This coming weekend, Seattle will experience the warmest weather so far this year, the U.S. National Weather Service reports. Temperatures will rise to 59–70°F (15–21°C), about 5–6 degrees above the seasonal average. Meteorologist Anna Lindeman notes that days will be mostly sunny, dry and nearly windless — ideal conditions for outdoor walks.
However, this warming is temporary. By next week temperatures will return to more typical values for this time of year, around 50–59°F (10–15°C). Lindeman emphasizes that while the long-term forecast points to a trend toward warmer weather, current levels are not record-breaking. A warm winter and a rainy March have already contributed to early blooming of plants in the region.
