Forecast Discussion:
Calm weather conditions are expected through most of the week which will likely allow particulate levels be elevated during the morning hours. Afternoon heating should be enough to keep the atmosphere mixed well enough that we don't expect particulate levels to threaten the federal health standard. By Friday and Saturday, a low pressure system will begin to approach the west coast which should help improve ventilation and lower particulate levels. Overall, the dust risk is forecast to be Low through the forecast period.
