Special Weather Statement
... Change to an active weather pattern for next week and the
Thanksgiving weekend...
Two areas of low pressure will affect the region this week. The
first arrives Tuesday and the second by late Thanksgiving day into
early Friday.
Rain and snow with the first system is forecast to reach the
central Sierra on Tuesday and spread into western Nevada on
Tuesday night and Wednesday as the low moves onshore. This system
will bring down snow levels to 5500 to 6000 feet across the
region for Tuesday night and Wednesday. There is potential for
significant snow accumulations in the Sierra south of Lake Tahoe
to Mammoth Lakes.
The track of the second system remains quite uncertain as it drops
out of the Gulf of Alaska. Forecast models are indicating this
system could move south along the Sierra or remain just off the
California coast. However confidence that the storm will affect the
area late Thanksgiving day or early Friday is increasing. Forecast
models indicate the system may linger over the region into Saturday...
with cold and moist conditions. Snow levels may drop below 5000
feet if the storm moves south along the Sierra while snow levels
would be higher if the system remains offshore. The most likely
time frame for potential significant snows in the Sierra is from late
Thanksgiving day into Friday. Light accumulations may be possible
for elevations below 5500 feet... including portions of western
Nevada.
If you have travel plans for the Thanksgiving Holiday in the
Sierra and western Nevada... be prepared for winter driving
conditions. Check our website at www.Weather.Gov/Reno for updates

Rain and snow with the first system is forecast to reach the
central Sierra on Tuesday and spread into western Nevada on
Tuesday night and Wednesday as the low moves onshore. This system
will lower snow levels to 5500 to 6000 feet across the region for
Tuesday night and Wednesday. Computer models are showing abundant
moisture in the central Sierra with this system. This will create
the potential for significant snow accumulations in the Sierra
south of Lake Tahoe to Mammoth Lakes.
The track of the second system remains uncertain as it drops out
of the Gulf of Alaska. However confidence for the storm to reach
the area Thanksgiving day is increasing. Models have shown the
system may remain over the area Friday and Saturday... with cold
and moist conditions. Snow levels may drop as low as 4500 feet if
the storm passes overhead. The most likely time frame for
significant snow in the Sierra with this storm is Thanksgiving day
into Friday. Light accumulations may be possible for elevations
below 5500 feet... including portions of western Nevada.
