Marine Weather and Tide Forecast for Port Hadlock-Irondale, WA

SYNOPSIS
High pressure will build into the region through Thursday, bringing a return to drier and warmer weather. The next chance for showers will enter the region Friday, with unsettled conditions favored through the remainder of the weekend.

SHORT TERM /TONIGHT THROUGH FRIDAY/
Light post-frontal convergence zone showers and patchy fog will persist through the afternoon over King and Snohomish Counties before activity tapers off this evening with dry and cloudy conditions elsewhere. Highs today across western Washington are on track to peak in the 50s and low 60s.

A high pressure ridge will continue to amplify into the Pacific Northwest into Wednesday, with dry and mostly sunny conditions returning once the morning low stratus layer burns off.
Temperatures will peak in the upper 50s along the coast and in the 60s further inland.

High pressure will continue to build over western Washington on Thursday, with steadily increasing temperatures and clear skies.
Highs will peak in the upper 60s along the coast, with temperatures in the upper 70s across the interior. Some areas along the Cascade foothills and valleys may reach the low 80s. The lowlands will be warm enough for widespread Minor (Yellow)
HeatRisk.

The upper ridge axis will shift eastward on Friday as a trough approaches the coast. Southerly flow aloft will keep warm temperatures in place east of the Puget Sound, with Minor HeatRisk continued for these areas. A frontal system and associated band of rainfall will approach the Pacific Coast by mid-afternoon Friday, spreading inland late Friday into Saturday morning. Forecast models continue to trend this system slower, and it may arrive closer to Saturday morning.

LONG TERM /SATURDAY THROUGH TUESDAY/
The trough will split apart as it moves inland on Saturday, resulting in light rainfall amounts across western Washington. Split flow will develop over the region through the rest of the weekend, with lingering light shower activity possible. While operational models show a ridge developing overhead by the end of the weekend, ensembles maintain a chance of showers across the region into early next week.
