Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 725 AM PDT Sun Jun 28 2026 ...COOLER WEATHER MODERATING A BIT THROUGH THE WEEK... ...BEST CHANCE SHOWERS TODAY ACROSS NE NEVADA... .METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)... Broad upr trof continues to sit across the western US...while upstream is a strong area of high pressure centered over the eastern Pacific. This places much of the region under west to northwest flow aloft with cooler than normal temperatures on tap...bottoming out today and moderating a bit through the week. High temperatures today will run anywhere from 5- to 25-degF under seasonal normals with the greatest anomalies over northern NV. Best opportunity for precip through the week will be today over the Humboldt River basin in northeast NV. Then as the troffing weakens a bit by midweek and toward the 4th of July weekend...precip chances diminish with only some very scattered showers possible across northeast NV. Freezing levels are currently running around 7000-feet over the upper Klamath River basin down to northeast CA and northwest NV. Down near the CA/MX border...freezing levels are near 17000-feet. As the upr trof weakens a bit look for the freezing level to bump up a bit across northern areas...closer to 12500-feet...and remaining about 17000-feet near the CA/MX border.
