Long Island weather: 'Oppressive' heat and humidity with temps in upper 80s

It will be sunny and hot Monday on Long Island, followed by a heat advisory for Tuesday and Wednesday.

The temperature was expected to hit a high in the upper 80s Monday and then move into the low 90s late Tuesday morning and into Wednesday evening, the National Weather Service said.

“We will have uncomfortable to oppressive levels of heat and humidity today, and also for Tuesday and Wednesday,” News 12 Long Island meteorologist Rich Hoffman said.

During a heat advisory, the heat and humidity can pose a health risk to the elderly and other at-risk people.

A heat advisory is issued when the combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees for any length of time.

The temperature was expected to drop just below 90 degrees on Thursday, when there is a chance of showers and thunderstorms after noon, the weather service said. However, the heat advisory may need to be extended into Thursday for portions of western Long Island, the weather service said.

Friday should bring more relief as the temperatures reach a high of 80 degrees or less, forecasters said.
