Key takeaway There will be highs this afternoon reaching the low 100s for areas along and west of I-69E.
Why this matters in The McAllen
The heat wave that shattered daily records in McAllen, Harlingen, and Brownsville on Wednesday will persist, with temperatures expected to reach the low 100s in areas along and west of I-69E on Thursday. While the potential arrival of Bertha may bring some rain, it's unlikely to provide significant relief from the heat. For residents of the Rio Grande Valley, this means continued strain on the power grid and increased risk of heat-related illnesses. The McAllen-Edinburg-Mission metro area, already accustomed to hot summers, will need to take extra precautions to stay safe, particularly for vulnerable populations such as the elderly and young children. As the heat wave continues, local authorities and residents will be watching closely to see if the promised rain materializes, and if it will be enough to mitigate the effects of the prolonged hot spell.
