Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 630 AM PDT Wed Jun 10 2026 ...TEMPERATURES INCREASING TO ABOVE NORMAL THROUGH THE PERIOD... ...VERY SCATTERED SHOWERS POSSIBLE FRIDAY INTO THE WEEKEND... .METEOROLOGICAL CONDITIONS (WED AM - TUE AM)... Current setup shows several disturbances rotating through general troffing across the northern Rockies...while a robust area of high pressure continues to strengthen and slowly nudge eastward over the eastern Pacific. This places the region under northwesterly flow aloft. Through the rest of the week...the area of high pressure will make its way closer to the west coast and settle somewhere around 130W. This will bring a period of above normal temperatures to the region with the peak still appearing to occur on Friday with anomalies of plus 5- to plus 20-degF over seasonal normals. This feature will stick around in one form or another into next week with warmer than average temperatures anticipated. Also...models continue to hint at the potential for very scattered convective showers to develop later this week (Friday) and last through the weekend with the best coverage during the afternoon and early evening hours. Look for the southern Sierra...far southern CA...and southern NV to be the location of best chances of this occurring. Freezing levels currently range from 12000-feet northeast to almost 18000-feet southeast along the southern CA coast. Look for slight fluctuations through the period into next week...as the area of high pressure remains the dominant feature along the west coast.
