Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 610 AM PDT Wed May 6 2026 ...DRY WITH ABOVE NORMAL TEMPERATURES INTO EARLY NEXT WEEK... .METEOROLOGICAL CONDITIONS (WED AM - TUE AM)... The slow moving upr low that traversed the region early this week has finally moved off downstream of the area...while also leaving an a piece of this disturbance in a compact upr low over northwest Mexico. At the same time an upr ridge has built just off the west coast...which has resulted in dry northerly flow across the region. Through the rest of the week...the upr ridge will slowly build over the west coast...bringing dry conditions and warming temperatures. A weak disturbance will briefly flatten the upr ridge on Friday as it moves across the Pacific Northwest...but this feature is expected to have little impact on conditions across CA and NV. The peak of the upcoming upr ridge will be on Monday or Tuesday as afternoon high temperatures are expected to peak anywhere from plus 10- to plus 20-degF over seasonal normals...with a few locations over the northern Sierra and northwest NV reaching an anomaly of plus 25-degF. Freezing levels currently between 10500- and 12500-feet...greatest over northwest CA will increase through the weekend into early next week and peak somewhere between 13500- and 15500-feet on Monday.
