A strong high-pressure ridge over the eastern Great Lakes is driving southerly flow that has pushed Toronto’s temperatures well above the mid-May climatological mean of 18–20 °C. Latest model guidance from Environment Canada and NOAA shows peak surface heating on May 17 centering between 23 °C and 27 °C, with the spread reflecting subtle differences in boundary-layer mixing and the precise arrival time of the warmest air mass. Morning soundings indicate dew points rising into the low teens, supporting greater instability and potential for a few tenths of a degree extra warming if cloud cover remains limited. Traders are therefore pricing the tightly bunched 24–26 °C outcomes highest because small forecast adjustments in wind direction or insolation could easily shift the daily maximum across those thresholds before Environment Canada’s official 5 p.m. reading.
