Weather Conditions:
Sunday, moderate northwesterly winds will disperse pollutants in the Sacramento region. As a result, particle levels will be Good. Monday and Tuesday, a strong upper-level trough of low-pressure moving over northern California will increase vertical mixing in the atmosphere. In addition, onshore flow will effectively disperse pollutants, keeping particle levels Good on both days.
