Small snowflakes or sleet could fall from the cold clouds over Houston on Tuesday. By 7 a.m., there were already some reports and indications of sleet on the south side of the Houston area, near Texas City and Pearland. ABC13 Meteorologist Travis Herzog said a strong jet stream disturbance working with a limited amount of moisture could do the trick during the afternoon and evening hours of Tuesday. A weaker jet stream disturbance over south central Texas already produced a mix of snow, sleet, and rain west of Houston. Once the stronger disturbance clears out Tuesday night, the temperatures will plummet into the upper 10s and low 20s across most of Southeast Texas. That is hard freeze territory for the area's building codes, which could put pipes at risk of bursting. From ABC13
