...STRONG WINDS THIS WEEKEND WITH SNOW OVER THE PASSES BY LATE
A potent Pacific storm will move inland this weekend and bring
rain, mountain snow and gusty winds. The winds will begin Saturday
afternoon and continue through Sunday night. Precipitation will
begin as rain, even at the passes, as snow levels start high.
Snow levels will begin to fall Sunday with snow over the passes
possible by sunset Sunday. Expect holiday weekend travel impacts
due to winds and snow over the passes. Some details follow:
* WINDS: Strong, gusty southwest winds are expected both Saturday
and Sunday afternoons. Winds may abate some overnight Saturday
night in some valley locations, but they will remain strong over
the ridges. While it is too early to estimate peak gusts, gusts
of 60 mph or more are possible along portions of the 395
corridor and Sierra ridge gusts will likely exceed 100 mph.
* PRECIPITATION: Light rain is likely over the mountains by
Saturday evening north of I-80, gradually spread southward into
Sunday evening. Snow levels will also gradually fall during this
time before crashing late Sunday night as a strong cold front
moves through. The precipitation will end Monday morning behind
* SNOW LEVELS: Starting at near 9000 feet Saturday afternoon. They
will fall to 5500 feet for Lassen County, 7000 feet for the
Tahoe Basin, and 8000 feet for Mono County by late Sunday
afternoon. Snow levels will crash Sunday night and fall to near
the lower valley floors as the precipitation ends. While it is
too early to predict snowfall amounts, accumulations are likely
for the Sierra passes with light accumulations possible as low
as 5000 feet. Be prepared for major travel delays over Sierra
passes due to slick and snow-covered roads.
