LONG ISLAND WEATHER ALERTS: A wind advisory is in effect for Nassau and Suffolk Counties until 12 a.m. Saturday. A coastal flood warning is in effect for southern Nassau County and southwestern Suffolk County on Friday morning. A coastal flood advisory is in effect for southeastern Suffolk County on Friday morning.
Plan ahead for extra travel time and use extreme caution when traveling this morning. Airports may see significant delays and driving can certainly be problematic in the morning.
There will be periods of moderate to heavy rain, a chance of a thunderstorm, potentially damaging wind gusts and coastal flooding along the south shore. This may occur during high tide in the morning from around 6 a.m. to 11 a.m.
It is simply going to be a rough morning of weather on Long Island on Friday. Temperatures will not be an issue early on - highs will occur in the morning in the upper 50s with the wind and rain. There is a chance that a new record high temperature will be set in the morning.
Once the afternoon arrives, the weather will quiet down a bit. Steady rain tapers off to just a few spotty showers, and the strongest of the wind will start to diminish. That said, gusts between 30 and 45 mph will still be possible in the afternoon, leading to additional scattered power outages. It will also start to feel colder quickly.
Temperatures will quickly turn colder into early Friday evening. The strong wind will help dry the ground, but any lingering standing water in the evening can refreeze. This means areas of icy conditions will be possible through early Saturday morning.
On top of that, temperatures will feel as if they are in the teens on Friday night.
The weekend overall will be nice ahead of another very cold start to next week. As of now, there are no major travel concerns weather-wise ahead of the holidays, but some light mixed rain and snow showers are possible on Tuesday. Christmas Day can also have a few rain showers late in the day, but no major storms are expected next week at this time.
Have a great night and be sure to stay with News 12 all day on Friday for the very latest Storm watch forecast and live weather conditions in the morning.
