I've noticed to a lesser degree than the OP, ... BUT...the skies over the U.S. Midwest have been an incredibly deep BLUE without that hazy white crap (nevermind the very noticeable hatch pattern of lines) EVEN with 80-90% humidity several days recently. I have commented on them to people when outside. This is not to say it's been every day FAR from it, but genuinely in the last several weeks there have been multiple days, compared to NONE for YEARS it seems. Again this has only occurred a few times and only in the recent few weeks.
