A high-impact winter storm will bring freezing rain, sleet, and snow to the southeastern half of Texas Monday evening through Tuesday afternoon. Hazardous road conditions will make travel extremely difficult through Wednesday morning in those regions, including major metropolitan zones like Austin, San Antonio, Bryan/College Station, Corpus Christi, Victoria, Houston, and Beaumont.
As surface temperatures fall below freezing Monday evening, light rain will change over to freezing rain and sleet across the Edwards Plateau, South Texas, Hill Country, Central Texas, Brazos Valley, Coastal Bend, Coastal Plains, Southeast Texas, and the Golden Triangle. There are questions about the type of winter precipitation (freezing rain or sleet) to start off. Either will deposit a thin layer of ice on exposed objects, though sleet would also tend to cause roads to deteriorate more quickly.

Snow will begin mixing in Tuesday morning, especially east of Interstate 35 into the Brazos Valley, Southeast Texas, Piney Woods of East Texas, and the Golden Triangle. Sleet, snow—or a heavy mix of both—will continue through the late morning hours Tuesday before moving east of Texas.
Specific accumulations will depend on exactly what frozen precipitation falls and for how long. If we deal with mostly sleet and snow as a mix, we can expect significant accumulations of one to three inches across the Brazos Valley, Coastal Plains, Southeast Texas, and Golden Triangle. If we switch over to mostly wet snow, a possibility for Southeast Texas (including Houston) into the Golden Triangle and Piney Woods of East Texas (including Beaumont to Jasper), we may see overall snow accumulations exceed five inches. This would result in one of the snowiest days in Southeast Texas recorded history (back to the late 1800s). We simply can’t determine this yet, since a thin layer of warm air a few thousand feet above the surface will dictate if we’re dealing with all snow—or a trifecta of winter mischief.
We will be LIVE at 9 PM CT this evening for a question/answer session and briefing on our YouTube Channel. That live video will be carried on our website and mobile app, too.
