Synopsis
An upper ridge will keep the weather dry for most of the week ahead. A weak weather system will probably reach the area Saturday night or Sunday.

.SHORT TERM /TODAY THROUGH THURSDAY/...A dry weather pattern will persist for most of the week ahead. Expect afternoon temperatures warming to near normal after a chilly start to the morning the next few days. The cool spots will be the more wind-sheltered locations as offshore flow develops. The cross-Cascade gradient will increase through daybreak Wednesday, expect to see some breezy winds through the Cascade gaps. A weak front is expected to approach the coast late Wednesday into Thursday, but it will weaken and dissipate before it moves ashore.

Long Term - Friday Through Monday
Little change to the pattern into Friday with heigheights rebounding a bit for a continuation of the dry weather under high pressure with light offshore low-level flow. Temperatures likely hold near normal into the weekend. A slightly stronger front may then approach late in the weekend with ensembles suggesting slightly better chances for some light rain near the north coast. Dry weather likely continues into early next week otherwise, with a stronger front possibly reaching the area Monday or Tuesday. Cullen

Marine
Light flow this morning with offshore flow increasing this afternoon. Small Craft Advisory winds possible tonight for the western and central portions of the Strait of Juan de Fuca and the coastal waters with the offshore flow. Seas will gradually decrease through today as high pressure builds today.

Swells will begin to increase late tonight through Wednesday as model data shows a mixed swell developing through Wednesday. A secondary long period (greater than 20 seconds) westerly swell is expected to mix with the primary westerly swell at 14 seconds before becoming the dominant swell by Thursday morning. Swells will rise over 10 feet Wednesday night and remain above through early Friday. JD/Pullin

Hydrology
Dry conditions are expected through the weekend, with no river flooding is expected through the next 7 days.
