Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 830 AM PDT Wed Mar 11 2026 ...POTENTIAL SHOWER ACTIVITY OVER FAR NORTH WITH WEAKENING SYSTEM CLIPPING THE REGION... ...ANOMALOUS RIDGE TO CONTINUE BUILDING THROUGH WEEKEND PRODUCING MORE DRY AND WARM WEATHER... .METEOROLOGICAL CONDITIONS (WED AM - TUE AM)... High pressure will continue to keep a majority of the forecast area dry throughout the six day window with the only chance for precipitation over northern Humboldt and Del Norte counties along with the southern Oregon Cascades as weakening systems clip the northern regions on Friday into Saturday. The ridge that is directing atmospheric river activity towards the Pacific Northwest will continue continue to build throughout the rest of the weekend placing a 2+ sigma 500-hPa height anomaly over northern and central California early next week. This will continue the dry weather streak and produce potentially record breaking afternoon high temperatures. Freezing levels are forecast to rise to above 14k feet by early next week, reaching above 16k feet over the southeastern deserts on Tuesday. Afternoon high temperatures in the highest elevations of the Sierra Nevada may reach 60F+ in the north and 50F+ in the southern High Sierra. Please Note: This product may NOT be routinely updated.
