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

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.

The last time Houston saw measurable snow was in Feb. 2021. This week's snowfall could have a place in the record books. The most snow ever measured in Houston was when the city saw 20 inches in 1895. HOUSTON - This week's snowfall has many thinking back about the last time that we saw snow in Houston.
