The smoke is likely to be an intermittent issue until this fire is well under control, which is not going to be the case in the next week. It's currently only 7% contained and burning in steep and deep terrain making it more challenging to fight than the average wildfire. Whether or not smoke is a problem for any particular area downwind on any given day will be dependent on the wind direction at the time, and anyone who pays any attention to weather knows that wind direction can shift significantly within a few hours. If I had plans for the Sierra backcountry coming up, I'd be following the weather forecast daily.
