New York, New York - The Big Apple is heating up and the sweltering temperatures won't be letting up anytime soon.

The National Weather Service on Tuesday issued a heat advisory warning for noon to 8 PM on Wednesday as historically hot weather scorches the five boroughs and beyond.

Wednesday’s forecast includes a high of 95 degrees Fahrenheit, but the NWS warns the heat index could feel like 100 degrees during its peak. A similarly high heat index is expected Thursday.

"Hot temperatures and high humidity may cause heat illnesses to occur," the NWS says in its advisory.

"With maximum heat index values ranging from the mid 90s to around 100 on Wednesday and Thursday, it is important to practice heat safety! To reduce risk during outdoor work, stay hydrated and take breaks in the shade as often as possible."

Tuesday kicked off a brutal stretch of scorching weather in the Big Apple that could account for one of the city’s longest streaks of consecutive 90-degree-plus days. Eight consecutive days with these temperatures would crack the top 10 for longest stretches in New York.

The longest in the city’s history occurred in 1953, when New York recorded 12 straight days of 90-degree-plus heat.

Every day through next Monday has a projected high temperature above 90 degrees, while the subsequent days are expected to hit the high 80s.

This weekend is poised to be especially hot, with highs of about 96 on Saturday and Sunday.

New York opened cooling centers throughout the five boroughs on Tuesday to help New Yorkers beat the heat.

"I can’t emphasize enough that, yes, it’s supposed to be hot during the summer, but it’s the consecutive 90-degree days that make it really hard for our body to handle," Fox Weather meteorologist Amy Freeze told the New York Daily News.

"If you don’t have air conditioning, you don’t have a lot of time to cool off in the evening hours, because our temperatures don’t drop as dramatically in the summer."
