DISCUSSION...  
DRY WEATHER WILL CONTINUE THROUGH FRIDAY.  
 
FOR SATURDAY THROUGH MONDAY, A LOW PRESSURE SYSTEM OFF THE  
PACIFIC NORTHWEST COAST WILL DIRECT SIGNIFICANT PACIFIC MOISTURE  
INLAND ACROSS PORTIONS OF CALIFORNIA. WHILE THE MORE SIGNIFICANT  
RAINFALL IS EXPECTED TO REMAIN NORTH OF POINT CONNECTION, THERE  
COULD BE PERIODS OF LIGHT TO LOCALLY MODERATE RAINFALL AT TIMES  
FOR SATURDAY THROUGH MONDAY. SNOW LEVELS WILL MOSTLY REMAIN ABOVE  
8000 FEET THROUGH SUNDAY, POSSIBLY LOWERING TO 6500 TO 7500 FEET  
ON MONDAY.  
 
FOR LYTLE CREEK, LOCATED ON THE COASTAL SLOPES OF THE SAN GABRIEL  
MOUNTAINS TO THE WEST OF THE CAJON PASS, NBM FOR SATURDAY AND  
SUNDAY HAS A 75 PERCENT CHANCE FOR ONE-TENTH INCH OR MORE OF  
RAINFALL, A 10 PERCENT CHANCE FOR 1.5 INCHES OR MORE, AND A 2  
PERCENT CHANCE FOR 3 INCHES OR MORE. IN GENERAL, REGARDLESS OF HOW  
MUCH RAIN FALLS, MORE IS EXPECTED ON THE COASTAL MOUNTAIN SLOPES  
THAN AT THE COAST WITH MORE NORTH AND LESS SOUTH.
