On September 16, 2026, scattered showers and thunderstorms driven by a slow-moving cold front produced measurable rainfall across parts of the U.S. Midwest and South Florida, with totals of 0.1–2 inches common in Indiana and Minnesota per National Weather Service observations, while northern Vietnam and Hanoi saw heavy to very heavy rain exceeding 60–120 mm locally from persistent moisture and instability. Model consensus from NOAA highlighted frontal lifting and high dew points sustaining convection, with limited disagreement on placement but some variance in intensity. These patterns aligned with seasonal late-summer dynamics, where stalled boundaries often concentrate precipitation; traders monitoring real-time radar and gauge data from authoritative agencies would note that resolution hinges on verified daily totals at specific sites rather than forecasts. Upcoming post-event verification reports from the National Centers for Environmental Information could refine final outcomes.

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.
