Forecast Discussion: OZONE (O3): Local 8-hour ozone concentrations were in the moderate range of the Air Quality Index for the third straight day on Tuesday with hot afternoon temperatures, mostly light winds, and no cloud cover all probable factors. In addition, the wind-flow below 10K’ has become conducive to occasional influxes of additional ozone and/or its precursors from the northwest and this is now being projected to continue thru this forecast period. As a result forecast ozone levels in the low to mid-moderate range of the Air Quality Index range will continue. COARSE PARTICLES (PM-10): A fairly significant upper level trough will be over the western U.S. into the upcoming weekend. Even so, for the Yuma area relatively weak low gradients are should yield afternoon winds mostly in the 5-15 mph range. Since the risk for blowing dust is expected to be low local PM-10 (coarse particle) concentrations are forecast to remain within the good range of the Air Quality Index. |
