| Area Forecast Discussion National Weather Service New York NY 913am EST Thu Nov 20 2025 Synopsis High pressure remains in control through Friday. A weak cold front and wave of low pressure then impact the area Friday night into early Saturday. High pressure then returns for much of the weekend and remains in place through early Tuesday. Another frontal system looks to impact the area late Tuesday into Wednesday. Near Term - Through Tonight High pressure will be over the region, providing us with dry and mainly clear conditions outside of some cirrus this morning and some cloud cover rolling back in late tonight. High temperatures around 5 degree below normal. Tonight's low temperatures in some areas may occur before the typical near-sunrise timeframe due to clouds shifting in. Blended in MAV/MET MOS with NBM to help capture radiational cooling beforehand. Short Term - Friday Through Saturday Night High pressure hangs on long enough to keep us dry during the daytime on Friday. More clouds around versus today, but at least it will be milder with highs mostly in the lower and middle 50s. Uncertainty then increases Friday night into Saturday morning regarding rain chances. In general, American models are farther north with a wave of low pressure and more favorable positioning of an upper jet streak coupling. The northern fringe of the rain shield is therefore farther north, bringing rainfall across the entire forecast area. NBM Probability of Precipitation seem to fairly represent the drier and wetter solutions among the various models and ensembles. Above 50% rain chances have therefore been kept for the southernmost zones. No hydrologic impacts expected in any case. Rain would be most likely late Friday night/early Saturday morning. High pressure then builds back in for rest of Saturday with clearing and dry conditions. Highs for Saturday near normal in the upper 40s to lower 50s. Long Term - Sunday Through Wednesday NBM was followed with no significant changes. Key Points: * Rain appears to be likely Tuesday night with rain still possible into Wednesday. Hydrologic impacts, if any, would appear to be limited at this point, but too early have high confidence. * Dry weather otherwise during the long term period with close to normal temperatures. Marine Sub-advisory conditions will prevail through Sunday with high pressure dominating most of the period. There however could be a few gusts near 25kt on the ocean waters Saturday night and evening with a wave of low pressure briefly tightening the pressure gradient. Next chance of advisory thresholds otherwise would be on Monday. Hydrology No hydrologic impacts are anticipated through the forecast period.
