Monsoonal moisture and atmospheric instability will bring chances for afternoon and evening thunderstorms east of the Cascades to start the week ahead. These chances are very slight (5-10%) on Monday, increasing to 20-25% by Wednesday. With increased moisture on Wednesday, chances for locally heavy rainfall and severe activity are present, but not generally expected. A stray storm or two may develop west of the Cascades on Tuesday and Wednesday.

With wildfire smoke accumulating in parts of northern California and southern Oregon, knowing the steps that can be taken to limit smoke in your home can reduce its impact on your day-to-day life. Fixing seals on windows, stocking up on air filters, maintaining your air conditioner, and using HEPA filters are all ways to create a "defensible space" of higher air quality in your home. And while masks can help during time outdoors, bring aware of areas with cleaner air (malls, libraries, civic centers) is another way to stay safe during times of poor air quality.
