South Texas weather is making headlines as a shocking freeze warning and cold front are set to impact the region, including the Rio Grande Valley. As temperatures continue to fluctuate, residents are urged to prepare for a cold weekend ahead.

South Texas weather: Freeze Warning and Temperature Fluctuations

The National Weather Service has issued a freeze warning for several areas in South Texas, including Cotula, Rivera, Victoria, and near George West and Three Rivers.

However, changes are expected as a cold front arrives early on Friday. This frontal boundary will bring cold conditions and rain, especially to cities along the coastal region, affecting the Rio Grande Valley. Isolated showers are predicted on Friday, with temperatures remaining pleasant in the upper 60s and lower 70s before the cold front causes a slight drop.

As South Texas prepares for the weekend, residents should expect colder temperatures. On Friday, temperatures will reach a high of 65 degrees in the afternoon, with increased cloud coverage. Clear and sunny skies are expected on Saturday, with a high of 62 degrees, but evening temperatures will plummet to between 38-40 degrees. Rain chances will return on Monday, making it crucial for residents to stay informed and prepared for these changing weather conditions.
