The Smoke Outlook For The Adjacent Week
Air lineament today is far ameliorate over the portion today that end week, exactly some fume is acquaint in addition to volition remain present.
Here is the latest surface particulate map from the wonderful Washington State fume website : http://wasmoke.blogspot.com/. Most of the sites are dark-green (good air quality)....but at that spot are work spots. Because of the Maple Fire on the Olympic Peninsula in addition to persistent wildfires on northern Vancouver Island, some fume is getting into western Washington. That is why a few primal Puget Sound sites are reporting moderate levels (but on the depression marking of moderate). And the persistent fires on the northeast slopes of the Cascades are producing moderate to unhealthy values there.
This designing is going to remain inward house for the side past times side week, based on on the latest model runs. Forecasts are for the maintenance of a ridge of high pressure level offshore in addition to mostly northwesterly flow--no oestrus wave--but the Vancouver Island fume tin waft into western Washington. To illustrate, hither is the forecast map for upper marking (500 hPa) stream at five PM Saturday. No oestrus wave. Generally onshore flow.
The entrance of clouds into our portion has revealed a work alongside the NOAA/NWS HRRR fume model I convey shown inward previous blogs. It bases its burn place on satellite information (like VIRS) in addition to when clouds occur, the fires are non good defined. The Canadian fume model seems to produce better.
I suspect that nosotros convey seen the worst of the fume for this flavour hither inward western Washington, in addition to therefore it is useful to sentiment a draw of air lineament at Seattle to larn some perspective (see below for June 28th through today). Particulate levels (PM2.5) were relatively depression through around August tenth (although at that spot was a pocket-size spike on July 4th). We had 2 weeks of smoke, alongside some peaking into the real unhealthy hit (above roughly 120). Now nosotros convey settled downward into low-moderate marking (roughly 15-20)-- some smoke, exactly far downward from the previous peaks.
Finally, for those living inward Seattle, a novel fume measuring site has been position on transcend of my edifice at the UW, thank you lot to the USA Forest Service (and peculiarly thank you lot to Susan O'Neil of the FS that supervised its installation). This link volition larn you lot at that spot (see graph at 8 AM Midweek below)

It is interesting to compare this against recent years. For 2017, at that spot was a 2 calendar week catamenia inward early on August, that was bad, exactly non quite every bit bad every bit this year.
And 2015, a much warmer twelvemonth that this one-- a summertime similar to what nosotros facial expression during the 2070s, had far less fume that this year.
Clearly, at that spot are subtleties to the connection betwixt fume in addition to weather, something I volition explore inward a hereafter blog.
