Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 630 AM PDT Thu Jun 25 2026 ...COOLER WITH PRECIP CHANCES INCREASE NORTH OF I-80 FRI-SUN... .METEOROLOGICAL CONDITIONS (THU AM - WED AM)... Weak troffing along the west coast will be reinforced by an area of low pressure dropping southeast from the Gulf of Alaska toward the region tomorrow and persisting through the upcoming weekend as individual disturbances rotate around the cyclonic flow. Chances of precip will increase late Thursday or early Friday mainly for areas north of I-80 and over the higher terrain. This will continue into Saturday and Sunday as the overall flow regime remains similar...before finally weakening Monday into Tuesday. Freezing levels currently from 13000- to 16000-feet will bottom out late Saturday into early Sunday from 7000-feet north with a sharp gradient over the central portion of the region and 17000-feet far south. These will rebound up north by the middle of next week closer to 11000-feet. Please Note: This product may NOT be routinely updated.
