Flooding Threat in Parts of Texas and New Mexico; Heat in the Western U.S.

Heavy to excessive rainfall across parts of central Texas into southern New Mexico may bring areas of flooding into this evening. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Hot temperatures are forecast for the far southwest U.S., parts of California, and the interior northwest U.S. this week. Read More >

The Autumnal Equinox occurred early this morning (Wednesday, September 23, 2015) at 3:21 AM CDT. This was the start of astronomical fall in the Northern Hemisphere, as the sun's rays were directly overhead on the equator. Interesting tidbit, the word "equinox" is derived from two Latin words - aequus (meaning "equal") and nox (meaning "night").

On the two equinoxes (fall and spring), the length of day and night are nearly equal. The nearly equal hours of day and night are due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon when the actual position of the sun is below the horizon. The days will continue to slowly get shorter over the next couple of months, as the direct rays of the sun move slowly southward.
