Current forecast models show significant spread for New York City's overnight low on May 20, keeping the market tightly bunched around 70–77°F while leaving room for a cooler outlier near 63°F or below. A building high-pressure ridge over the eastern U.S. favors mild southerly flow and limited radiational cooling, but an approaching mid-level trough could introduce cooler air and increased cloud cover, lowering the minimum. Sea-breeze moderation and urban heat-island effects add further variability in Central Park observations. With only a few days until resolution, the next National Weather Service model runs and any shifts in 850-hPa temperatures will be the primary catalysts moving trader consensus.
