Forecast Discussion:

This morning, there are plenty of clouds across the region as a trough moves through the Western United States, coupled with another weak disturbance moving through the southern portion of California. While we are not expecting any rain out of these clouds, as the system moves through today, there will be an increase in south-southwest winds in the 10-15mph range. The system will also usher in some cooler air, with afternoon high temperatures tomorrow dropping back into the upper 60s.

As the system moves east tomorrow, high pressure will quickly move back into the region, resulting in lighter winds and a warming trend through Thursday.

By Thursday, a trough will move into the Pacific Northwest, with the tail-end moving through Arizona on Friday. This may bring some more clouds to the region late Thursday, along with some breezes, but right now, expecting all rain chances to stay north of the area.

As for air quality, with cold mornings, mainly light winds, strong inversions, and the likelihood of more fireplaces/firepits being used this weekend as people get in the holiday spirit, PM-2.5 was elevated Friday through the weekend. The good news, values are already running lower this morning; however, they are still forecast to be in the Moderate AQI through the forecast period, just not in the upper Moderate AQI category.

Have a great Monday!
