Fall is here?

When I woke up this morning, it had just rained, and there was  a foggy overcast feel to the morning.  Greg says to me “It’s a nice fall morning, don’t you think?”.  Now, how in the world can it feel like fall when the temperatures are still around 90 degrees for the high and 71 for the low, with high humidity?  I am still unsure, but it does feel like a nice fall morning.  Maybe it was the rain, or the fact that we live across the street from an elementary school.  There is a slight breeze in the air, moving around the few leaves that have turned color and are dropping from the trees.  Or just maybe it is the shadows the light is casting, as the sun seems to be be not as high in the sky, as it was a month ago.  Whatever it is, it seems fall is coming, even in 90 degree weather.  So Weird!
