The sky is more of a dull whitish haze and never the deep blue it used to be. The cloud deck is lower for cumulus and higher for cirrus, according to some, and it does seem that way to me. This is supposedly due to changing electric properties, i.e. the magnetosphere, and other factors. And I've noticed "chembows" more often; their colors remind me of what you see in a puddle of spilled motor oil.

The sun is much brighter and whiter. It also seems to throw shadows in odd directions for the seasons, and I've been in the same house for almost 20 years. And it seems to get more "halos" lately. In summer it feels much hotter on my skin, and in winter it puts a lot of heat through the windows. The moon just seems to have some odd earth-shadow lines when not full.
