Trader consensus favors a mild high of 6°C or higher in Toronto on March 24 at 38.5% implied probability, driven by the latest Environment Canada and ECMWF model ensembles forecasting daytime peaks of 5-8°C amid a high-pressure ridge ushering southerly flow. Supporting this, recent GFS updates show consistent warming trends following a brief cool snap, with morning soundings indicating stable boundary layers conducive to diurnal heating. Historical March 24 highs average 6°C, aligning with these projections, though low-level cloud cover introduces uncertainty—potentially capping temps at 4-5°C (38% combined odds). Traders eye afternoon model refreshes for resolution shifts before midnight UTC cutoff.
