The second-driest start to May on record in the Seattle area will end in time for rain today, on Mother’s Day, the National Weather Service said.
Saturday was expected to be the final dry day in a stretch that began April 30, said meteorologist Dana Felton.
“We’ve got a system coming in,” he said Friday.
Eleven dry days at the beginning of May would be the second-longest period since 1946 when it didn’t rain until May 24.
Oddly, this dry spell follows the second-wettest April on record.
“We had a really fast transition, not only to really dry but to really warm,” Felton said.
The rain late Saturday was expected to drop the high temperatures in Western Washington back to the more-normal 60s.
The front will lower Eastern Washington’s 90s, but the high temperatures are expected to remain in the 80s east of the Cascades, even with some clouds.
“They could see showers and thunderstorms but not the steady rain like we get over here on the west side,” Felton said.
Many rivers in Eastern Washington and the Idaho Panhandle are running high because of melting snow in the mountains. Minor flooding is expected on the Okanogan, Kettle and Stehekin rivers.
