Hydrometeorological Discussion National Weather Service / California Nevada RFC / Sacramento CA 130 PM PDT Wed Apr 1 2026 ...ONGOING PRECIPITATION WITH SYSTEM DEPARTING OUT OF THE SOUTH AND SYSTEM MOVING IN ACROSS THE NORTH... ...RETURN TO WARM AND DRY WEATHER BEGINNING FRIDAY AND INTO EARLY NEXT WEEK... .METEOROLOGICAL CONDITIONS (WED PM - TUE AM)... No changes from the morning forecast as the frontal system continues to trek down the northern California coast, spreading precipitation inland to the central Sierra. Freezing levels throughout the remainder of this event into Thursday will begin the period around 5.5k feet across the North Coast and 7.5k feet across the southern Sierra before lower under the digging trough/front to ~3k feet along the North Coast, 6k feet around the I- 80 corridor, and remaining around 7.5k feet over the southern Sierra. Once this systems departs the region, ridging is forecast to rebuild across the western U.S. into the weekend. This will lead to anomalous 500-hPa heights of 2+ sigma over the Pacific Northwest by Sunday and a return to hot and dry weather across the forecast area. This mornings GFS deterministic hinted at the potential for a weak system moving in on Tuesday, but model-to-model spread keeps this event unlikely (for now). |
