RIO GRANDE VALLEY, TX – Residents of the Rio Grande Valley should brace themselves for a dramatic shift in weather as an Arctic cold front makes its way into the region. The unseasonably warm temperatures that have blanketed South Texas will soon be replaced by chilly winds, cloud cover, and possible rain showers.
A Sharp Drop in Temperatures
The cold front is set to arrive late Tuesday, February 18, with an expected high of 88°F in McAllen before temperatures plunge into the low 40s overnight. Brownsville, Harlingen, and other cities across the Valley will also experience the cooldown. By Wednesday, daytime highs will struggle to surpass the low 50s, and nighttime lows will dip into the upper 30s.
The sharp contrast in temperatures has prompted local meteorologists to advise residents to take precautions, especially for those unaccustomed to such cold spells in the region.

Cold Weather Precautions

- Protect Pets & Plants – Bring pets indoors and cover sensitive plants to prevent frost damage.

- Dress Warmly – Wear layers and keep warm, especially during overnight lows.
A Slow Return to Warmer Weather
Temperatures are expected to rebound by Sunday, February 23, with highs reaching the upper 60s and lower 70s. The warming trend will continue into Monday, with sunshine and highs approaching the low 80s once again.
For now, however, South Texans must prepare for a rare extended cold spell that will make this week feel more like winter than the usual warm February days the region is accustomed to.
