Marine Weather and Tide Forecast for Southworth, WA

SHORT TERM /TODAY THROUGH FRIDAY/
Satellite imagery shows stratus along the coast, over the Northwest Interior and down the Cascade foothills to about I-90.
Low level onshore flow bringing marine air into the interior with temperatures at 3 am/10z in the upper 40s to mid 50s.

Upper level ridge centered well offshore with northwesterly flow aloft over Western Washington the next couple of days. Low level onshore flow will weaken later today into tonight with northerly flow in the lower levels Thursday. Stratus over the area this morning will dissipate by 10 am/17z leaving sunny skies for the remainder of the day. Less stratus Thursday morning with the low level northerly flow. Highs today in the mid and upper 60s along the coast and upper 60s to mid 70s inland. A little warmer Thursday with highs near 70 coast and 70s to lower 80s inland.
Increasing northerly winds Thursday afternoon. Lows tonight in the upper 40s to mid 50s.

A little bit of troughiness developing offshore Thursday night into Friday switching the flow aloft to west southwesterly. This will send some high clouds our way but that is about it. Light flow continuing in the lower levels. Highs Friday near 70 along the coast and 70s to mid 80s inland.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/
Upper level ridge remaining offshore through the weekend with varying degrees of low level onshore flow ( increasing onshore flow Saturday weakening Sunday ). Offshore ridge building and moving closer to the area the first part of next week for a couple of warmer days. Highs Saturday in the mid to upper 60s coast and 70s inland, Sunday near 70 coast and 70s to mid 80s inland. A little warmer Monday and Tuesday with the coast in the lower to mid 70s and the warmer locations over the interior getting close to 90 degrees. No rain in sight the next 7 days.

With the continuation of the above normal temperatures Seattle looking at a possible top 10 and maybe a top 5 warmest June if the trends continue. The first half of the month was the 10th warmest in Seattle and above normal temperatures will continue for the next week at least. Felton

AVIATION
Currently VFR across all the terminals early this morning, with the exception of the coast. Latest satellite imagery shows marine stratus hugging the coastline and beginning to develop over portions of the interior. Latest guidance is still suggesting that the southern interior, Kitsap Peninsula, and coast have the highest chances of seeing MVFR cigs between 11z-20z, with latest probabilities between 30-65% (highest chances along the coast).
Other terminals have a very small chance of 10-20%. Otherwise, VFR expected for all terminals this afternoon. Light to calm winds for the interior terminals early this morning. W/NW winds will increase this afternoon to 5-10 kt. Breezy winds expected along the coast this afternoon, with gusts to 20 kt.

KSEA...VFR conditions through the TAF period. Light variable winds overnight will become W/NW in the afternoon and increase to 5-8 kt.
Winds shift NE after 04z-06z at 5-7 kt.

MARINE
Broad high pressure over the NE Pacific will keep weak high pressure over Washington's waters. High pressure over the waters will then begin to weaken late Thursday as a low pressure system slowly moves across British Columbia through Saturday. As the low pressure system pushes to the east, broad high pressure over the NE will begin to build east into area waters and will strengthen into early next week.

Elevated northwesterly winds and seas are expected across the coastal waters throughout the week. Guidance suggests a 70% chance or higher of 21 kt winds across the coastal waters, especially the outer coastal waters. Westerly pushes are expected through the Strait of Juan de Fuca this weekend. However, at this time winds look to remain below small craft thresholds, as the latest probabilities are around 20-35%.

FIRE WEATHER
The return of low level onshore flow has eased fire weather concerns for the next couple of days. Elevated fire weather concerns return Friday and the first part of next week with a few warmer and drier days. Minimum relative humidity values are forecast to drop to around 30 percent Friday and during the first part of next week. Breezy conditions in the afternoon and evening hours combined with the lower relative humidity values could be problematic especially with the fuels continuing to dry out in the next week. Felton
