Recent National Weather Service and model guidance point to a minimum temperature in the upper 60s to low 70s for New York City on August 28, driven by post-frontal clearing and west-to-northwest flow that reduces cloud cover and allows greater overnight radiative cooling after Thursday’s humid southerly regime and thunderstorm activity. Dew points near 60–65 °F and light winds will modulate how far temperatures fall, with the precise low hinging on the timing of any residual moisture and the strength of downslope warming versus clear-sky heat loss. Market-implied odds clustered around 68–73 °F reflect this narrow uncertainty band ahead of the final evening observations, consistent with typical late-August variability when synoptic steering patterns shift rapidly.
