Recent model consensus from GFS and ECMWF runs positions Shanghai's overnight low on September 19 near 24–25°C, driving the market's heavy weighting toward those outcomes. Persistent northeasterly flow, widespread cloud cover, and light rain or drizzle limit radiational cooling under high humidity near 80–90%, keeping minimums elevated compared with September climatology. Official guidance shows little model spread on steering or intensity, with the primary uncertainty tied to exact timing of any clearing that could allow a brief dip toward 23°C. No major frontal passages or typhoon influences are expected in the next 24 hours to alter the pattern.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zspd
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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). 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.
