.SHORT TERM...
Issued at 122 PM PST Sun Feb 22 2026
(This evening through Monday)

Not much change from the prior forecast, as the first round of rain
showers traverse cross the North Bay. Rainfall amounts so far, as of
12:30pm range from 0.0-0.17" for the valleys of Sonoma County and
between 0.15-0.55" for the mountains with the higher amounts being
found across the coastal side. Showers will linger through at least
the evening hours, before lifting north into Eureka`s service area
overnight hours. Showers may skirt by the North Bay on Monday, but
the more likely scenario is that rain holds off until late Monday
evening or into the overnight hours. That means much of the region
will be left with partly to mostly cloudy skies and temperatures in
the 60s for most of the region, perhaps the low 70s for the valleys
of the South Bay and interior Central Coast.

.LONG TERM...
Issued at 122 PM PST Sun Feb 22 2026
(Monday night through next Saturday)

The bulk of the rain will arrive on Tuesday, as a surface low sets
up and taps into moisture from the southwest/tropics. This will
bring periods of rain and gusty winds on Tuesday, with chances for
rain dwindling late Tuesday night into Wednesday morning. PWATs
across the region look to be between 1.2-1.4", which combined with
orographic lift may lead to some heavier bands of rain and nuisance
flooding across the North Bay or San Francisco Peninsula and into
the Santa Cruz Mountains. Valleys may be rainshadow a bit in these
regions, with rainfall amounts decreasing as you move south and into
the Central Coast. In terms of thunderstorm chances, they look to be
null as CAPE is either extremely low or zero depending on the model,
and lapse rates are stable.

As we begin to dry out on Wednesday, upper level ridging builds in
from the south and will take hold of the forecast. A warming and
drying trend begins on Thursday and continues into the weekend.
Ensembles show ridging holding, but a low developing in the Eastern
Pacific, perhaps trying skirt over or push it eastward by the
beginning of March. PoP chances are low, but still reflect that non
zero, more like 10-20% chance of rain. The CPC outlook for this
period favors the drier scenario with leaning below normal (33-50%)
chances for rain and likely above normal (60-80%) chances for above
normal temperatures.
