National Weather Service Seattle WA
321pm PDT Sat May 8 2021
A weak weather system continues to make its way onshore. This will bring some very light rain showers to the Western Washington area but mostly it will be cloudy skies. As this weak system moves out of the area Sunday a ridge will build in behind it. Resulting in warmer and sunnier conditions.
Short Term - Tonight Through Tuesday
A weak weather system is making its way onshore this Saturday afternoon. Resulting in cloudy skies throughout Western Washington. This system is expected to bring some light rain to the area as it tracks inland. But it will not be much in terms of accumulation, just a few hundredths of an inch. Behind this system, there is the potential for a bit of a Puget Sound Convergence Zone to set up. Guidance is suggesting it will stay up around Everett as the Puget Sound region will be experiencing southerly flow. This could bring some additional rain showers, but even then it is not expected to be much. Things will begin to clear and dry out starting later Sunday as a ridge of high pressure builds into the area. The ridge is expected to be centered mostly offshore but will result in some warmer temperatures and dry conditions through much of the week.
Long Term - Wednesday Through Saturday
The start of the long term is expected to be the warmest day of the week. With highs in the 70s for much of the lowland areas. Dry weather will dominate through much of this period as well. A few weak disturbances could track through and result in some light showers, particularly in the northern portions of the forecast area. There has been some disagreement in the models as to how long this ridge will last. But based on the trends and guidance it is looking like the next wet system will arrive just in time for the weekend.
Varying degrees of onshore flow will continue into the first part of next week with high pressure over the coastal waters.
Small craft advisory level winds expected to start in the Strait during the day Sunday...during the afternoon for the central portion and late afternoon/early evening for the East Entrance. Coastal waters get close to criteria Sunday evening and Sunday night, but it is very borderline and as such will allow the decision to pull the trigger on these zones to be made by future shifts. Otherwise, wind speeds should remain below any headline thresholds at least into the start of next week. 18
The daily hydrology discussion has ended until the start of the next rainy season; it will only be updated as needed until then.
