.DISCUSSION...Satellite image shows the upper trough just east of
the Cascades. On the backside of the upper low, a thinker cloud
layer is moving in from the north along with enhanced steadier
precipitation. Light steady rain is being reported in Eugene,
Roseburg, and along the coast north of Cape Blanco. The high res
short range models show the steadier precipitation moving from north
to south during the afternoon and they have been showing this trend
the past couple of runs. Precipitation will increase in the
afternoon and lasting into this evening, and mainly concentrated
along and west of the Cascades.

Light to occasionally moderate precipitation will continue into this
evening, then gradually diminishing overnight tonight. However there
are indications light rain could be persistent north of the Umpqua
Divide and northern Cascades overnight tonight.

The general consensus suggest ample cloud cover will remain tonight.
There could be brief periods of clearing since were not expecting
overcast skies, and this should slow down the amount of cooling
during the overnight period. A few locations east of the Cascades
could get towards freezing for an hour ot two towards daybreak
Sunday.

Sunday, any showers will be isolated and ending towards mid morning
with dry weather likely for the afternoon. Clouds will also
gradually diminish with partly cloudy skies by the afternoon.
Afternoon temperature Sunday will rebound and will be warmer for the
interior.

Clouds are expected to diminish Sunday evening with mostly clear
skies Sunday night. However, there will be warming aloft and
guidance suggest areas between Chemult and Crescent are at highest
risk of getting near freezing towards daybreak Monday.

The upcoming work week is expected to be dry with warmer
temperatures for the interior. While afternoon temperatures will be
above normal, were not expecting hot temperatures. For example, high
temperatures for interior westside valleys will be in the mid to
upper 80s to near 90, except for slight cooling Wednesday and
Thursday.

The clusters and ensemble mens suggest upper ridging building into
the area towards the start of next weekend. It will be at this point
where we could have afternoon temperatures in the low to mid 90s for
the interior westside valleys and upper 80s east of the Cascades.
