Upper
level troughing over the area will support active smoke dispersion conditions
through the weekend though which will still likely be overwhelmed by the
smoke production from the ongoing large fires. Smoke transport winds will
mainly be out of the south to southwest and strengthen during the afternoons
& evening accompanied by gusty S-SE to W-SW surface winds favoring
coastal gaps and eastern areas with breezy afternoon & evening winds
continuing elsewhere and an increase in SE winds along the east side of the
Sac Vly and lower Cascade/Sierra west slopes this evening into Sat morning.
Mixing heights will be moderate to good during the afternoons and evenings
with the best mixing heights favoring the N & E. Smoke will accumulate in
fairly typical valley inversions during the overnight through morning hours. |

Troughing
and breezy afternoon and evening SW to W-NW winds will continue on Mon
keeping smoke dispersion conditions active through early next week. Upper
level ridging will begin building to the east on Tue then strengthen overhead
mid to late week bringing a return to hotter and drier conditions with
worsening overnight RH recoveries. Smoke dispersion conditions will decrease
in response with strengthening thermal belts further leading to the
accumulation of smoke over the area. Smoke transport winds will continue to
be out of the SW but will decrease in response to the strengthening ridge as
the week progresses. |
