Temperatures will climb into the mid-to-upper 90s under sunny skies Thursday as the ridge of high pressure reaches its pinnacle of strength on Thursday. A weak low pressure center will break off from the flow through southern Canada as we head into the weekend, which will cool us off into the low 90s Saturday and Sunday, and will also help kick up some gusty winds during the same period. By Monday and Tuesday, highs will drop back into the upper 80s.
I mentioned yesterday that because we are travelling slower around the sun we over-rotate a little in 24 hours. This effect delays the time that the sun sets each night, offsetting the shortening of the days. Conversely, it takes extra time off the morning, but it will be a while before we take the time off the evening (another week or so from now). As we speed up our orbit that offsetting effect evens out, and both sunrises get later and sunsets get earlier.
Now in the winter (late December/early January), the opposite happens… the sunrise stays the same while the sunsets start to get later. Give it six months and you’ll see.
A Word of Weather 
Ok, I hear what you are saying but I am missing something. Is it that the Earth is starting to tip back at this time so that the morning is sort of absorbing a shift in daylight?
This is going to bother me for a while.

It’s not that, but instead has to do with the fact that because we are travelling slower in our orbit around the sun right now, we don’t quite add that 1/365th of a full orbit every day this time of year. The earth is still spinning at the same rate though, which delays the time the sun rises and sets just a bit. The total day (sunrise to sunset) is still getting shorter.
It’s confusing, I know.
