FOR HEAVY SNOW TO DEVELOP IN THE SUN VALLEY AREA NORTHWARDS TO
STANLEY EARLY TUESDAY MORNING. A WINTER STORM WATCH REMAINS IN
EFFECT FOR THAT AREA. THE SITUATION IS LESS CLEAR AFTER THAT. THE
ECM AND UKMET MODELS REMAIN APPOSED TO THE GFS AND TRACK THE

TOWARDS PULLING PRECIPITATION FROM SOUTHEAST IDAHO. HAVE ISSUED A
WINTER STORM WATCH FOR THE CARIBOU HIGHLANDS AND WASATCH

SHARPLY SOUTHWARD. RS
