Clean Air Returns, First Storm of the Season Likely Midweek

The air is clean!! Puyallup’s 8 PM air quality reading & forecast shows the best AQI in over a week! 


It is now safe for everyone to be outside! If you went outside today, the air felt clean! The AQI forecast shows clean air lasting for the foreseeable future! Hopefully this is the last time for awhile that you will see air quality in the blog.

This month has flown by. Fire weather/smoke was first mentioned in the blog on September 2nd. After over 2 weeks, the fire weather and smoke event is finally over! Now, our attention turns to our first autumn storm of the season!

Here is the UW model showing moisture in the atmosphere at 11 AM Wednesday.

Reds and blues indicate more moisture in the atmosphere. See the current of moisture aimed at us? That is the upcoming atmospheric river event.

It’s literally what it sounds like. A river of moisture (rain) will set up and aim right at the Pacific Northwest. In winter, we call this a Pineapple Express (as air comes from the area of Hawaii). 

Now what you probably want to know...how much rain will we get?

The consensus among the forecast models gives our area 1-4 inches of rain and winds gusting 30-40 mph between Wednesday (23rd) and Friday (26th). Forecasts aren’t certain on exact storm track, timing, and impacts.

I will have this information in future blog posts. For now, be prepared for a typical autumn storm that will give us plentiful rainfall and send us in to a likely stormier fall/winter.

Enjoy the clean air!!
