Seattle has spent a full week with dense fog at times -- defined as 1/4 mile visibility or less -- courtesy of strong ridge of high pressure that created a monster inversion over much of the Puget Sound region.
The 7-day streak ties for the fifth longest all time (although well behind the "epic fog storm" of December 1985 when the city had 13 straight days with dense fog at some point.)
But what makes this stretch so memorable is not just dense fog for a few hours each morning, but for days on end with no relief in sight (or much else, for that matter.)
At one point during our week of fog, Seattle had a stretch of 80 consecutive hours Thursday through Sunday with fog at 1/2 mile visibility or less. The "break" in the fog lasted just 5 hours, and a new fog layer moved in Sunday evening.
That layer was even thicker, rattling off another 36+ hours of dense fog -- this time 1/4 mile or less of visibility.
But if you're tired of fog horns, missing hillsides, and not being able to tell what color the traffic light is more than a half-block away, we have some good news:
The rain is coming back.
I know for sun fans, that's like saying: "Hey, we're finally are going to fix that leaky faucet, but you won't have any hot water," but for those with respiratory issues and heating challenges, it'll be nice to clean the air and get rid of the burn bans. The fact that we might rediscover Kitsap County is an added bonus.
The rain will hold off until late Tuesday night or early Wednesday morning, but we should start getting some light breezes ahead of the rain to start mixing up the lower levels of the atmosphere and scour out the fog sometime Tuesday afternoon.
When that happens, not only will it clear up, but it will warm up fairly rapidly. The great secret for those who have been trapped in the 35 degree fog all these days is that it has been pretty warm outside the fog -- temperatures in the 50s have been common for days on the coast and up in the high hills. That warm air will mix in to where the foggy 30s of Tuesday morning and midday will become the cloudy 40s or low 50s Thursday evening -- and night!
More routine Seattle-esque rain will be around at times for the rest of the week and weekend. It'll finally mean goodbye to the fog.... and hello to Bainbridge Island.
