.PREV DISCUSSION...
SHORT TERM...Today through Monday night...A cutoff low remains
near southern CA, with an extensive cloud shield over OR and
southern ID. This cloud shield has limited radiational cooling
and patchy fog. Expect decreasing clouds later this morning with
sunny breaks in the afternoon. Temperatures will remain mild
with highs around 10-15 degrees above normal through Sunday.
Temperatures in the Snake Plain will be in the low to mid 60s
today and again on Sunday. The upper level trough over southern
CA will move northward into the Great Basin on Sunday. A warm
front with the system will bring rain showers to the area on
Sunday morning before lifting northward in the afternoon. Expect
some partial clearing behind the warm front, with another mild
day on Sunday. Snow levels hover around 9000-10000` with the
warm front. On Sunday evening the center of the trough will move
over southern ID, with wrap around moisture bringing
precipitation to eastern OR and southwest ID early Monday
morning. Snow levels begin to fall to around 6500-7500` on
Monday morning as the system exits. Temperatures on Monday will
be around 5 degrees cooler than Sunday, but still around 5
degrees above normal.

LONG TERM...Tuesday through Saturday...Forecast confidence
remains low in the long term. But still favors seasonable and
unsettled conditions with a series of systems moving into the
Pacific NW. The latest projections bring another system down
the West Coast into another cutoff low off the CA coast by
Tuesday and Wednesday with scattered showers. A brief break
on Wednesday between systems, and then another cut off low
dives south along the West Coast on Thursday and Friday.
