9:45 p.m. Tuesday, Sept. 2: Moderate rain and heavy showers are moving through Western Washington currently. We are expected to dry out by Wednesday morning.

Today’s weather signaled a strong transition from Summer to Fall as the skies became more spotted with clouds and showers while winds gusting into the mid 20 mile per hour range surged throughout the afternoon. As the sun went down however, a line of strong thunderstorms formed north of Everett and raced southeast towards the Central Puget Sound and Seattle Metro Area.

The reason for this sudden change in our weather is an upper level low pressure system that has dropped down from the western coasts of Canada. The upper level low brought cold temperatures to the upper levels of the atmosphere which in turn rose the instability and brought our chances of storms.

As this upper level system clears the area we will see sunny skies and warm temperatures return, however we can expect storm systems like today’s to be on the rise as the seasons change.
