A passing wave of low pressure and trailing cold front are driving elevated rain chances across the Northeast US on September 13, 2026, with widespread showers and embedded thunderstorms expected overnight into the morning hours before gradual clearing. National Weather Service forecasts indicate a high probability of measurable precipitation in the New York and Albany regions, supported by southerly moisture transport and dew points rising into the upper 60s, though totals may vary with localized heavy bands. In contrast, Florida faces scattered afternoon storms at 40-50% odds, while California and parts of the Southeast remain mostly dry under high pressure. Traders should watch real-time NWS radar, satellite observations, and updated model runs for confirmation of precipitation thresholds in specific cities, as steering patterns and timing can shift outcomes quickly on the day of resolution.

Measurable precipitation means 0.01 inches or more as reported by the PRECIPITATION (IN) figure in the NWS Daily Climate Report (CLI) for the city's station.
A report of trace ("T") does not qualify.
The PRECIPITATION (IN) figure measures total liquid-equivalent precipitation and does not distinguish between precipitation types.
The observation period is the NWS climate day for KNYC: midnight to midnight local standard time. The final CLI report for a climate day is issued the following morning.
This market will resolve according to the NWS Daily Climate Report as published by 2:00 PM ET on the day following the observation date. If multiple versions of the report are issued, the last version published before that time governs. If no figure has been published by that time, this market will resolve to "No".
The resolution source for this market is the NWS Daily Climate Report (CLI) for KNYC, published at https://forecast.weather.gov/product.php?site=NWS&product=CLI&issuedby=NYC.
