.METEOROLOGICAL CONDITIONS (TUE AM - MON AM)...

High pressure continues to dominate conditions across the eastern
Pacific and west coast with the storm track focused well north of
the area into British Columbia. This will continue to bring above
normal temperatures for the next few days with anomalies of plus 5-
to plus 20-degF during the afternoon hours. Also...with just enough
moisture and instability from daytime heating...the potential exists
for afternoon showers and t-storms to develop mainly over the crest
of the Sierra with the best opportunity south of Lake Tahoe. Might
also see some popup showers over the coastal mountains east of San
Diego and portions of east-central NV.

Finally...by the end of the week...the pattern will break with the
upr ridge being pushed downstream of the area toward the Rocky
Mountains and eventually the Great Plains. General troffing will
setup along the west coast with cooler temperatures and an
increasing chance of showers and t-storms on Friday into Saturday
over the upper Klamath River basin down into northeast CA stretching
down the northern/central Sierra and farther inland across much of
northern NV. Amounts should average near or less than 0.25-inch with
the potential for locally heavier totals under stronger cells. After
this disturbance moves off to the east...look for slight
anticyclonic flow to return to the west coast with temperatures
rebounding above normal.

Freezing levels through Thursday will generally range from 15000- to
17000-feet with some lowering this weekend (especially north) from
around 13000- to 17000-feet...before jumping by approx 1000-feet by
early next week.
