Moderate to heavy rain showers and isolated thunderstorms may produce heavy downpours Monday Night into Tuesday morning. This may lead to ponding of water in poor drainage/urban and low lying areas where the heaviest rain occurs. An isolated flash flood is possible where any training of showers or thunderstorms occur.

The attached graphic depicts the area where the threat for heavier rain and possible ponding of water is expected with the Marginal Risk across eastern NY and western New England.
