Clear skies, light winds and seasonably cool weather persisted through the weekend across Star Valley and surrounding area as an unusually strong and persistent high pressure dominates the Western States.  This high is blocking Pacific storm systems from moving into the U.S.  Instead storms are forced far to the north across Western Canada and then plunging southeastward into the eastern States.  Animation of the water vapor imagery over the weekend clearly depicts this pattern.

 

 

This pattern of High Pressure over the west is forecast to continue much of the coming work week.

 

The models do forecast an upper trough of low pressure to end the long string of  dry skies across Star Valley by this coming weekend.

Through the next 5 days, little if any precipitation is indicated by the models

 

However by next weekend if not by later Friday, some rain and snow will spread across Western Wyoming

Much of the precipitation will be in the form of snow
