The weather patterns across the state of Washington in the Pacific Northwest region are incredibly diverse. The driest 5-yr period on record was 1926–1930 with an annual average of 34.6 inches while the wettest was 1995–1999 with 51.0 inches. Les premiers habitants desEtats-Unis sont arrivés d'Asie il y a environ 30 000 ans lors de la dernière glaciation. The driest multi-year periods were the late 1920s, early 1940s, and late 1980s while the wettest periods were the 1950s, early 1980s, and late 1990s (Figure 2c). Ce prénom vient du germanique et remonte au Moyen Age. Current weather in Washington, with temperatures in 29 cities, including high and low temperatures for the country. Temperatures in Washington (orange line) have risen around 1.5°F since the beginning of the 20th century. As sea level has risen along the Washington coastline, the number of tidal flood days has also increased, with the greatest number occurring in 2010–2011 (Figure 6). Select a Washington city/area for current conditions and seven day weather forecast. This will increase the proportion of precipitation falling as rain instead of snow, leading to less snow accumulation during the winter. What’s New. Select sites by number or name. Whitely Binder, M. Krosby, and I. Tohver, 2013: Climate Change Impacts and Adaptation in Washington State: Technical Summaries for Decision Makers. Higher spring temperatures will also result in earlier melting of the snowpack, with average snowpack projected to decline by up to 70% by the end of the 21st century. The year of 2015 was the hottest on record with a statewide average temperature of 50.0°F, 3.9°F above the long-term average. The number of very hot days (days with maximum temperature above 95°F) has been quite variable, with numbers well above average occurring in the first decade of the 21st century, but below average numbers occurring over 2010–2014 (Figure 2b). Lewis, T.K.

Sea level rise has caused an increase in tidal floods associated with nuisance-level impacts. Since the beginning of the 20th century, temperatures have risen approximately 1.5°F and temperatures over the past three decades have been warmer than any other historical period (Figure 1). Updated Washington State weather maps. [, NOAA, cited 2016: Climate of Washington, National Oceanic and Atmospheric Administration. Narrative   Temperature increases will affect basins with significant snowmelt contributions to streamflow. Learn all about the climate of Washington State. Projected rising temperatures will raise the elevation of the snow line in the mountains. Washington’s location in the heart of the middle latitudes exposes it to frequent storm systems associated with the mid-latitude jet stream. In this way by coming of July it gains perfect state for different types of outdoor activities. Easterling, K.E. Nuisance floods are events in which water levels exceed the local threshold (set by NOAA’s National Weather Service) for minor impacts. These events can damage infrastructure, cause road closures, and overwhelm storm drains.
