Special Statement
Issued: 4:18 AM PST Nov. 20, 2018 – National Weather Service

... Major change to winter weather forecast for the Holiday
weekend...

A major change in the weather pattern is coming to norcal this
week impacting Holiday travel. A series of winter like storms
will plow through norcal bringing rain and mountain snow to the
region. The first system is set to arrive late Tuesday night
pushing through the north state Wednesday and Wednesday night.
Another system will move though late Thursday and Thursday night
with one last system pushing through on Friday.

Snowfall over the Sierra and debris flow over the recent norcal
fires are a major concern with these weather systems and hazard
watches have been issued for these impacts.

This change in the weather pattern will bring other impacts as
well. The accumulation of dirt and oils on the roadways will
produce very slick conditions especially early on in this wet
period Tuesday night and Wednesday. The Wednesday evening commute
and Thanksgiving travel period will likely see increased traffic
accidents due to the slick roadways and motorists should use extra
caution. As rainfall accumulates over the Holiday weekend,
ponding water will be possible where storm drains have been
clogged by leaves and other debris. In addition to the rainfall,
the weather system passing through norcal late Thursday will bring
gusty south winds. The northern Sacramento Valley could see wind
gusts up to 40 or 45 mph with gusts to over 60 mph over the higher
Sierra. Downed tree limbs, blowing objects, and difficult driving
will be a concern during this late Thursday through Friday time
period. Use extra care while traveling this Holiday weekend as
many weather related hazards will be present that have not been a
concern for the last several months.

Conditions will begin to improve on Sunday with a return to drier
weather expected early next week.
