While the primary risk for thunderstorms is located east of the Cascades, there is a small possibility of isolated storm activity occurring west of the mountain range. The specific cause for this potential for isolated storms west of the Cascades was not detailed.
No specific temperature ranges or wind speeds were provided in the trend summary. The duration of the hazy mornings was also not specified. Information regarding the source of the wildfire smoke was not included.
