PORTLAND, Maine — It's the first day of fall, but it'll feel more like summer.

In fact, it'll be much warmer and more humid than the first day of summer, when the low temperature was 58 and the high was only 72 degrees.

The autumnal equinox occurred at 3:50 a.m., when the sun moved directly over the equator. From now through the vernal equinox in March, the sun will be over the Southern Hemisphere.

Thin clouds will thicken up this afternoon.  A few showers will fall, especially in the mountains later on too.
