Tonight: Long Island stays pleasant and dry through the evening, with temperatures milder than usual for late March. Clouds will increase and showers will start moving in later tonight, first across Nassau County, spreading eastward across the island overnight. Most places will see light rain, and it should start winding down around or just before sunrise on Friday.

Friday: A few leftover showers are possible early in the morning, especially out east, but most of the day will turn drier. Temperatures will be noticeably cooler than today, settling into the low 50s, which is closer to what we normally expect this time of year.

Friday Night into Saturday: Cold air rushes in Friday night, setting the stage for a much colder start to the weekend. There’s a small chance of a brief mix of light rain or even a few wet snowflakes, but nothing significant is expected. Saturday will feel more like winter than spring—breezy and chilly, with temperatures only reaching the low to mid-40s and wind chills in the 20s early in the day.

Sunday into Early Next Week: After a freezing cold Saturday night, conditions slowly improve. Sunday turns milder, and temperatures continue to recover into early next week. By Tuesday and Wednesday, there’s a chance for even warmer weather to return, especially away from the immediate coast, depending on how the next weather system sets up.
