Recent numerical weather prediction runs from Environment and Climate Change Canada and the Global Forecast System indicate a warm-air advection event ahead of a slow-moving frontal boundary, supporting maximum temperatures in Toronto near 28–30 °C on May 18. Ensemble members diverge modestly on cloud cover and boundary-layer mixing, producing a narrow spread that keeps the 28 °C, 29 °C, and 30 °C bins clustered within a few percentage points. Surface dew points near 15 °C and light southwesterly flow will limit evaporative cooling, while any late-day convective initiation could cap the peak below model guidance. Updated model cycles tomorrow morning and afternoon will provide the next high-resolution guidance 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 Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ.
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.
