A cold front interacting with anomalously high precipitable water values (1.75–2.0+ inches) is driving scattered showers and thunderstorms across the Ohio Valley, central Appalachians, Mid-Atlantic, and parts of the South-Central Plains and Mid-Mississippi Valley on September 10. National Weather Service and Weather Prediction Center guidance highlights a slight risk of excessive rainfall in these corridors, with 2–3 inches per hour rates possible in training storms amid 1,000–2,000 J/kg MUCAPE. Highest probabilities today center on northern Indiana, central Ohio, western Pennsylvania, and portions of the Gulf Coast and Southeast, where National Weather Service forecasts show 50–80% chances of measurable precipitation. Model consensus favors continued activity through the evening before the boundary lifts, with lighter or isolated chances farther west and northeast.

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.
