...MAINLY DRY CONDITIONS THROUGH THE PERIOD...
...TEMPERATURES BOUNCING AROUND NORMAL THROUGH THE UPCOMING WEEK...

.METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)...

With upr troffing downstream over the Great Plains...an upr ridge
offshore centered close to 30N/140W...and low pressure residing over
the Gulf of Alaska...the region sits under west to northwest flow
aloft. This will begin a mainly dry period for CA and NV...as the
storm track remains primarily over BC and the Pacific Northwest. The
southern extent of a couple of these disturbances will reach close
enough to the CA/OR border area to generate some light precip for
the crest of the southern OR Cascades and maybe the Smith River
basin in extreme northwest CA on Monday and to a lesser extent on
Tuesday/Wednesday.

This pattern will remain fairly persistent through the work week
before the upr ridge sharpens a bit and shifts toward the west coast
on Friday into Saturday before moving inland and an upr low takes up
residence over the northeast Pacific. Right now...models show
differences in the strength of the system...and opportunity for
precip across the region beyond the forecast period. Temperatures
will fluctuate around normal through the week as each disturbance
moves through BC and the Pacific Northwest.
