Thanks to Bill Bacon for the post-sunset view of the Olympics and the Sound on yet another warm late-summer night (with smoke from the “Big Hump” fire, now up to 800 acres). Get ready for an even-warmer weekend, according to most forecasts (you’ll see a couple options on our experimental WSB Weather page). Today and tomorrow might approach 90, according to the National Weather Service, which says that might make for a record-setting week, before things cool down several days from now:

The warmest week on record in September in Seattle (including the Federal Building records, which go back to 1891) in terms of high temperatures is the 7-day stretch from September 18th through the 24th, 1974, when the average high temperature was 84.0 degrees (78…80…88…88…84…81…89). There is a chance this could be surpassed with the two warm days coming up over the weekend.

Still lots of outdoor options – before we get to today’s official preview, two that come to mind are the final weekend at Colman Pool (swimming resumes today at noon), and the all-weekend Holy Family Community Street Fair (9 am-6 pm today, 9-4 tomorrow).
