While snow is a rare occurrence in Houston, historical records show it has happened sporadically over the past few decades.

On February 14, 1895, the Houston area recorded a whopping 20 inches of snow. We’re not going to get there this time…not even close, so that record is safe. But as we look at some of the other snowfall totals, the one we're experiencing now has got a chance.

20 inches on Valentine's Day The mother of all snows came on Valentine's Day in 1895. Houston was hit with 20 inches of snow on Feb. 14 and 15. The snow didn't just fall in Houston. It was a massive storm that dropped snow from Tampico, Mexico, to Pensacola, Florida, and set records in New Orleans and Alabama.

Salt or the brine solution does not necessarily melt ice or snow with increased heat. It merely brings the freezing point of water to lower temperatures. At the molecular level, the salt molecules get in the way of the bonding water molecules helping it not to freeze.
