The taller the smoke column gets, it can turn into pyrocumulus which we’ve seen a lot of that past couple of weeks now, but if it really gets towering into a pyrocumulonimbus, reaching over an amazing 30,000 feet, it could then create its own lightning. Of course if it’s lowering or in the midst of a column collapse, all that moisture, particulate & ash can come crashing back down with amazing force & weight behind it, much like a thunderstorm you can have tremendous downdrafts with winds blowing back outward in excess of 60mph. Not a good situation at all, and way too hot to create any rain. With any luck you’ll have just enough wind on a fire of this magnitude to keep blowing the smoke off to the northeast and not allow it to build too tall.
Here’s a great example of the Station Fire going pyrocumulus & collapsing many times over.

Beware the smoke is dropping lower and lower not a good thing this can create a thunder head and can preheat and large area at one time.
