Recent Central Weather Administration guidance and ensemble model runs highlight persistent easterly flow and residual moisture from a low-pressure band as key drivers, keeping cloud cover and shower chances elevated yet allowing sufficient insolation for afternoon temperatures to reach the mid-30s °C. The tight market split between 34 °C and 35 °C reflects model disagreement on the exact timing and coverage of convective clouds, which can suppress peaks by 1–2 °C if widespread or permit brief clearing that pushes readings higher. Historical September baselines around 30–32 °C and current dew points near 24–26 °C further support why traders assign low probability to extremes below 33 °C or above 36 °C. Updated CWA briefings and next model cycles tomorrow morning represent the key near-term catalysts.
