Environment Canada’s latest forecast, issued May 14 for Toronto Pearson International Airport, projects a sunny high of 23°C on May 17 amid a warming trend from early-week cool, cloudy conditions with highs near 10–19°C. Trader consensus reflects this with 22% implied probability on exactly 23°C, but prices 29% odds for 27°C or higher due to ensemble spread in GFS and ECMWF models showing potential upper-ridge strengthening and persistent southerly flow overriding typical Lake Ontario moderation. Key differentiators include cloud cover evolution from possible Saturday showers, wind direction shifts, and urban heat effects versus airport readings; new 00z/12z model runs today could sharpen probabilities as resolution approaches in 48 hours. Historical May 17 highs average 20°C, underscoring spring variability.
