A stalled frontal boundary and associated moisture surge over the eastern and central United States are driving scattered showers and thunderstorms across the mid-Atlantic and Northeast on September 21, with National Weather Service guidance showing 50-90% rain probabilities and localized heavy totals possible in the Ohio Valley and Appalachians. In South Asia, a developing low-pressure system in the Bay of Bengal is expected to deliver widespread heavy rainfall and gusty winds to parts of India, Tamil Nadu, and coastal Odisha per India Meteorological Department alerts. Model consensus highlights typical September variability, with higher precipitation likelihoods tied to these synoptic features rather than tropical systems, while drier conditions prevail elsewhere such as the western U.S. and parts of Europe. Traders should monitor updated NWS and IMD short-range forecasts, as small shifts in frontal position or moisture transport can alter resolution outcomes for specific locations.

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.
