It's already 87 degrees right now

Another scorcher is in store for Independence Day with a high near 97 forecast for Long Island.

It was 80 degrees in Islip at 7:40 a.m. and nearing 90 just before 10 a.m., according to the National Weather Service.

But as Long Islanders head to beaches, parades, barbecues and other celebrations, forecasters said the heat index would make it feel like 105.

An extreme heat warning is in effect for most of Long Island. Parts of the South Shore, including Westhampton and Montauk, are under a heat advisory, according to the weather service.

Saturday is expected to be the "last day of extreme heat," the weather service said.
