.SHORT TERM...Tonight through Monday...Low pressure system to the
west will continue to spin up moisture across the area.  The
moisture will be limited to the mountains of northeast Oregon and
the east slopes of the Cascades.  Showers are just now popping up
over the Blue Mountains. Isolated thunderstorms will be possible for
the rest of the afternoon into early evening across northeast
Oregon.  Cooler air will result as well, with highs in the 60s and
in the 50s mountains for the next few days. Lows will be in the mid
30s to mid 40s, with near to below freezing over the mountains. Spot
areas in central Oregon will be in the mid to lower 30s tonight and
tomorrow. Right now some areas could see a freeze, but does not look
like a widespread area of freezing temperatures, and therefore no
freeze warning has been issued.

Precipitation chances will diminish on Saturday as the low dips
south toward Medford.  That will keep most showers along the east
slopes of the Cascades.  As the low centers over Medford on Sunday
there will be some return southerly flow to the central Oregon.
There might be just enough instability combined with upper level
diffluence to get a thunderstorm or two.  Will hold off with just
mention of showers for now.  Weber

.LONG TERM...Monday night through Friday. A storm system will
move into the pacnw Monday night and spread showers to the western
portions of the zones before spreading into the remainder of the
area on Tuesday. The storm system remains nearly stationary over the
two state area and the showers are expected to persist over most of
Oregon/Washington into Wednesday with the exception of the Columbia
basin where a west downslope wind should bring some drying to this
area. As this system slowly vacates the region another will slowly
replace it with increasing clouds and showers spreading west to east
again on Thursday and Friday. Temperatures through the period will
be at or slightly below normal.
