Factors Influencing Mill Creek Weather

Several geographical and atmospheric elements contribute to Mill Creek's specific weather profile. Understanding these can help anticipate conditions more effectively. — 1965 Lincoln Continental: The Definitive Buyer's Guide

The Puget Sound Convergence Zone

The Puget Sound Convergence Zone (PSCZ) is a semi-permanent feature that significantly impacts weather in the region, including Mill Creek. This zone forms when air masses moving from the north and south collide, creating a band of enhanced precipitation. When the PSCZ is active, Mill Creek can experience prolonged periods of rain, even when surrounding areas might be drier. The National Weather Service often issues advisories related to the PSCZ, which are worth monitoring.

Orographic Lift and Rain Shadows

The Olympic Mountains to the west and the Cascade Mountains to the east play a role in Mill Creek's precipitation patterns. The Olympic Mountains create a rain shadow effect, contributing to the drier summers in the Puget Sound region. Conversely, the western slopes of the Cascades receive significant rainfall. While Mill Creek is somewhat shielded, the general atmospheric flow influenced by these ranges still plays a part.
