Cool for now, then record-challenging heat (upper-90s) later today. Possible development in the Caribbean, those along Gulf of Mexico need to watch. Good morning! Yesterday, San Antonio tied a record with a high temperature of 97°. While we were among the hottest places in the country, we weren’t the hottest. That distinction belonged to Phoenix, which hit 113°! Today, we are forecasting 97°. Should we hit that mark, that would surpass the record high of 96° set in 1996. Skies will be sunny and humidity will remain low. Temperatures will come down slightly by the end of the work week, as humidity levels inch up and more clouds develop.
