Discussion:
Dispersion will peak today due to the combination of strengthening transport wind and higher mixing heights. Transport winds will remain strong across the north and lead to better dispersion results there, otherwise dispersion will be much lower thanks to lowering mixing heights. Precipitation will also be likely most areas favoring later today and tonight and aid in cleansing the atmosphere of particulates.

Extended Outlook:
Sunday through Tuesday:  Strong high pressure will start to develop Sunday and last into early next week. This will result in a stable layer aloft and lower mixing heights. Surface temperatures, however will be 10-15 degrees above normal. Transport winds will also be fairly light except near the surface within the Sacramento Valley due to strengthening northerly winds. Dispersion overall will be on the lower side during this period.
