Stormy Friday night, windy and much colder Saturday. Frost possible on Sunday morning.

Cloudy skies and scattered showers will make for a wet start to our Friday across Long Island. Expect some rain during the morning rush hour and while getting the kids off to school, so allow a little extra travel time. Showers should continue through about 10 a.m. or 11 a.m. before we catch a midday break. We could even see some breaks of sunshine during the afternoon, helping temperatures climb into the upper 60s and lower 70s. Enjoy that brief improvement because another round of wet weather is heading our way. Have the umbrella handy.

Friday evening and overnight will be our main weather concern as a strong cold front moves across Long Island. After 5 p.m. , scattered showers and thunderstorms will develop, and some storms could become strong. The main threats will be heavy downpours, strong winds and gusts around 40 mph, especially with any stronger thunderstorms. Keep an eye on the weather if you're heading to a high school football game or have other outdoor plans Friday evening. The greatest threat for thunderstorms will be through midnight. After midnight, scattered showers and periods of rain will linger into early Saturday morning. Much colder air will rush in behind the front, sending temperatures tumbling into the 40s by daybreak.

Saturday night will be a cold one as skies clear and temperatures take another tumble. Overnight lows will drop into the 30s across much of Long Island, setting the stage for a chilly Sunday morning. Some of our colder inland locations, especially around the Pine Barrens and eastern Suffolk County, could see patchy frost. The frost potential will depend on how quickly the winds diminish overnight, allowing temperatures near the ground to fall. If you still have sensitive plants outdoors, you may want to take precautions and protect them from the colder temperatures.

The good news is that Sunday is shaping up to be a beautiful fall day, just on the chilly side. We'll enjoy plenty of sunshine throughout the day, with afternoon temperatures reaching the mid-50s. That's below average for the middle of October, but at least we'll have dry conditions for pumpkin picking, fall festivals or enjoying the changing leaves. The big weather stories this weekend will be Friday night's potentially strong thunderstorms, Saturday's gusty winds and nearly 20-degree temperature drop, followed by the possibility of patchy frost Sunday morning. After a stormy start to the weekend, we'll finish with plenty of sunshine and some crisp fall weather.
