Factors Influencing Snoqualmie Pass Weather

Several factors contribute to the unique weather patterns in Snoqualmie Pass:

• Elevation: The pass sits at an elevation of over 3,000 feet (914 meters), which means it experiences colder temperatures and more precipitation than lower-lying areas.

• Cascade Mountain Range: The mountains act as a barrier, forcing air to rise and cool, which leads to increased precipitation. This is known as orographic lift.
