...NEXT WINTER SYSTEM ARRIVES TODAY: MORE SIERRA TRAVEL IMPACTS
EXPECTED, RAIN CHANGING TO SNOW THIS EVENING ON VALLEY FLOORS...
RAIN/SNOW: Initial wave of moisture arrives over the Sierra this
morning with rain and snow spilling into western Nevada by mid to
late morning. Snow levels will start off near valley floors but
will be rising to between 5000 and 6500 feet during the afternoon.
The main window to see snow impacts in the valleys will begin
this evening as snow levels quickly drop to most valley floors
behind a cold front. An inch or two of snowfall is possible for
the lower elevations in the I-80 and Highway 50 corridors with
about a 20% chance of seeing 2 to 4 inches for the North Valleys
of Reno, Virginia City, and foothill areas. Up to 3 inches will
be possible along Highway 395 communities through Mono County,
with 3 to 8 inches in Mammoth Lakes.
Snow is expected to taper quickly before daybreak Monday, but
roads may remain slick and hazardous with potentially longer
commute times on Monday morning.
A Winter Weather Advisory remains in effect across the east side
of the northern Sierra and northeast California through Monday
morning. Travel impacts with chain or snow tire restrictions are
likely with hazardous road conditions potentially continuing to
impact the Monday morning commute. See the winter statements for
more information in those areas.
WIND: This system will provide another round of gusty winds this
afternoon with Sierra ridgetop winds increasing through the day
with gusts between 70 and 100 mph by early afternoon. Although
not a big wind producer, wind gusts will generally be in the 30-40
mph range. Wind prone areas along Highway 395 through the North
Valleys, Washoe Valley, Carson Valley, and Mono County could see
localized higher gusts to around 50 mph.
