Extended Outlook:

Saturday - Monday

Ridge should remain impactful during the weekend as a offshore Low forms and draws closer to the region. Transport wind flow should gradually increase and become W-SW-S, especially by early next week. Ventilation will remain on the lower side across western-central areas and a little better across the E. Best improvement comes Monday at this time.
