VIA bus routes were operating on a normal schedule, but officials said some delays were expected. 

A winter storm warning remains in effect until 6 p.m. Tuesday. 

Tuesday morning, afternoon

The long-anticipated sub-freezing air arrived and began to mix with precipitation overnight. Scattered showers of freezing rain and sleet have been moving through most of South Texas for much of the morning.

Expect areas of freezing rain and sleet to linger throughout the rest of the day, with the precipitation beginning to taper off by late afternoon.

Freezing rain looks like regular rain, but freezes when it comes in contact with something. Frozen rain is what creates a glaze of ice on surface objects. Sleet pellets are little grains of ice that  bouncing off surface objects.

Tuesday evening

The precipitation will begin diminishing throughout the afternoon and evening, but the potential for dangerous conditions will continue as temperatures will remain below the freezing mark on Tuesday and ice may remain on roads through Tuesday night.

Wednesday Morning

The low temperature is expected to be near 20 degrees and is not expected to rise above freezing until late morning Wednesday, which may not allow the ice to thaw in all areas.
