Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 610 AM PDT Thu Jul 9 2026 ...INCREASING CHANCE OF SCATTERED SHOWERS/T-STORMS SUN-TUE... .METEOROLOGICAL CONDITIONS (THU AM - WED AM)... Just enough moisture and instability over northeast NV yesterday generated scattered showers and thunderstorms mainly during the afternoon and early evening hours primarily impacting Elko County. The overall profile in this area shows just a tad less available moisture (0.61-inch PW at 09/00Z) today with the majority residing in the mid-levels of the atmosphere and a rather dry sub-cloud layer. Overall...look for scattered showers and thunderstorms to once again develop once again over northeast NV. The next couple days then look dry as the high pressure residing over southern CA begins to strengthen and move off toward the northeast...crossing the 4-Corners region and then expanding over the Rocky Mountain and Plains states. Flow across CA and NV will turn more southeast to south...drawing moisture from northwest Mexico toward the region. PW values will most likely be at or above 1.00-inch for much of the area with peak with an increasing chance of showers and thunderstorms from Sunday into the middle of next week. Best chances look to be over the central/southern Sierra stretching eastward over the majority of NV...and portions of southern CA. Freezing levels are currently running anywhere from 14500-feet north to 17500-feet south. These will peak later Friday with a broader area of 16000-feet plus for freezing levels. Into next week...the gradient becomes a bit more west to east with 14500-feet along the north coast to 17000-feet along the UT/NV border. Please Note: This product may NOT be routinely updated.
