.DISCUSSION...

A high-pressure ridge off the California coast building into the
northern Great Basin and a developing low off Southern California
will bring easterly breezes on Thursday (gusts 15-25 mph
generally, 40-50 mph on ridge tops, and up to 60 mph overnight).
Lake Tahoe`s western shores may see choppy waters Thursday night.
As a result, a Lake Wind Advisory is in place for Lake Tahoe from
7 PM thursday through 2 AM on Friday.

By Friday, winds shift to the southeast with afternoon gusts of 15-
25 mph, with localized areas up to 30 mph. Lower humidity
(12-20%) will elevate fire weather concerns in these areas. See
the Fire Weather Discussion for more details.

Winds diminish Saturday, returning to typical southwest/west breezes
Sunday. Temperatures will rise into the mid-to-upper 70s for lower
elevations and near 70 degrees in the Sierra.

An approaching upper-level trough breaks down the ridge early next
week. Monday brings increasing winds with 30-40 mph gusts and
renewed fire weather concerns.

Cooler temperatures in the 50s to lower 60s follow Tuesday through
Thursday. Showers are expected Tuesday night through Thursday (30-
50% chance south of US-50, 15-30% elsewhere), with light rain in
valleys and snow above 8000-8500 feet in Mono County.  HRICH
