Trader consensus on NYC September precipitation centers on 2–4 inches total, reflecting modest early-month accumulation of roughly 0.9 inches through September 9 at Central Park alongside NOAA’s Climate Prediction Center outlook favoring above-normal precipitation across the Northeast. Short-term National Weather Service guidance shows scattered showers possible this weekend before drier conditions, while longer-range model runs indicate potential for additional frontal or tropical moisture later in the month. These factors create tight implied probabilities between the 2–3 inch and 3–4 inch bins, as remaining variability in storm tracks and intensity could easily shift totals within or above the historical September average of about 4 inches. Updated NWS forecasts and CPC model guidance through mid-month will likely refine trader positioning.
