Seattle weather: Tuesday will be the warmest of the week
A Heat Advisory remains in effect for Western Washington through Wednesday night as temperatures climb into the 80s and 90s.
SEATTLE - A Heat Advisory will remain in effect through Wednesday as toasty summer temperatures continue across the Puget Sound area.
A few temperature records are within reach today, especially around Bellingham. Tonight will stay unusually warm, with many locations only cooling into the upper 50s and lower 60s.

Cooler air returns Wednesday
The weather pattern begins shifting Wednesday as the ridge moves east of the Cascades and onshore flow strengthens. In simple terms, cooler Pacific air will begin pushing back into Western Washington.
Temperatures will still be warm, but most communities will see highs about five degrees cooler than Tuesday. Inland areas should top out in the mid-70s to mid-80s, while coastal communities cool into the 60s. Increasing high clouds will bring in that filtered sunshine look.

Clouds increase Thursday
Thursday marks the beginning of a significant weather transition. Cloud cover will thicken throughout the day as the first organized weather system in a couple of weeks approaches the Pacific Northwest. While most inland locations should stay dry during daylight hours, rain could begin reaching parts of the coast during the late afternoon.
Temperatures will continue their downward trend, with highs settling into the 60s and lower 70s.
Rain returns Friday
The biggest weather story of the week arrives Friday. A cold front is expected to sweep across Western Washington during the day, bringing widespread rain and breezy conditions. The rain will transition to scattered showers behind the front, and the atmosphere may become unstable enough for an isolated thunderstorm or two Friday afternoon.
A Puget Sound Convergence Zone is also possible Friday afternoon and evening, potentially setting up across Snohomish County or perhaps even parts of northern King County. Localized heavier showers could occur where it develops.

Cooler this weekend
By Friday night and Saturday, an unusually cool upper-level low will settle over the region, keeping showers in the forecast and temperatures well below normal. Highs on Friday and Saturday are expected to remain in the upper 50s to mid-60s. Some locations could challenge record-cool daytime temperatures for late June.
Sunday and Monday look a bit better, with temperatures returning to the 60s. A few showers may still linger at times, but the steady rain should be over by then.
A dramatic cooldown will hit Western Washington on Thursday, with rain back on Friday. (FOX 13 Seattle)
