Forecast Discussion
Forecast Discussion: Air quality was not too bad at all yesterday. Most of the particulate and ozone network finished the day reporting Good AQI. Those few monitors breaking into the Moderate AQI category were on the lower end. Complimentary air quality trends endure today and likely tomorrow, as well. A changing weather pattern is in progress. The jet stream (fast upper level winds that steer Pacific storms) is cutting through the Great Basin, but buckles later in the week to create a deep low-pressure trough over southern California and Arizona Thursday-Saturday. Strongest winds of the week (20-30 mph) arrive Thursday afternoon when the trough enters the area causing the surface pressure gradient to be tight and maximizing daytime mixing. Some blowing dust and haze is possible, especially for locations where gusty southwesterly winds align with dry dust sources (e.g., the lower Salt River) or are downwind of open deserts. Breezier afternoon winds are in the works even before the main event Thursday because of our proximity to the developing Pacific trough. Consequently, peak daily ozone will struggle to reach higher than the lower Moderates until high-pressure ridging later in the weekend builds causing to winds back down. –J.
