Forecast Discussion: Hope you enjoyed the beautiful weekend! Today you can expect cloudy conditions and some light showers through most of the day. We are currently under an upper level ridge, however a cut-off low west of Baja California is moving up the west coast advecting moisture and creating instability over the state. While not a lot of rain is expected, it will still help clear out the air and stabilize soils around the area. Stable soils are great for preventing widespread blowing dust, so PM-10 will be in the Good range for at least the next few days. The conditions today will help with PM-2.5, but there will continue to be potential for Moderate levels and therefore will remain in the Moderate range. Slightly cooler temperatures are expected today, but overall warm temperatures are expected most of the week until a trough late in the week brings cooler temperatures heading into the weekend. Check back tomorrow for more. Until then, have a good day! –R.Nicoll
