Recent National Weather Service guidance and ensemble models point to a high-pressure ridge and mostly sunny conditions favoring a Denver high temperature in the low-to-mid 80s on September 9, keeping the tightly bunched 80–85 °F outcomes at the top of the market. Following early-September readings that reached the low 90s, northeasterly flow and dry air should limit afternoon mixing while allowing strong solar heating under clear skies. Minor differences among the leading bins hinge on exact peak timing, subtle cloud debris, or small wind-speed variations that can shift the daily maximum by a degree or two. Updated model runs and the NWS afternoon forecast discussion on September 8 will provide the next clear signal for traders.
