All that are unpredictable variables, vs. what we see that's heading our way from the Pacific, and coming down from Canada 98.6% of the time. The remainder is we're on tha tail-end of the Monsoonal pattern, and what we raely get back-tracking from the east is all unpredicatable.
Even El Nino and La Nina are unknowns on what may evenually happen to us in my part of the country when they kick into gear.
We don't get any Saharan dust & out last volcano erupted ~48 yrs ago.
Whatever happens in your area(s) have no bearing on us.
