Marine Weather and Tide Forecast for Ruston, WA

SHORT TERM /TODAY THROUGH SUNDAY/
Patchy, shallow, fog has formed once again this morning, especially in areas where the wind is calm. The fog will burn off later this morning. The previous discussion can be found below along with updates to the aviation and marine sections:

High pressure and offshore flow will lead to one more warm and dry day across western WA. East winds have peaked overnight with 40-50 MPH gusts in the Cascade ridges and 20-30 MPH in the gaps. Winds will continue to ease today. Temperatures will track warmer than average with afternoon highs in the lower to mid 70s. Expect 60s near the water.

Friday night/Saturday will be cooler and wetter as the ridge shifts east and a front and trough move in from the west. The bulk of the rain will fall tonight into Saturday morning and mainly affect the coast and mountains. Showers with a convergence zone are expected Saturday afternoon near the King/Snohomish line. A few sunbreaks are expected outside the convergence zone with afternoon highs in the 50s to lower 60s.

We're in between systems on Sunday for cool but dry weather.
Sunday morning lows will be in the 30s and 40s with temps near freezing around the south sound. Highs will be mostly in the 50s. 33

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
An upper level low will spin offshore on Monday, with showers mainly clipping the coast. This system will weaken as it shifts farther south on Tuesday, with light/dry offshore flow across western WA. A weak front dissipates as it reaches the region Wednesday night and Thursday for a chance of light rain. 33

AVIATION
A bank of shallow surface fog has arrived into the central Puget Sound area, impacting KSEA and at times, KBFI this morning. Areas of the southwest interior toward Olympia are also experiencing fog.
Have opted to extend the fog duration for these areas until 17Z.
Once the fog lifts, expect VFR cigs and visbys to return for the rest of the day. The next weak frontal system will arrive late tonight into Saturday for MVFR cigs. Light rain is expected through tomorrow morning, clearing up in the afternoon.

KSEA...Fog has become entrenched in the south end of the terminal as part of a shallow bank hugging Puget Sound. The fog is shallow, but has been visibility reducing in areas directly under it. Cigs are down to around 300 ft. This will linger until 17Z before beginning to scatter out. Once it does, expect VFR cigs throughout the rest of the afternoon and light southwesterly surface flow. Light rain has been introduced to the terminal toward the end of the TAF period as the next weak frontal system moves through the area.
