Forecast Discussion:

The stagnant ridge pattern in place today transitions towards low pressure troughing by Wednesday. Stronger afternoon breezes from the southwest can be expected each day at that point. Local and typical dust generating activities are the dominant air quality factor. No windblown dust issues or excessive stagnation to note. Low risk.
