KEY POINTS
- A weather station at Falcon Dam, Texas, recorded a high of 106°F on Thursday afternoon, nearly 30 degrees above the historical February average of 77°F.
- If officially confirmed by NOAA, this would be the highest temperature ever recorded in the U.S. during meteorological winter (December, January, and February).
- The previous record of 104°F stood for over a century, originally measured in Rio Grande City, Texas, back in 1902.
A historic heat spike has gripped South Texas, pushing temperatures into triple digits during a time when much of the country is still grappling with winter conditions. The most significant reading came from a NOAA Cooperative Observer Program (COOP) station at Falcon Dam, located at the Falcon Reservoir along the Mexico border. The 106-degree observation is being hailed by meteorologists as a potentially unprecedented event for the U.S. mainland during the winter season.
While South Texas is known for its warmth, 106 degrees is considered extreme even for the peak of summer. Other nearby stations also reported exceptional heat, including an automated station in La Puerta that hit 104°F and Zapata, which reached 103°F. Across the border in Mexico, similar extremes were observed, with the city of Colombia also recording 106°F. These figures suggest a widespread and intense heat dome centered over the Rio Grande Valley.
The verification process for such a record is rigorous and can take several months or even years. NOAA’s National Centers for Environmental Information must confirm the equipment’s accuracy and the validity of the reading before it is officially entered into the national record books. If it passes, it will unseat the long-standing record of 104°F set in February 1902.
Forecasters note that while temperatures have “throttled back” slightly since the peak on Thursday, the region remains unseasonably hot. Highs are expected to stay in the 90s—roughly 15 to 20 degrees above historical averages—well into the start of the week. Meteorologists are also watching for another potential heat spike by the middle of next week as a new weather front approaches the area.
This extreme event isn’t isolated to Texas; record-challenging warmth has also been felt further west, including parts of Southern California. The intensity of this heatwave underscores an increasingly volatile climate where seasonal norms are being frequently challenged by record-breaking anomalies.
