Issued:

12:30 PM   Friday, November 07, 2025

Discussion - Saturday & Sunday

Upper level ridging moving in from the west tonight and remaining overhead as it continues to strengthen Sat & Sun will bring warmer & drier conditions to North Ops with overall lighter general winds and decreasing smoke dispersion conditions. Locally breezy N-NW to NE winds will develop tonight and continue into Sat morning favoring western portions of the Sac Vly and channeled terrain areas along the Cascade/Sierra west slopes before diminishing midday with light terrain driven winds Sat afternoon. More limited and generally lighter NE winds along ridges and through channeled terrain areas with SE winds along NE ridges will develop Sat night through Sun morning before diminishing again with light terrain driven winds Sun afternoon. Moderate to strong valley overnight through morning inversions will develop both nights with the influence of the ridge overhead limiting vertical mixing during the afternoons.

Extended Outlook:

Monday - Wednesday

Smoke dispersion conditions will remain limited Mon & Tue as the upper level ridge remains centered overhead. Surface and transport winds will remain light and terrain driven with persistent overnight through morning valley inversions. Troughing deepening offshore on Wed will begin returning SW flow aloft to North Ops with breezy SE winds beginning to develop in western portions of the areas. Smoke dispersion conditions will begin gradually improving as a result but depending on the timing and strength of the frontal system may remain somewhat limited until late week when the trough and an accompanying frontal system move onshore.
