Smoke Aloft
Published at 11:43 on 9 July 2021
Perhaps you have noticed it: the sky has a dingy aspect to it today, and sunlight is a little less intense and a little more yellowish than normal. The reason is smoke. There is wildfire smoke above us. It has not made it down to the surface due to the surface flow being onshore, so there have not been any real air quality concerns about it. (East of the Cascades, it is a different story; the smoke has made it down to the surface several times already there.)
This has happened once or twice before in the past week or two. Eventually, our luck will run out and the smoke will make it down to the surface. Although it is not known exactly when that will happen, it is early enough in the summer, with most of the dry season left to go, therefore it is almost certain to happen at some point. Hence my earlier warnings about preparing for smoke.
For this weekend, however, we should be safe. The smoke aloft is in fact modeled to depart by Sunday afternoon, so the sky should get clearer and bluer. Temperatures will be somewhat above long-term norms, but it will not be a heat wave by any measure. Highs should be in the mid-to-upper 70’s near the coast and into the low 80’s inland.
What we really need at this point is a summertime rain storm to reset the fire conditions, but nothing of the sort is modeled in the near future.
