A break from the hot and humid weather is expected Wednesday but sunny skies will remain following overnight showers in some areas.

Tuesday was to mark the end of the recent stretch of hot and humid days that prompted the National Weather Service to issue a heat advisory. Highs within the New York City metro area reached the middle to upper 90s, with lower to middle 90s outside the metro area, the weather service said.

Tuesday’s high in Islip was 95.

The weather service had advised widespread maximum heat index values in the 95 to 104 range, should be expected.

In Islip the heat index was 101, 102 in Shirley and 104 in Farmingdale.

The heat index is a measure of how hot it really feels when relative humidity is factored in with air temperature. 

Overnight Tuesday a few showers are expected further east, with temperatures falling into the lower 70s. For Wednesday temperatures should be dry and cooler than in recent days with highs in the upper 80s, which is still above normal for Long Island, but the humidity will be down, Meteorologist Faye Marrone said.

Normal temperatures for Islip at this time of the year is 82.

The Thursday to Sunday period is expected to be bright and clear with highs in the mid 80s.

Rain might return Sunday night — the odds are 40%, and they rise to 50% on Monday, the weather service said.
