Official National Weather Service and NOAA forecasts for Chicago on August 30, 2026, center on a high in the mid-to-upper 80s under mostly cloudy skies, with a 30-50% chance of scattered showers or thunderstorms and southwesterly winds gusting to 25-30 mph. These conditions create tight uncertainty around peak heating: persistent cloud cover reduces incoming solar radiation and caps temperatures near 82-85°F, while any afternoon breaks or delayed precipitation could allow brief additional warming into the mid-80s. A warm, humid air mass advected from the south supports the upper end of the range, yet evaporative cooling from showers and strong mixing from breezy flow tend to suppress extremes. Historical August 30 averages near 81°F provide context, but current model consensus and early-day observations around 76°F reinforce the narrow spread between the two leading market outcomes.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=kord
This market will resolve off of the Hourly Data provided using the "Show Hourly Data" button.
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to US Units w/ kts" button until the relevant table displays °F.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Fahrenheit (eg, 21°F). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
