Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 630 AM PST Thu Jan 29 2026 ...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. Please Note: This product may NOT be routinely updated.
