Slight welcome drizzle overnight in parts of western WA and a marginal improvement in fine particle pollution levels along the coast. Not much, but we'll take what we get. Air is still Unhealthy or worse in most of the state.
All the smoke models that ran overnight overdid the amount of clearing this weather system brought. According to them there should have been areas of Green and Yellow on the map by this morning. How we wish they were right! Therefore we're we're going for a persistence forecast. That is, expect the status quo to continue. Not pinning too much hopes on the weather system and slight rain expected tonight either. Substantial clearing is will have to wait until the Friday- Saturday timeframe. Here's the forecast for tomorrow. Nothing we havent already seen.
Later today we will provide some data analysis comparing this smoke season to past years. If our readers would like to see informative data products, please let us know and we will try, within reason, to prepare the most relevant plots/ tables. A friend of mine wanted me to issue a hyper-local, personalized forecast showing how his house will have clean air while everyone else had to endure hazardous conditions. I said no. Same goes for data products.
