The National Weather Service (NWS) reports that a notable pattern change is on the horizon for Central California as a robust upper-level trough, currently situated in the Gulf of Alaska, is expected to deepen southward along the Pacific coast by midweek.
The orientation of the system is predicted to usher in increased moisture from the south to southwest, initiating Wednesday evening and persisting through Saturday.
The entrainment of moisture from this system is forecasted to result in another round of substantial precipitation across the Central California area.
Projections indicate storm totals ranging from 0.75 to 1.50 inches through the San Joaquin Valley, Tehachapi Mountains, foothills of the Sierra Nevada, and the Coastal Range. In the Kern County Desert, totals are expected to be closer to 0.50 inches.
Snow levels associated with this approaching system are anticipated to commence around 7,000 feet on Wednesday, gradually lowering to 4,000 feet into the latter part of the week.
