The weather models today are even more out of phase than they were yesterday. There is just a slight chance of a high elevation, mainly dry, thunderstorm developing. Hopefully, things will be a bit more favorable for development tomorrow, we’ll see.
We have a mix of haze, high-altitude smoke, and clouds making the air quality look much worse than it actually is. The far northern portions of the forecast area are seeing more smoke than the southern portions are seeing.
I was asked to explain what the different numbers mean, here you go. This is from the EPA.
0-50: Air quality is considered satisfactory, and air pollution poses little or no risk.
51-100: Air quality is acceptable; however, if they are exposed for 24 hours there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution
101-150: Members of sensitive groups may experience health effects if they are exposed for 24 hours. The general public is not likely to be affected.
151-200: Everyone may begin to experience health effects if they are exposed for 24 hours; members of sensitive groups may experience more serious health effects.
201-300: Health alert: everyone may experience more serious health effects if they are exposed for 24 hours.
301-400: Health warnings of emergency conditions if they are exposed for 24 hours. The entire population is more likely to be affected.
To put this in perspective, during the 416 fire we had several days where our air quality index exceeded 500.
