Thursday’s overnight hours bring a slight chance of showers and scattered thunderstorms, with a 30 percent chance for the same for early afternoon Friday, the National Weather Service said.

Thursday’s warming trend is expected to continue, with News 12 Long Island meteorologist Rich Hoffman saying the hot, humid conditions will increase on Friday, when some parts of Long Island could reach 90 degrees.

For beachgoers, there’s a high risk for rip currents on the South Shore, particularly in Suffolk, starting in the afternoon, the service said.

Hoffman said clouds increase overnight and there’s a chance for a spot shower or storm into Friday morning.

Overnight lows are in the low 70s, about 8 degrees above normal for this time of year, he said.

Friday is partly sunny, hot and humid, Hoffman said. There could be a spot shower or storm in the afternoon. Daily highs range between the mid 80s and low 90s, he said.

“A cold front Friday evening will bring a spotty shower or storm and then dry warm weather for weekend,” Hoffman said.
