Marine Weather and Tide Forecast for Hoodsport, WA

SHORT TERM /TODAY THROUGH SUNDAY/
Strong north flow on the backside of a trough that passed through the region in the past 48 hours will continue to remain in place today. A ridge will build Saturday over the east Pacific Ocean, moving ashore during the day, and into Sunday. A small trough within this ridge is expected to dissipate per the ensembles.

Radar remains relatively quiet this morning. A couple showers along the coast and in the Cascades remain present, but these are light in nature and are not expected to produce any impacts. Skies early morning are a mix of mostly clear/mostly cloudy, with the clearest spots in the south interior. This cloud layer is expected to remain aloft this morning for all but the mountains. A frost advisory continues for the south interior through 9 am, as temperatures have already dipped into the 30s, and remain on track to dip into the mid 30s with the clearer skies. Areas that have cloud coverage this morning will see morning lows dip to around 40/upper 30s. Once the sun comes up, majority of the clouds will burn off, with highs reaching the mid/upper 50s to low 60s today. Saturday will be a near copycat to Friday, with morning clouds being a bit more widespread, and warmer overnight temperatures. The frost impacts are expected to be minimal at this time, but a couple south interior places may see lows dip into the mid 30s Saturday morning. Highs Saturday will climb into the mid and upper 60s, with some doubt if the cloud coverage will hold more into the day and hinder the temperatures.
Winds during this period will remain generally light at 5-10 mph between the south and north.

Sunday will bring the next chance (40-50%) of showers to the coast as a large upper low digs southward over the Pacific Ocean. The remainder of the coverage area will stay dry Sunday with more clouds. Highs on Sunday will peak during the next 7 days, with highs potentially reaching the upper 60s to low 70s. This will linger into the early work week. Again, some doubt remains with the cloud coverage, but the building ridge and high pressure will warm up the region quite a bit. Average for this time of year is around 60 degrees.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/
As the weekend comes to an end, ensemble guidance remains in good agreement that the upper low to the southwest will make its way inland. For Monday, we'll continue to see Minor HeatRisk across the region with daytime highs around 70 degrees. This brings some potential for increased moisture to wrap around the upper low and bring precipitation chances to the region Tuesday and Wednesday. This will also usher a return to temperatures closer to normal values across the region. While there's a bit more spread in the ensemble guidance later in the week, a return to drier conditions is favored for midweek and beyond.

AVIATION
Strong north flow aloft will continue in wake of a trough the passed through the region past 48 hours. The north flow will weaken into Saturday as the next ridge axis moves ashore. Conditions for a majorly of terminals will remain dry (couple of showers will move along the coast this morning and the Cascades). MVFR ceilings have developed across the Puget Sound terminal. Ensembles favor most sites seeing a low-end VFR cloud deck by sunrise this morning (lower ceilings are likely towards the Cascades). Additionally, a couple terminals in the south interior remain clear, but the likelihood of lower visibilities remain very low. Skies will clear through the day with VFR conditions prevailing into early overnight Saturday. Mid and high level clouds are favored to build, keeping probabilities for lower ceilings/visibilities very low in the forecast. Light/variable south winds this morning around 4-8 kt will shift to the north late this morning/afternoon.

KSEA...Mix of MVFR and VFR at times through 15-18Z, then VFR for the remainder of the day (slight chance of MVFR Saturday morning, although these may be hindered by mid level cloud development).
Winds southwest 4-8 kt will shift to the north at or just after 18Z.

MARINE
High pressure remains over the waters today, weakening into Saturday as the next low pressure system slides southward from the Gulf of Alaska. This low will remain offshore beyond the coastal waters this weekend into the start of next week, but an associated front will cross the waters on Saturday. This will bring a return of southerly winds over the waters, but this front won't be particularly strong with only a 30-40% chance of small craft gusts over the outer coastal waters (lower elsewhere). Expect seas to build to 6-7 ft over the coastal waters, largest beyond about 30 NM from shore where winds will be strongest. As a result, expect choppy conditions in these short period waves. A series of very strong ebb currents on the Grays Harbor bar can be expected during the early morning hours for the next several days.

Elsewhere and otherwise, not much in the way of impactful marine conditions expected through the early portion of next week.
Another disturbance may bring stronger northwest winds to the coastal waters as well as seas approaching 10 ft closer to the middle of next week.
