Heat Advisory, Severe Thunderstorms Possible Thursday

We are finally going to see some relief from the brutal heat soon, but Thursday is not the day. A heat advisory will be in effect for most of the island and there is the potential for severe thunderstorms later in the day.

The heat index – how hot it feels with the humidity factored in – hit 93 degrees at Long Island MacArthur Airport Wednesday and it will likely approach 100 degrees on Thursday, the National Weather Service says.

A heat advisory will be in effect from 11 a.m. until 7 p.m. for all but the East End, where the heat index will likely "only" reach the mid-90s.

Showers and thunderstorms will become increasingly likely from northwest to southeast for Thursday afternoon and evening. There is the possibility of heavy rain and gusty winds with a marginal risk of severe thunderstorms, mainly due to damaging winds, the NWS says. There is a slight risk for flash flooding.

Cooler air moves in after the storms with the high on Friday expected to be around 78 degrees. Check out the hour-by-hour forecast below.
