Trader consensus on Polymarket reflects National Weather Service guidance and ensemble model outputs projecting Miami's May 15 overnight low in the mid-70s°F, with 74-75°F (30%) edging 76-77°F (23.5%) due to subtle differences in forecasted cloud cover and wind regimes. Persistent southerly flow transports moist tropical air with dewpoints near 74°F, capping radiative cooling, while diurnal sea-breeze thunderstorms may leave lingering mid-level clouds overnight—potentially trapping heat for higher lows—or dissipate for fuller clears yielding 74°F. Historical climatology at Miami International Airport shows average May 15 lows around 75°F, amplifying uncertainty amid typical short-range forecast spreads. Watch 12Z GFS/ECMWF runs and evening NWS updates for refinements ahead of resolution.
