Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 1220 PM PDT Thu Mar 12 2026 ...MAINLY DRY WITH WELL ABOVE NORMAL TEMPERATURES NEXT WEEK... .METEOROLOGICAL CONDITIONS (THU PM - WED AM)... The weather story for the next 7 to 10 days will be the incoming area of high pressure and resulting well above normal temperatures expected across the region...and in some cases setting all-time March record highs. The warm temperatures look to peak sometime between Tuesday March 17 and Thursday March 19 as the area of high pressure slides inland from along the California coast over the interior of the Pacific Southwest. Afternoon high temperature anomalies will most likely range from plus 15- to plus 30-degF over seasonal normals. In terms of precip...the only opportunity will be Friday into Saturday as a moisture plume and cold front moving across the Pacific Northwest begins to sag south with an approaching s/wv trof to the west coast near the Canada/US border. Light precip is possible over the Smith River basin and inland across the crest of the southern Oregon Cascades with 0.10- to 0.50-inch possible...greatest near Crater Lake. Otherwise...look for dry conditions to persist across the region. Freezing levels will start the period from 9000-feet over the far north and 14500-feet south...and then really ramp up into next week. By Tuesday...look for freezing levels of 14000- to 16500-feet across the entire region. |
