National Weather Service Storm Prediction Center outlooks on September 14 placed a slight risk of severe thunderstorms, including tornadoes, across eastern Nebraska into western and central Iowa, with a Tornado Watch covering that corridor through midnight. Favorable parameters included moderate instability, strong low-level shear from a 40-50 kt jet, and supercell potential, though lingering inhibition created some uncertainty about surface-based storms. Omaha, Lincoln, Des Moines, and Sioux City sat within the highest-probability tornado contours. An isolated EF-0 tornado occurred earlier in Virginia, outside the main risk area. Updated model runs and real-time radar data from SPC and local NWS offices determined final city-level impacts for market resolution.

This market will resolve to "Yes" if Chicago, IL falls within a tornado probability area rated ≥2% in the NOAA Storm Prediction Center Day 1 Convective Outlook on September 14, 2026. Otherwise, this market will resolve to "No".
The SPC Day 1 Convective Outlook assigns tornado probability percentages (2%, 5%, 10%, etc.) to geographic areas across the US. If the city's coordinates fall inside any area rated 2% or higher, that city resolves "Yes". If a city is outside all tornado probability areas, or only within areas rated below 2%, that city resolves "No".
The SPC outlook is published as machine-readable geographic data (GeoJSON) at spc.noaa.gov. Each city's coordinates and the polygon boundaries are publicly verifiable. Borderline cases can be independently confirmed using the polygon data (excluding the hatched SIGN overlay, which is not a probability rating) and the city's listed coordinates. The point-in-polygon test is performed on unprojected WGS84 (EPSG:4326) coordinates, which is the native coordinate system of the SPC GeoJSON data.
Resolution is based on the scheduled 01:00 UTC Day 1 Convective Outlook update issued on the following UTC calendar day. The SPC Day 1 outlook covers a 24-hour period from 12:00 UTC to 12:00 UTC the following day. Subsequent revisions published after that scheduled update will not be considered. If the SPC Day 1 Convective Outlook has not been published by the time the market closes, this market will resolve to "No".
The resolution source for this market is the NOAA Storm Prediction Center at spc.noaa.gov.

This market uses coordinates 34.7465, -92.2896 for Little Rock, AR.National Weather Service Storm Prediction Center outlooks on September 14 placed a slight risk of severe thunderstorms, including tornadoes, across eastern Nebraska into western and central Iowa, with a Tornado Watch covering that corridor through midnight. Favorable parameters included moderate instability, strong low-level shear from a 40-50 kt jet, and supercell potential, though lingering inhibition created some uncertainty about surface-based storms. Omaha, Lincoln, Des Moines, and Sioux City sat within the highest-probability tornado contours. An isolated EF-0 tornado occurred earlier in Virginia, outside the main risk area. Updated model runs and real-time radar data from SPC and local NWS offices determined final city-level impacts for market resolution.

If a city is outside all tornado probability areas, or only within areas rated below 2%, that city resolves "No".
The SPC outlook is published as machine-readable geographic data (GeoJSON) at spc.noaa.gov. Each city's coordinates and the polygon boundaries are publicly verifiable. Borderline cases can be independently confirmed using the polygon data (excluding the hatched SIGN overlay, which is not a probability rating) and the city's listed coordinates. The point-in-polygon test is performed on unprojected WGS84 (EPSG:4326) coordinates, which is the native coordinate system of the SPC GeoJSON data.
Resolution is based on the scheduled 01:00 UTC Day 1 Convective Outlook update issued on the following UTC calendar day. The SPC Day 1 outlook covers a 24-hour period from 12:00 UTC to 12:00 UTC the following day. Subsequent revisions published after that scheduled update will not be considered. If the SPC Day 1 Convective Outlook has not been published by the time the market closes, this market will resolve to "No".

This market uses coordinates 34.7465, -92.2896 for Little Rock, AR.National Weather Service Storm Prediction Center outlooks on September 14 placed a slight risk of severe thunderstorms, including tornadoes, across eastern Nebraska into western and central Iowa, with a Tornado Watch covering that corridor through midnight. Favorable parameters included moderate instability, strong low-level shear from a 40-50 kt jet, and supercell potential, though lingering inhibition created some uncertainty about surface-based storms. Omaha, Lincoln, Des Moines, and Sioux City sat within the highest-probability tornado contours. An isolated EF-0 tornado occurred earlier in Virginia, outside the main risk area. Updated model runs and real-time radar data from SPC and local NWS offices determined final city-level impacts for market resolution.
