PM10 - 19 Good
As temperatures climb back into the mid 80F range, airmass remains very dry with dew points around 50F, clear skies, and very light winds, conditions are favorable for increased ozone production and accumulation. The one uncertainty is the lateness in the year and whether there are enough daylight hours before the onset of the nightly inversion (and subsequent scrubbing of ozone by the continued emissions of NOx at the surface). The forecast is for moderate air quality, but anyone that is particularly sensitive to ozone pollution should monitor air quality closely tomorrow (9/30/2026) as hourly ozone concentrations could creep into code orange territory even if the 8-hour average remains in code yellow.
