Latest National Weather Service and private-model guidance points to a July 5 high of 98–99 °F under mostly sunny skies, light southerly flow, and heat indices near 102–103 °F, aligning with the tight 29.5 % / 27.0 % market split between the 98–99 °F and 96–97 °F bins. Typical early-July Austin maxima average 96 °F; the current pattern features above-normal warmth and minimal cloud cover or precipitation that would otherwise cap temperatures. Model spread remains modest, but small shifts in boundary-layer moisture or afternoon mixing could trim or boost the peak by 1–2 °F before the daily maximum is recorded. Final NWS updates overnight and on the morning of July 5 will provide the last observational constraints ahead of market resolution.
