**Trader sentiment clusters tightly around 98–101°F** as the leading outcomes because official National Weather Service guidance and ensemble model runs for Dallas on July 25 project a maximum near the upper 90s to low 100s under continued hot, mostly sunny conditions. A strong surface high-pressure ridge promotes subsidence warming and limits cloud cover, while light southerly flow maintains elevated dew points that modestly boost afternoon heat indices without triggering widespread convection. Minor differences between the 98–99°F and 100–101°F bins hinge on small forecast variations in boundary-layer mixing, wind speed, and any late-day cumulus development that could shave a degree or two off the peak. Historical July climatology supports this range, with Dallas averaging highs near 95–103°F; the market’s narrow spread reflects low uncertainty in the near-term guidance ahead of final model updates on the morning of the 25th.
