A Winter Weather Advisory remains in effect for the Hill Country and central Texas through 6 p.m. Tuesday.
Bexar County was not included in the advisory but has a slight chance to see the wintry mix or accumulations of sleet and ice.
According to the National Weather Service, winter precipitation was possible for a few hours along the Balcones Escarpment Tuesday morning.
Near freezing temperatures will continue over portions of the Balcones Escarpment through daybreak.

The potential icing is expected to end by 10 a.m. with the potential impacts being mainly on exposed surfaces such as bridges and overpasses.
However, morning commuters traveling north of a line from Del Rio to Concan to Helotes will need to take extra precautions in case roads become slippery, according to the NWS.
