Synopsis
Upper level high pressure strengthens through the end of the week with the air mass warming steadily each of the next several days. The warmest temperatures so far this season are expected late in the week as the ridge expands overhead. A weak disturbance arrives early next week to bring a return of rain chances and cooler temperatures.

Short Term - Tonight Through Saturday
High pressure and offshore flow continues across western WA today leading to warm and dry conditions. Temperatures were mostly in the 60s across the region this afternoon under clear and sunny skies. We'll see one more cool night tonight with a few spots dipping back into the 30s (like Hood Canal and SW Interior). Temperatures will nudge upwards a few degrees each day then peak over the weekend. By Saturday, most spots in the interior will see 70s with a few low 80s possible - a good 20-25 degrees warmer than average. The coast will be cooler and in the 60s (although still above average) due to NW flow. 33

Long Term - Sunday Through Wednesday
The ridge will start to weaken/flatten over the Pac NW on Sunday but we should still see one warm and dry day (similar to Saturday). The flow will then flip back to onshore on Monday while a weak frontal system moves inland. There's not much rain associated with this system. A stronger onshore push will likely bring more clouds and cooler conditions Monday night and Tuesday. Weak high pressure may rebuild over the region toward mid week for more dry and mild weather. 33

Marine
Northerly flow will continue for the majority of waters through Thursday with high pressure over the area. Small Craft Advisory winds for the central and southern coastal waters through this evening for increasing north winds. Winds will ease tonight through Thursday for light northerly winds. Offshore flow through the weekend with mainly light winds over the waters. Seas through the period will be below 10 feet.

Hydrology
River flooding not expected during the next 7 days.
