...MULTIPLE WEAK SYSTEMS WILL MOVE ONSHORE OVER THE COMING HOURS TO 
DAYS BRINGING LIGHT PRECIPITATION TO THE FORECAST AREA...

.METEOROLOGICAL CONDITIONS (FRI PM - THU AM)...

No major changes to the afternoon forecast as multiple weak systems 
are forecast to move through the region over the next 6 days. Light 
precipitation continues to spread over the Sierra as the upper low 
moves inland over Baja. A very slight increase was made over the 
Smith Basin for the weekend as a frontal system spreads atmospheric 
river conditions (max IVT ~500 units) to about the I-80 corridor 
(weaker as you go south). The NBM continues to hold onto higher 
accumulations with a system earlier next week, favoring the GFS and 
GEFS, but confidence is still too low to fall into full agreement. 
Adjustments will be made as confidence increases with more guidance 
convergence. With everything in mind, all precipitation is 
relatively light and is currently not forecast to result in any 
major hydrologic impacts.
