WHITE CHRISTMAS!!! For most of the nation, this isn’t much of a snowfall. But for the Rio Grande Valley, it’s history on the hoof. This 1 inch blanket—up to 3 inches in some places—came on Christmas morning, 2004, and was the first measurable snowfall in the Valley in 109 years. There reportedly was no living human in South Texas who could remember snow on the ground in the Valley. It was such a stunning event for the locals that there have been three, or is it four, collections of photos published. But don’t blink—by late afternoon it was mostly gone.
