I've found there are some downsides from switching to https that may or not apply to you:
1. Yowindow stops working. It's because it's based on Flash. There doesn't seem to be any fixes. It's time for them to move on from it. So I put my Yowindow pages on http domain I already had.
2. If you use this satellite animation, the photos listed above the head have to be set to https. At least that is an easy fix:
https://stillwaterweather.com/sat.php For another easy fix embed youtube videos have to show https.
3. If you use Flash weather maps by NOAA, they may not work with https.
4. WU Rapid Fire doesn't work. I don't think Weather Display Live works either. Both are based on Flash. At least some of WU's PWS weather stickers work.
I hope switching to https was worth it.
