9/22/11 It's the End of the Summer...

Summer ends tomorrow morning at 5:05 AM, when the sun's direct rays will be on the equator.

Sunrise in Boston will be 6:31 AM and sunset at 6:42 PM. 

During the equinox, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. Furthermore, the sun takes longer to rise and set farther from the equator because it does not set straight down - it moves in a horizontal direction.
Moreover, there is an atmospheric refraction that causes the sun's disk to appear higher in the sky than it would if earth had no atmosphere.

As for the weather, there will be a hint of summer remaining with high humidity and temperatures in the 70's to near 80.

The weather pattern will be stuck until next Thursday with some slight variations each and every day.

An area of Low pressure will stall out over Ohio for the next 7 days as the jet stream to the north will "leave the low behind" or be cut off from the main flow.  This combined with the High off of the East coast will allow moisture to converge from the Gulf of Mexico ahead of the low.   For New England, the flow will split at times allowing for a break in the rain as the dominating high and low battle. Also, pockets of drier air will work in from time to time.
