DISCUSSION...  
DRY WEATHER WILL CONTINUE THROUGH FRIDAY.  
 
A LOW PRESSURE SYSTEM OFF THE PACIFIC NORTHWEST COAST WILL  
CONTINUE TO DIRECT SUBSTANTIAL PACIFIC MOISTURE INLAND ACROSS  
PORTIONS OF CALIFORNIA THROUGH MONDAY WITH THE MOST SIGNIFICANT  
MOISTURE AND RAINFALL FROM AROUND THE BAY AREA NORTHWARD AND WITH  
MOISTURE AND LIGHTER RAINFALL DECREASING RAPIDLY TO THE SOUTH AND  
EAST OF LOS ANGELES. SNOW LEVELS WILL MOSTLY REMAIN ABOVE 8000  
FEET THROUGH MONDAY. LESSER CHANCES FOR PRECIPITATION WILL  
CONTINUE THROUGH MUCH OF NEXT WEEK, BUT WITH INCREASING SPREAD IN  
THE DETAILS.
