The Great Christmas Eve Snow Storm (2004)

The Great Christmas Eve Snow Storm (2004)

While it’s fairly common for Northern states to get a few inches of snow on Christmas Eve, it’s very rare for the South to get even an airborne flurry. Any accumulation is nearly unprecedented.

That’s why the Great Christmas Eve Snow Storm in southeast Texas and Louisiana was such a surprise. The harsh, cold weather and the snow that stuck to the ground ushered in a true white Christmas in many places. It even covered palm trees with snow. Just consider:

* Brownsville, Texas experienced 1.5 inches of snow, the first measurable snowfall at the city in 105 years (since the Great Blizzard of 1899).

* New Orleans had its first white Christmas in 50 years.

* Houston, Texas had its first white Christmas ever!

* In Corpus Christi, Texas, 5.2 inches of snow fell (more snow than had fallen in all previous years combined)

* Across all of southern Texas and southwestern Louisiana, snow fell in places where it hadn’t for anywhere from 15 to 120 years.

At the same time, the Northern U.S. and Canada received barely any snow.
Here is what happened, according to NOAA

An arctic cold front had pushed across Southeast Texas dropping temperatures below freezing, so plenty of cold air was in place Christmas Eve when the snow began. What made this event unusual was not just the cold air being in place, but the depth of the cold air that was in place over the area.

Before the heavy snow began on the night of Christmas Eve, the entire depth of the atmosphere over Southeast Texas was below freezing. Normally when winter weather events occur in Southeast Texas, the depth of the cold air is much shallower, resulting in ice (freezing rain or sleet) being a lot more common in these parts than snow.

The morning of Christmas Eve, a strong upper level low was evident on satellite across northern Mexico. Ahead of this system, some snow began across Southeast Texas, but the dry atmosphere kept the snowfall light during the day, resulting in only trace amounts or a light dusting through late afternoon. Eventually, the atmosphere moistened up by late in the day as the upper level low approached from the west.

The upper low moved across South Texas during the nighttime hours Christmas Eve, resulting in a band of heavy snowfall just north of the track of the system. The band of heaviest snowfall, about 20 miles wide, was centered from Victoria to Edna to Bay City to Lake Jackson.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1910, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
