DISCUSSION
 
A MILD DAY IS EXPECTED FOR EASTER SUNDAY. STORM #1 SWINGS ACROSS THE  
CENTRAL MOUNTAINS TONIGHT AND EARLY MONDAY. THE STORM TRACK IS FAR  
ENOUGH NORTH AND WITH SOUTHWEST FLOW, MOST OF THE MOISTURE WILL  
FAR NORTH AND WEST OF SUN VALLEY/KETCHUM. THIS PATTERN IS ALSO  
CONDUCIVE FOR HIGHER SNOW LEVELS BETWEEN STANLEY AND SUN VALLEY  
OVERNIGHT. INSTABILITY SHOWERS ARE POSSIBLE THROUGH MONDAY EVENING BEFORE  
THE NEXT SURGE PUSHES THROUGH OVERNIGHT INTO TUESDAY. IT LOOKS LIKE MOST OF  
THE PRECIPITATION WILL FALL WELL SOUTH OF THE CENTRAL MOUNTAINS WITH THIS  
EVENT. SNOW LEVELS REMAIN IN THE 6500-7500FT RANGE.  
 
NOTE: THIS IS THE LAST SAG FORECAST WE ARE ISSUING FOR THE 2016-17  
SEASON. FOR THE LATEST WEATHER INFORMATION, YOU CAN STILL FIND  
IT AT HTTP://WEATHER.GOV/POCATELLO.
