Marine Weather and Tide Forecast for Clallam Bay, WA

SHORT TERM /TODAY THROUGH THURSDAY/
A frontal system will move into B.C. today while a weak warm front clips western WA. This front will continue to spread clouds into the region with scattered showers mainly along the coast and near the Canadian border. With the increase in clouds, we're seeing warmer temperatures this morning with upper 30s and 40s expected. Expect highs in the 50s to lower 60s.

A cold front will weaken as it shifts S/SE into western WA on Wednesday. The coast, mountains and north part will see additional showers with the highest chances of seeing wetting rains on the North Coast.

High pressure will build over the region on Thursday for dry and warmer conditions. Expect highs in the lower 70s with 60s along the water. 33

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/
High pressure and offshore flow will bring one more dry and mild day on Friday. Temperatures in the interior will track a few degrees warmer with afternoon highs in the lower to mid 70s.
A trough will bring cooler and wetter conditions moving into Friday night and Saturday. A stronger and wetter Pacific system will reach the area Sunday/Sunday night and into Monday. This system has potential for stronger winds along the coast with wetting rains for the coast and mountains. Mountain areas over 5000 ft may see a few inches of snow too. 33

AVIATION
VFR ceilings in place across the area with a few scattered showers ahead of the next weather system. Moisture will increase this evening and into early Wednesday morning as the system bringing these clouds moves in from the northwest. Best chances for showers will be across the northern terminals such as CLM and BLI after around 06-12Z Wed. Expect ceilings lowering to MVFR across the north during this same window, with conditions spreading across the remainder of the area after 12z. Southerly winds increase a bit toward 10 kt after 06z tonight into early Wednesday.

KSEA...VFR ceilings continue into early afternoon under solid mid-level cloud deck. Light southerly winds become increasingly southwest and increase to around 7-9 kt this afternoon and evening.

MARINE
High pressure will shift inland and to the southeast as a low pressure system moves over Vancouver Island and slowly shifts to the south. Winds will likely remain below thresholds, but some slight enhancements in the wind just off the northwest Olympic Peninsula may allow for some gusts to reach 15-20 kt Tuesday and into early Wednesday. The frontal system weakens as it moves inland on Wednesday. High pressure will then build over coastal waters Wednesday night into the end of the week. With thermal troughing along the coast, this will allow for winds to turn offshore Wednesday night into Thursday. Some enhancement in the winds will be possible in the gaps in the terrain (West Strait of Juan de Fuca, Chehalis gap/Grays Harbor area). The thermal trough looks to move inland Friday, with onshore flow increasing Friday night into the weekend as a series of systems looks to approach and move across the coastal waters this weekend into early next week.

Seas will remain around 4 to 7 feet throughout much of the week before building to 8 to 12 this weekend and remaining elevated into early next week.
