Forecast models from the National Weather Service and major ensembles converge on a high near 90°F for New York City on August 7, driven by southwesterly flow under building high pressure with dew points in the mid-60s supporting peak readings in the upper 80s to low 90s before any afternoon convection develops. Thunderstorm timing remains the key uncertainty, as early or widespread storms could cap temperatures in the 88-89°F range while delayed activity allows readings to reach 92-93°F. The above-average signal aligns with the Climate Prediction Center’s seasonal outlook favoring warmer conditions for the Northeast, consistent with historical August patterns where Central Park highs average 83°F but can exceed 90°F during similar setups. Updated model runs tomorrow morning will refine resolution criteria tied to official observations at LaGuardia or Central Park.
