How Much Longer Before Return to Winter in Star Valley?

How Much Longer Before Return to Winter in Star Valley?

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.
