Wintry precipitation is expected for portions of the Hill Country and the southern Edwards Plateau Wednesday afternoon through early Thursday morning.

Area of Concern:

Hill Country and the southern Edwards Plateau

Threats & Impacts:

Rain/Snow Mix: A mix of rain and snow is likely Wednesday afternoon into Thursday morning across the Hill Country and southern Edwards Plateau, primarily north and west of a Comstock to Comfort to Georgetown line.

Snow: A brief period of all snow is possible early Thursday morning for far northern Val Verde, Edwards, and Real Counties and western Kerr, Gillespie and Llano Counties, where vertical temperature profiles will be most favorable for snow.

Snow Impacts: Little to no impacts are expected. Given the warm soil temperatures from the previous period of well above normal temperatures and the fact that surface temperatures should likely remain above freezing, it is unlikely that there will be any snow accumulations. Any snow should melt upon contact with the ground. However, if temperatures begin trending colder, it is possible that some very slight accumulations may be possible across the aforementioned areas where all snow is most likely, especially for northern Edwards and western Kerr Counties. The San Antonio and Austin metro areas are expected to receive all rain. If temperatures begin trending colder, it is possible that the rain/snow mix line could make its way closer to the Interstate 35 corridor.

Timing and Overview:

A strong cold front passed through the region Tuesday morning, ushering in a cold, arctic air mass. An upper level disturbance moving across Texas tomorrow will bring widespread rain showers to the area. As temperatures drop further late Wednesday afternoon into Thursday morning, this should support snowflakes mixed in with the rain, as well as the possibility of some locations to receive a brief period of all snow early Thursday morning.


Probability of Rain/Snow Mix Occuring: Moderate

Probability of All Snow Occurring: Low

Timing: Moderate to High
