Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 605 AM PDT Fri Jul 31 2026 ...DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES INTO NEXT WEEK... .METEOROLOGICAL CONDITIONS (FRI AM - THU AM)... High pressure is centered over the vicinity of the 4-Corners region and has expanded its reach westward over CA and NV this morning. At the same time...general troffing exists over the northeast Pacific extending from an upr low spinning near 50N/140W. Through the weekend...the area of high pressure will strengthen and reach near 6000-meters at 500-mb while also drifting just a tad to the west. Over the northeast Pacific...the offshore low pressure system will rotate inland across BC and the Pacific Northwest...which may help keep temperatures in check just a bit over the far northern portion of the area on Sunday and Monday. Then for much of next week...the area of high pressure will continue to meander near the 4-Corners region...while a weaker disturbance moves toward Vancouver Island on Wednesday. This s/wv trof doesn/t look to have much impact on the area. Overall...through the upcoming week...expect temperatures to fluctuate anywhere from plus 5- to plus 15-degF over seasonal normals...except the immediate coast where marine influences will keep temperatures closer to average for this time of year. Freezing levels currently running anywhere from 15000-feet near Crater Lake to 18500-feet near Point Conception will stay in this general range through much of the upcoming week.
