Light valley rain and Sierra snow and rain will develop today and
tonight, with some travel impacts possible for Sierra and
northeast California passes. A much stronger system will bring
Lower Valley rain, Sierra rain and snow, and gusty winds starting
on Wednesday and continuing until a cold front moves through late
Thursday into Friday morning.

Impact details Wednesday through friday:

- sierra:

* snow levels will start out fairly high, between 7500 and 8500
feet, Wednesday and Wednesday night before falling Thursday
night into Friday as colder air filters into the region. Several
feet of snowfall are likely in the High Sierra by Friday
morning. Snowfall in the Tahoe basin below 7000 feet, and in
Mono County below 8000 feet, is more uncertain and will depend
on how fast snow levels fall. Still, significant travel impacts
for the main Sierra passes including Interstate 80 and Highway
50 are likely by Thursday, continuing into Friday morning...
with impacts to Highway 395 in Mono County possible by late
Thursday night.

* Strong winds are likely over mountain ridges, with periodic
stronger gusts surfacing in Sierra Valley locations.

- Western and west-central nevada:

* for Wednesday night and Thursday, rain is expected to develop in
the valleys and foothills of western Nevada. A few snowflakes
may mix in with the rain in the foothills by early Friday
morning, but accumulations are unlikely below 5500 feet.

* Winds are expected to be gusty, which could bring periodic
impacts to aviation and high-profile vehicles along with choppy
conditions on area lakes. Currently the two periods of strongest
winds look to be Wednesday and again Thursday afternoon.
