| Area Forecast Discussion National Weather Service Seattle WA 849pm PST Fri Jan 16 2026 Synopsis A strong high pressure system will remain in place over the Northwest through the weekend and into next week. The ridge will begin to flatten somewhat by the middle of next week, with a chance for precipitation returning late next week. Short Term - Tonight Through Sunday Night East winds are continuing in the Cascades and the gaps this afternoon, and skies have cleared across western Washington. Northerly winds persist through Puget Sound with some obs getting between 20-25 mph. This wind profile will continue into Saturday, although at slightly slower speeds. With the drying effects of easterly winds, the minimum relative humidities have been lowered, particularly in the southern Washington Cascades. The ridge will position itself more overhead over the weekend, for continued clear skies with afternoon highs around 50 and lows in the 30s. Long Term - Monday Through Friday Dry weather holds on as the ridge remains in place through the first half of the week. By midweek, the ridge is forecast to flatten, opening the door a touch for weak systems to brush the region. Quantitative Precipitation Forecast returns to the forecast, although light at this time, on Thursday into the later half of the week. 21 Marine High pressure will remain offshore through the weekend into next week, with a thermal trough along the shore. Few gusty spots will see winds decrease this afternoon in the coastal waters (with the last remaining small craft advisories expiring this afternoon for gusty east winds). There are no wind concerns through the next seven days, with the next weather system potentially arriving late next week. Seas will remain at 4-6 ft through the forecast period. HPR Hydrology No river flooding is expected in the next 7 days. NOAA Seattle WA Office: Watches - Warnings - Advisories WA...None. PZ...None. |
