Recent National Weather Service and private forecast models point to overnight lows in Miami on May 19 hovering near 77–79 °F, consistent with mid-May climatology where average minima reach 76 °F. High humidity and light winds are expected to limit radiational cooling, while any increase in cloud cover or a weak sea-breeze circulation could shave a degree or two lower. Conversely, clearer skies and calmer conditions would favor readings near 80 °F. This narrow band of outcomes keeps probabilities tightly clustered, with traders weighing the latest model runs and surface observations to resolve the exact threshold.
