You’ll definitely want to grab a heavier jacket tonight because cooler air is officially rolling in. Expect mostly clear skies with temperatures dropping into the mid-40s across most of Long Island, and that lingering breeze will make it feel even chillier heading into early Tuesday morning.

Tuesday itself is shaping up to be a beautiful fall day, plenty of sunshine, though definitely crisp, with highs holding in the 60s. The real chill comes Tuesday night into Wednesday morning. Under clear skies, overnight lows will dip into the low 40s, and standard cold spots around the Pine Barrens could see the upper 30s with a bit of patchy frost.

Wednesday keeps the great weather going with lots of sun and highs in the mid-60s. It’s a classic autumn day with a brisk start, a comfortable afternoon, and clear skies all day.

By Thursday, we start to warm back up into the lower 70s with plenty of sunshine and dry conditions. Overall, expect a brief taste of cool fall air mid-week before things warm right back up toward the weekend!
