Discussion
This week, several low-pressure disturbances will pass through the region and result in periods of breezy winds in central Arizona. The breezy periods are this morning, Thursday afternoon, and Saturday afternoon. As for the air quality, dust is expected from the winds, given how dry it has been. For example, last night around midnight, Casa Grande saw really high PM10 (dust) levels.
For now, the dust risk is Moderate, but we'll re-evaluate if the risk should be increased on the windier days this week.
