Official weather observations from Austin stations, including Camp Mabry, recorded a daily maximum of 96–97°F on September 17 amid a broader late-summer heat pattern that has produced multiple days above 95°F. National Weather Service data and numerical model runs showed persistent southerly flow, limited cloud cover, and above-normal 500-hPa heights sustaining surface temperatures well above the 1991–2020 average high of ~91°F. This outcome aligns with the month’s trajectory toward record warmth, where observed values clustered tightly in the upper 90s. Minor station-to-station variance or post-processing adjustments could theoretically shift the official reading, yet the convergence of multiple independent reports leaves little room for reclassification outside the 96–97°F bin.
