Long Island weather: Heat advisory continues, chance of storms

After flooding and fires Tuesday, similar conditions of heat and humidity are back, forecasters said, but any storms are predicted to be less intense.

A heat advisory for hot and muggy weather is in effect again Wednesday for most of Long Island, and there is a possibility of more thunderstorms at night, forecasters said.

The skies were still "unsettled," but Wednesday night's weather was not going to be anywhere close to the intensity of Tuesday night's storms, said meteorologist John Murray of the National Weather Service in Upton. 

The chances of heavy rain, thunder and lightning have been slipping down to about 30 percent, Murray said. "The main threat is the locally heavy rain," he said.

News 12 Long Island meteorologist Bruce Avery agreed. “I don’t think we’re going to see the kind of violent storms we saw last night," he said. "But the same hot and humid conditions are still around."

The East End escaped any damage from Tuesday night's storms, Avery said. He added that the Twin Forks area was the only part of the Island not under a heat advisory Wednesday.

Tuesday night's storms had flooded streets and caused fires throughout Nassau County. 

“This was a real mess," Avery said.

Temperatures will hit a high in the upper 80s Wednesday, but it will be several degrees cooler on the East End, the National Weather Service said.

There is a chance of showers again Thursday morning, but after 4 p.m., the day should be partly sunny, with temperatures hitting a high in the upper 80s, the weather service said.

Friday should be sunny all day with temperatures again rising to the upper 80s, the weather service said, but showers and thunderstorms have a chance of returning both Saturday and Sunday.
