Wednesday may be continuing the warm and muggy summerlike conditions, but that trend is set to start shifting on Thursday, forecasters say.

With the chance for some patchy fog in the morning over the East End, Thursday is starting a tilt toward more seasonable temperatures, but is still to see an above-average high in the mid to upper 70s, the National Weather Service said.

By around early afternoon Thursday, Long Islanders should begin feeling the effects of a new air mass and wind direction, resulting in “a noticeable drop in humidity” and “refreshingly dry air,” said Tim Morrin, weather service meteorologist in Upton.

The day is to be mostly sunny, windy and less humid, said News 12 Long Island meteorologist Rich Hoffman.

Friday, with sunny skies, brings highs of around 70 degrees, which is normal for this time of year.

With a continuing nod to Tropical Storm Maria, passing well to the south and east of Long Island Wednesday into Thursday, “we will see rough seas, rip currents and high surf” for the coming days, Hoffman said.

Indeed, there is a rip current advisory in effect through Thursday afternoon for ocean-facing beaches, and a high surf advisory is in effect for those areas through 6 p.m. Thursday.
