RECORD WARMTH POSSIBLE

MH_RECORD_HEAT.png

Enjoy another taste of summer today because a big change is coming our way! Temperatures will climb into the 70s to low 80 degrees, putting us in record warmth for the middle of October. We'll have a mix of sun and clouds, along with a little humidity. A few showers this afternoon and with some thunderstorms. Have the umbrella for the quick downpours. Overall, it's another warm October day across Long Island, but much colder weather is on the way for the weekend.

Long Island Today forecast

A cold front will move through tonight, bringing partly cloudy skies and a noticeable drop in temperatures. Overnight lows will fall into the lower 50s as cooler, drier air settles into the region.

Long Island tonight forecast

Thursday is shaping up to be a beautiful fall day, with plenty of sunshine, lower humidity and afternoon temperatures ranging from 60 to 65 degrees. It will be cooler than today, but still a pleasant day to get outside and enjoy the fall weather.

Long Island tomorrow forecast

Our next weather system arrives Friday, bringing cloudy skies and scattered showers throughout the day. Temperatures will remain relatively mild, with highs in the upper 60s and lower 70s. The bigger story comes Friday night as a strong cold front moves across the region. Showers and possibly a few thunderstorms will accompany the front, followed by increasingly gusty winds and a surge of much colder air. Wind gusts could reach 35 to 40 mph overnight, with temperatures tumbling into the lower 40s by Saturday morning. Showers should move out and skies will begin clearing toward daybreak.

Saturday will feel dramatically different from today's near-record warmth. We'll have mostly sunny skies with a few passing clouds, but it will be a cold and blustery day. Afternoon highs will struggle to reach 50 to 55 degrees, and northwest winds gusting 30 to 40 mph will make it feel more like the 30s and lower 40s at times. You'll definitely want the heavier jackets if you're heading to pumpkin patches, fall festivals or other outdoor activities. Winds will gradually diminish Saturday night under mostly clear skies, allowing temperatures to fall into the 30s across many inland neighborhoods. Some patchy frost may develop in the colder spots, especially around the Pine Barrens, if winds become light enough.

Sunday is looking like the better half of the weekend for outdoor plans. We'll have plenty of sunshine, and while temperatures will remain on the chilly side, the winds will be much lighter than Saturday. Afternoon highs will generally reach the 50s, making for a crisp but pleasant autumn day. The big weather story is the dramatic temperature swing, going from near 80 degrees today to wind chills in the 30s by Saturday. It's a reminder that fall is here, and this weekend will certainly feel a lot more like October than summer.
