228 AGUS76 KRSA 141310 HMDRSA Hydrometeorological Discussion National Weather Service / California-Nevada RFC / Sacramento CA 610 AM PDT Mon Sep 14 2026 ...SCATTERED PRECIP MAINLY NEAR CA/OR BORDER WED INTO THU... ...COOLER THAN NORMAL TEMPS WILL WARM BY THIS WEEKEND... .METEOROLOGICAL CONDITIONS (MON AM - SUN AM)... General troffing exists along the west coast this morning as the s/wv trof from this weekend moving across the Pacific Northwest and far northern CA slowly makes its way toward the northern Rockies. As this occurs...another disturbance currently over the Gulf of Alaska is anticipated to dive down the AK and BC coast before settling over northern CA by the middle of the week. This will bring an increased chance of showers mainly Wednesday and Thursday to the upper Klamath River basin and possibly down toward the Shasta Lake drainage and Trinity Alps. Not a lot of moisture entrained into this system...and as a result...amounts should be limited to 0.25-inch or less. For the end of the week...this slow moving system will pick up its forward speed and begin to shift off toward the northeast...reaching the northern Rockies by later Friday into Saturday...while high pressure over the eastern Pacific begins to build toward the west coast. This will bring warmer and drier conditions to the region. Please Note: This product may NOT be routinely updated.
