Fall Arrives Late Wednesday Night

But it will still feel rather summer-like for awhile. Through at least next Tuesday, highs will be in the mid-80s to low 90s with lots of sunshine and humidity in the mix.

Here are some sky highlights of this 2010 September equinox. If your sky is clear, you can glimpse an almost full Harvest moon in the east after sunset on this equinox evening. The crest of the moon's full phase will come only six hours after the exact moment of the 2010 September equinox (4:17 a.m. Thursday, Texas time).

This is the northern hemisphere's legendary Harvest Moon and the southern hemisphere's first full moon of spring. What's more, there is a blazing star like light near tonight's moon. It is the solar system's largest planet Jupiter, which just yesterday reached its opposition – when Earth flew between Jupiter and the sun.

The full moon will not fall on the September equinox again until the year 2029, and Jupiter's next comparably good appearance on the September equinox will not happen for another 12 years.
