Long Island residents should prepare for a week of unpredictable weather as the forecast brings major temperature swings, gusty winds, and even the chance of thunderstorms. If you’ve been enjoying the warmer days, don’t get too comfortable—a sudden cooldown is on the way. From sunny and warm afternoons to rainy, chilly evenings, the next several days will be anything but predictable. Here’s what’s in store for Long Island this week and how you can prepare.

Thursday: A Quiet Start Before the Changes Begin

The day kicks off with a chilly morning at 36°F (2°C), but sunshine will help temperatures climb to 51°F (10°C). It will be a breezy day, and with low humidity, there’s an increased fire risk. Residents should avoid open flames and be mindful of dry brush areas. By evening, temperatures will dip back to 36°F (2°C), setting the stage for a much warmer Friday.

Friday: A Taste of Springtime Warmth

Friday brings a noticeable warm-up, with temperatures climbing to a comfortable 60°F (16°C) under mostly cloudy skies. The evening stays mild at 49°F (10°C), giving residents a brief break from the colder temperatures earlier in the week.

Saturday: Feels Like June, But It Won’t Last

Saturday will feel more like the middle of summer than the end of March. Temperatures will soar to a shocking 79°F (26°C)—the warmest day in months! Expect a warm breeze and partly sunny skies, making it a perfect day for outdoor activities. But don’t be fooled—a sudden temperature drop is coming. By nighttime, temperatures will fall to 40°F (4°C), signaling a major cooldown ahead.

Sunday: The Warmth Disappears as Clouds and Showers Move In

Just as quickly as the warmth arrived, it will vanish. Sunday will bring cooler temperatures, cloudy skies, and scattered showers, with a high of just 53°F (12°C). If you’re heading out, keep an umbrella handy. Evening temperatures will hover around 47°F (9°C), making for a much cooler night.

Monday: Rain, Thunder, and a Temperature Drop

The new week starts stormy, with showers and even the possibility of a thunderstorm. Despite the rain, temperatures will briefly climb to 60°F (16°C) before another cold front sweeps in. By nighttime, expect a significant drop to 47°F (8°C), bringing a chill back to the air.

Tuesday: Back to the Cold – Get Those Jackets Ready!

The warmth is gone, and Tuesday will feel much colder, with a high of only 55°F (13°C). The sun will make a return, but gusty winds will make it feel even cooler. By evening, temperatures plummet to a frigid 32°F (0°C), reminding Long Islanders that winter isn’t fully behind us yet.

Wednesday: A Cold and Cloudy Midweek Forecast

Midweek keeps the chilly trend going, with temperatures struggling to reach 45°F (7°C). Expect overcast skies, and by evening, the low will drop to 39°F (4°C)—a full 40-degree difference from Saturday’s high!
