Pacific Jet and Trough impacts will occur
this weekend and lead to significant horizontal air movement, initially
westerly Sat and then northwesterly Sun. Mixing heights will be lowest Sat
then improve Sun but overall mixing will be more than adequate during this
period. The weekend will serve as a clean out event. Showers will also favor
northern and eastern areas. |

Extended Outlook: |
Monday - Wednesday |

|
|
|
|
|
|
|
|
|
|
|
A transition from Troughing to Ridging will occur during
this period and lead to fluctuating mixing heights and transport winds. The
flow will initially be N-NW Mon-Tu and then transition to likely a more
westerly flow on Wed. Transport wind speeds will lower but remain heightened
in areas, especially across the Coastal Mtns, Bay Area and Sacramento Valley.
Ventilation will lower compared to the weekend period but still be more than
adequate to move particulates around most areas. |
