Recent clearing after early-October rains and cooling has established sunny to partly cloudy conditions under northeasterly flow and building high pressure, supporting afternoon highs near 31–33 °C for October 9. Light winds of 5–8 mph limit mixing while urban heat-island effects and low humidity (around 50–60 %) enhance daytime warming; model consensus shows modest spread from subtle differences in cloud cover and boundary-layer depth. These factors explain the tight clustering around 31–33 °C in trader pricing, with upside to 34 °C possible if subsidence strengthens further and downside to 30 °C if residual moisture increases. Updated NMC and ECMWF runs on October 8 will refine the exact maximum.
