As a significant winter storm approaches the Houston area, snow, sleet and ice are all becoming certainties as the temperatures decrease and conditions are forecasted to be more frosty than expected.

Temperatures are expected to dip below freezing on Sunday night, according to the National Weather Service. As of Friday, Houston's forecast also called for a likelihood of snow on Monday night and Tuesday morning.

The potential for sleet or ice during next week’s freeze is becoming more certain as the weather forecasts for the coming days become clearer.
