Latest ensemble forecasts from GFS and ECMWF models project Shanghai's highest temperature on April 15 near 19-20°C under overcast skies and light northerly winds, fueling the razor-thin trader split between 19°C (41%) and 20°C or higher (39.5%). Following April 14's observed high around 17-18°C amid light rain from a recent cold air influence, partial recovery is expected as high-pressure builds, but persistent cloud cover limits solar heating and introduces 1-2°C uncertainty in boundary layer forecasts. Official China Meteorological Administration guidance leans toward 21°C, yet global model consensus tempers expectations amid typical spring variability; new 12z runs today could refine odds before resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Shanghai Pudong International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
