Environment Canada's forecast issued April 3 projects a high of 3°C in Toronto on April 7 under a mix of sun and cloud, following weekend rains from a Colorado low and northerly winds reinforcing a cool upper trough, well below seasonal normals of 9°C. This positions specific outcomes near 0–5°C as competitive in trader sentiment, while the 50% implied probability for 6°C or higher reflects model ensemble spread—such as potential GFS/ECMWF warm biases—and recent spring volatility, including today's anomalous 22°C high. The 25.5% odds on -4°C or below highlight risks of amplified cold if high pressure strengthens, with daily ECCC updates and new model runs expected to refine probabilities amid inherent short-range forecast uncertainty.
