Trader consensus clusters tightly around 50–53°F because National Weather Service and ensemble model guidance project an overnight low in the low-to-mid 50s under partly cloudy skies, light northerly winds, and weak onshore flow typical of late-September patterns. Radiational cooling under brief clear intervals could push readings toward 50–51°F, while slightly higher dew points or increased cloud cover would favor 52–53°F. Recent high-pressure building has maintained near-seasonal temperatures with no strong frontal systems yet; the next model cycles and NWS updates before sunset on the 20th will refine the exact minimum and may shift positioning among these adjacent bins.
