Will the highest temperature in New York City be between 52-53°F on April 9?

“NWS and AccuWeather forecast a high of 54°F for April 9, and with typical short-range forecast RMSE of ~3°F, the 52-53°F bin is well within one standard error of the forecast — placing it at roughly 20-30% probability given the error distribution.. Cool northerly flow following a cold front on April 6-7 creates conditions where the actual high could undershoot the forecast if cloud cover persists longer or winds are stronger than modeled, pushing the high down 1-2°F from the 54°F forecast into the 52-53°F range..”

“The forecast consensus of 54°F from both NWS and AccuWeather points to the 54-55°F bin as the modal outcome, not 52-53°F. The bull's argument that RMSE of ~3°F makes 52-53°F 'well within one standard error' is misleading — a symmetric ±3°F RMSE means probability mass is spread across many bins (50-51, 52-53, 54-55, 56-57, 58-59), so even granting the error distribution, the 52-53°F bin captures only roughly 15-20% of the probability, not 20-30% as claimed.. The bull's claim about LaGuardia running 1-2°F cooler than Central Park due to marine influence is directionally plausible but cuts both ways — LaGuardia can also run warmer on sunny days due to urban heat and tarmac effects. The net microclimate adjustment is not reliably negative, and the bull presents no systematic data showing LaGuardia consistently underperforms Central Park forecasts by 1-2°F in northerly flow regimes..”
