Unseasonably Dry Conditions Across Washington State through Next Week

A ridge of high pressure in the eastern Pacific Ocean will keep storm systems away from Washington and will bring mostly dry weather state-wide for the next week. Stable conditions and light northerly flow will maintain generally quiet weather conditions with little chance for precipitation until late next week at the earliest. The most notable issues will be poor air quality and air stagnation concerns. While there will be subtle changes in the day to day weather, many areas will see abundant sunshine and significant day to night temperature fluctuations on those days. Nights will generally be quite cold, with highs warming well above freezing in most places during the day. Areas that see eventual night-time low cloud or fog development will have smaller diurnal temperature variability and warmer overnight temperatures. The mountains will be relatively mild and sunny for this time of year.
