**Current National Weather Service and model guidance point to a highest temperature in Dallas on June 15 in the low-to-mid 80s°F, driven by a transitional synoptic pattern featuring modest southerly flow, increasing cloud cover, and limited daytime heating under partly to mostly cloudy skies.** Ensemble forecasts show surface highs clustering near 81–84°F as weak shortwave energy and higher dew points moderate insolation compared with recent clear, hotter days. Small differences in boundary-layer mixing, timing of any scattered showers, and exact steering of the subtropical ridge create the narrow spread between the 80–81°F and 82–83°F bins that together hold over 55% market-implied probability. Later model runs or afternoon observations could still shift the peak by 1–2°F depending on convective initiation and wind shifts.
