As the state's lead agency for water supplies, we pay close attention to multiple data sources and monitor them closely. The Office of the Washington State Climatologist serves as a credible and expert source of climate and weather information for the state. Their monthly newsletter reviews the previous month’s data and provides an outlook for the coming weeks.
Washington’s weather in May might best be described as “unsettled.” The year’s first heatwave kicked off the month, then there was a statewide thunder storm on May 30. Further snowpack losses in the East Cascades, leave Central Washington in abnormally dry to drought conditions, while other areas of the state received enough rain to make up for our dry April.
