NEW YORK (WABC) -- High humidity will be the defining weather story in the days ahead, making it feel more like Florida than the Northeast. While temperatures are expected to stay below 90 degrees throughout the seven-day forecast, a stretch of middle and upper 80s combined with tropical moisture will make conditions feel considerably warmer.

Sunday will be mainly cloudy and humid, with much of the day staying dry before a possible late-day shower or thunderstorm develops west of the city. Highs will reach about 82 degrees.

The greater concern arrives Sunday night and especially during the early hours of Monday, when showers and thunderstorms are expected to become more widespread.

We are closely watching the potential for repeated rounds of rain over the same locations, a phenomenon known as training. If those heavier downpours target highly urbanized areas, localized flooding could develop, potentially affecting the Monday morning commute and continuing into the afternoon, prompting Monday to be designated an AccuWeather Alert Day.

Monday will be very humid with highs near 81 degrees. While the day will not be a complete washout, rainfall could be intense at times.

Tuesday appears to be the most favorable day of the week, featuring a mix of humidity and sunshine with only a slight chance of a spotty storm and a high near 82 degrees. More showers are expected Wednesday with highs around 83 degrees.

From Thursday through Saturday, weather conditions become more typical of summer, with a chance for an afternoon shower or thunderstorm each day and temperatures climbing into the middle and upper 80s.
