Frost/Freeze in Willacy, Texas

Observations from the Texas AgriScience Center (corner of southwest Willacy and Hidalgo County) and a mesonet site on the Yturria Ranch near the Willacy/Kenedy line indicated nearly 10 hours of freezing (32F or lower) temperatures in inland Willacy, with a hard freeze (27F or lower) between 11 PM and 8 AM as radiational cooling maximized. Minimum temperatures were between 23 and 25F.

An Arctic cold front ushered in the coldest air mass of the season to Deep South Texas and the Rio Grande Valley with widespread cold temperatures between January 25-27, 2026. Cold temperatures (wind chill) below 30F arrived during the late evening of the 24th across the ranchlands and spread to the lower Rio Grande Valley before daybreak on the 25th. A cold afternoon set the stage for the overnight of the 25th into the morning of the 26th, as skies cleared but fresh breezes/stronger winds near the coast prevailed. The 26th was the coldest ambient and feels-like temperature of the calendar year so far, with a freeze in all areas, and wind chill below 20F in most areas.

Clear skies and calm winds allowed rapid temperature drops during the evening of the 26th, with many inland locations recording their second hard freeze in as many nights early on the 27th. Locations closer to the coast saw winds veer to the northeast above the surface, precluding a second freeze/hard freeze.

The hard freeze caused minor damage to tender vegetation and crops in Hidalgo, Willacy, and Cameron County. Dollar values were unknown as of this writing (end of March 2026) but some estimates are included, and will likely be updated.
