NOAA’s updated September outlook tilts toward above-normal precipitation across the Northeast, supporting the market’s clustering around 3–5 inches given NYC’s 4.3-inch historical average. Central Park has already recorded roughly 0.7 inches through September 4 following early-month showers that delayed the U.S. Open. Short-term forecasts show mostly dry conditions after the initial wet spell, yet dynamical guidance highlights potential for additional rainfall from troughing patterns or late-month tropical moisture. With nearly three-quarters of the month remaining, traders weigh the official wetter signal against high historical variability and the low odds currently assigned to extremes below 2 or above 6 inches.

If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
The resolution source for this market will be NOAA, specifically the figure for September 2026 when the "Monthly summarized data" for "Central Park NY" is selected with the variable set to "Precipitation" at the https://www.weather.gov/wrh/climate?wfo=okx link once that figure is finalized for the whole month of September 2026.
If the relevant data is not available by December 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
The resolution source for this market measures precipitation to 2 decimal places (e.g., 1.54), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
