From record-breaking warmth to a chilly, windy weekend, Long Island is in for quite a temperature swing! After reaching a record high of 82 degrees Wednesday at Long Island MacArthur Airport, we're back to more typical October weather today. Expect mostly sunny skies with afternoon highs in the lower 60s. That's a drop of about 20 degrees in just 24 hours, but with plenty of sunshine, it should still be a nice fall day.

Long Island Today forecast

Clouds will increase tonight, with skies becoming cloudy by midnight. Scattered showers will develop toward Friday morning, with overnight lows in the upper 40s and lower 50s. Friday starts with some rain, followed by a midday break and even a few hints of sunshine. Temperatures will climb into the upper 60s and lower 70s before another round of showers and possible thunderstorms arrives Friday evening.

Long Island tonight forecast
Long Island tomorrow forecast

A strong cold front will move through Friday night into early Saturday, bringing showers, possible thunderstorms and increasingly gusty winds. Temperatures will tumble into the 40s by Saturday morning. An early shower is possible, but sunshine will return for much of Saturday. Don't let that sunshine fool you! Highs will only reach 50 to 55 degrees, with wind gusts of 30 to 40 mph, especially during the morning. If you're heading to the kids' sporting events, you'll definitely want the heavier jacket. The wind will make it feel even colder.
