A rain shower Sunday night dropped the first measurable moisture since July 23 at Sea-Tac Airport. That ended the dry stretch at 48 days, the second-longest on record.
The record is 51 days set in the summer of 1951 at Sea-Tac.
"This is like losing a high-scoring basketball or football game by only 1 point....really frustrating! There is a significant chance this will be the only rain Sea-Tac gets out of the frontal passage," KPLU weather expert Cliff Mass wrote in his blog.
The National Weather Service says the showers won't last long. Warm dry weather is forecast for Western Washington for the rest of the week.
The front that brought rain to the west side of the Cascades is moving through Eastern Washington without much moisture, but gusty winds will fan wildfires. A red flag warning for wildfire danger covers much of the Inland Northwest until 11 p.m. Monday. Forecasters say winds should decrease Tuesday and dry weather continues the rest of the week.
