Key Insights

  • The National Weather Service has extended a cold weather advisory for western Washington.
  • Overnight temperatures are expected to fall into the low to mid 20s, with some areas potentially reaching the upper teens.
  • The advisory is in effect from midnight Saturday to 9 a.m. Sunday and includes a broader stretch of Puget Sound, from Everett and Marysville south through Seattle, the Eastside, Olympia, and the lowlands of Pierce, southern King, Lewis and southern Thurston counties, as well as eastern Kitsap County.
  • Forecasters warn of potential frostbite or hypothermia with prolonged exposure, especially away from the water.
  • High pressure offshore will keep western Washington dry through the weekend and likely into much of next week, but it will also allow temperatures to drop sharply overnight.
  • Winds are expected to relax Saturday night, which could allow patchy freezing fog to develop in fog-prone areas, particularly in the southwest interior, with the best chance early Sunday morning.
  • Snohomish County warming centers are open. To find information and the nearest center, visit https://snohomish-county-public-safety-hub-snoco-gis.hub.arcgis.com/pages/cold-weather-shelters?ref=yanuki.com.
  • The region’s mountain snowpack is falling behind, with some areas reporting less than 50% of normal precipitation for this point in the season. This is a concern as winter is typically when the Northwest builds its snowpack, which helps support water supply later in the year.
  • As of Friday, Sea-Tac Airport marked its 11th straight day without measurable rain, defined as at least 0.01 inches. The January record for days without measurable rain is 15 days, and western Washington could tie or break that mark next week if the dry pattern holds. This streak is the ninth time the Seattle area has had a 10-day or more dry streak in January since records started at Seattle-Tacoma airport in 1945.

In-Depth Analysis

The cold weather advisory highlights the potential dangers of prolonged exposure to low temperatures, particularly for vulnerable populations. The dry streak, while providing sunny skies, is also impacting the region’s snowpack, which is crucial for water supply later in the year. The combination of cold temperatures and lack of precipitation presents challenges for both individuals and the environment. Checking local news and weather updates regularly is recommended to stay informed about changing conditions and potential impacts.
