Current National Weather Service and NOAA model guidance for Dallas on July 17 points to a modest high near the mid-90s, driving the leading 29.5% implied probability on 92-93°F amid scattered clouds and possible afternoon convection that limits full solar heating. Elevated uncertainty across the distribution arises from variable steering flows, boundary-layer moisture, and urban heat-island effects that can shift the peak by several degrees. Historical July averages near 96°F provide context, yet short-term model spreads—particularly in timing of any seabreeze or thunderstorm initiation—keep outcomes from 88°F to the upper 90s viable. Updated NWS briefings and afternoon soundings tomorrow will refine these thresholds ahead of market resolution.
