...MAINLY DRY INTO NEXT WEEK...
...ONLY PRECIP OPPORTUNITY ALONG THE IMMEDIATE NORTH COAST ON SUN...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

The s/wv trof from later Tuesday into Wednesday has quickly moved 
well downstream of the area...now crossing the central Plains. In 
its wake...a positively tilted upr ridge is now building across the 
western US and extending well into western Canada. This will divert 
the next moisture plume advecting from the lower latitudes near 
Hawaii to Vancouver Island...keeping precip well north of the area 
on Thursday. A s/wv trof making its way through this upr ridge will 
briefly flatten the feature as it crosses southern BC on 
Friday...pushing the moisture down across the Pacific Northwest. It 
is still looking like precip will remain north of the area reaching 
the central/southern OR coast.

For the upcoming weekend...the upr ridge will re-establish itself 
just a touch inland as compared to today...which will allow a s/wv 
trof rotating around an upr low making its way from the central 
Pacific toward the Gulf of Alaska to cross the Pacific Northwest and 
clip far northwest CA on Sunday. This will bring some rather light 
precip to the immediate coast from about Point Arena northward to 
the CA/OR border with a few hundredths of an inch for most locations 
to 0.10- to 0.25-inch over the King Range and 0.25- to 0.33-inch for 
the Smith River basin. Otherwise...the region will remain dry.

For next week...the upr ridge along the west coast will once again 
pump up and extend into western Canada. This will bring another week 
of mainly dry conditions. Also...looking at the CPC 8-to-14 Day 
Outlook for Feb 5-11...look for a slightly higher likelihood (40- to 
50-percent) of below normal precip across the entire west coast. The 
month of February is definitely not looking promising to turn the 
tide on this prolonged drier below normal precip stretch.
