...DRY CONDITIONS THROUGH THE WEEKEND WITH A CHANCE OF LIGHT PRECIP 
EARLY NEXT WEEK...

.METEOROLOGICAL CONDITIONS (SHORT TERM: TUE PM - FRI AM)...

No short term changes this afternoon, with a continued dry spell 
through the end of the week. High pressure over the eastern Pac 
shifts inland through the week, forming an omega block over the 
western US. Positioned under the ridging portion of the block, 
expect dry conditions to persist until at least Saturday.


.METEOROLOGICAL CONDITIONS (LONG TERM: FRI AM - MON AM)...

Focus is on the late Sunday into early Monday time periods when the 
models bring and offshore s/wv trof to the coast. Both the 25/12Z 
EPS and GEFS show at least light precip across northern CA up into 
southwest OR during this timeframe...and felt comfortable continuing 
to show light precip from the upper Klamath River basin to just 
south of the I-80 corridor across CA. This deviates from WPC 
QPF...which does remain mainly dry through the forecast period.
