000 feet.

...Tuesday through Saturday...

A brief lull in activity is possible Tuesday morning before we
start to see snow levels drop and precipitation become moderate
to heavy once again. Surging moisture and instability from the
Pacific brings widespread rain, higher elevation snow, and travel
impacts to the area Tuesday through Friday. Snow levels begin to
drop toward 5500 feet late Tuesday and into Wednesday. During this
time, winds will be increasing out of the south once again, with
gusts up to 55mph possible for both Wednesday and into Thursday.
Higher winds combined with heavy snow bring travel impacts within
the mountains during the holiday period. Snowfall 5500-6500 feet
will be up to a foot while areas above 6500 feet will see 3-6 feet
with locally higher amounts at higher elevations.

Rain will be moderate to heavy at times, with flooding in
susceptible urban and low lying areas, including small streams
and creeks. Areas that see thunderstorm activity may see rainfall
rates up to an inch per hour. A flood watch is in effect through
Friday for the flooding potential. Rockslides, mudslides in the
foothills/mountains will be likely. Rainfall will range between
3-8 inches from today through the end of the holiday week for
areas within the Valley, with over 10 inches within potions of the
Sierra north of I-80. If you have travel plans this week plan
ahead, make alternate routes, have backup plans, and carry safety
kits with you in case of an emergency. If you see flooded areas,
turn around don`t drown.

There will be a chance for lingering impacts Friday and into the
early part of the weekend, especially up in the mountains where
high snowfall is likely. Areas in the valley will see improving
conditions, and later the mountains as the synoptic setup aloft
shifts the main track of systems toward the Pacific NW.
