Recent National Weather Service forecasts point to a high near 97°F in Austin on June 28 under mostly sunny skies with southerly flow, aligning with the market’s tight clustering around 94–97°F outcomes. Persistent high pressure and above-average Gulf moisture are limiting stronger heating while keeping heat indices elevated, consistent with late-June climatology where daily highs average 93–95°F. Model consensus shows limited day-to-day variability this close to the event, with only modest afternoon mixing or cloud cover likely to trim the peak by a degree or two. Traders appear to weigh these stable guidance trends heavily against the small chance of slightly stronger subsidence pushing readings into the upper 90s.
