RIDGE OF HIGH PRESSURE. OVERNIGHT LOWS WILL CONTINUE TO BE ON THE  
COOL SIDE HELPING TO BRING LOW AFTERNOON MIXING HEIGHTS AS THIS  
UPPER RIDGE PARKS OVER THE WEST COAST. THE NEXT UPPER LOW WILL BRING  
A CHANCE OF RAIN AND SNOW SHOWERS LATE SUNDAY NIGHT THROUGH MONDAY.  
A HIGH AMPLITUDE RIDGE WILL BUILD IN BEHIND THE EXITING TROUGH AND  
BRING UNSEASONABLE WARM TEMPERATURES AND DRY CONDITIONS FOR THE
