Forecast Discussion: Updated Wednesday, October 16, 2019 High pressure is in control today and will only stick around through the first half of Thursday. This is the first favorable autumn setup for elevated PM10 levels around the County and so have several monitoring sites in the low to mid moderate range on the AQI scale today. Hidden Valley is making a run at exceeding the health standard for PM10 today as the five minute PM10 averages have spiked to concentrations at or above 1,500 ug/m3! Thursday will be another day where early morning light easterly winds will play a prominent role at Hidden Valley and so the daily average is forecast to approach the health standard, though is expected to remain just below due to breezy southwesterly winds Thursday afternoon. The breezy conditions are associated with a weak trough which will move through well to our north late Thursday/early Friday and help knock the temperatures back to more seasonal levels for this upcoming weekend. Ozone levels will remain in the good AQI category this week, though may flirt with low moderates today due to the aforementioned high pressure. Check back tomorrow for an updated air quality forecast. Forecaster: S. DiBiase
