatures well into the 80s returning mid-week.
– Sea-Tac Int’l Airport
Seattle is a different story according to the Associated Press on King-5-TV News:
“The gauge at Sea-Tac Airport has gone to the end of August without a drop rain.
If it stays that way through Friday [Aug. 31] as expected, it’ll break the record of 0.01 inches of precipitation, making it the driest August on record.
The record of 0.1 inches was set in 1974.
The current dry spell could also challenge the 51-day record set in 1951. The last rain at the airport was .04 inches on July 22. That’s 40 days and counting.”
