SUNDAY COASTAL WINTER STORM UPDATE: All eyes are on what will be a big winter storm developing over the weekend, but there is still a question about how it will impact Long Island.

ALERTS: The National Weather Service has issued another "cold weather advisory" for Long Island midnight through 10 a.m. Friday. Wind chills around -5 to -15 degrees, be safe as the dangerous cold air continues to impact Long Island. A cold weather advisory is issued when wind chills are expected to be between -5 degrees and -19 degrees within 24 hours.

Today: Mostly sunny, with a high near 22. Wind chill values between -5 and 5. Northwest wind 10-20 mph.

Tonight: Mostly clear, with a low around 8. Wind chill values between Zero and -15. Northwest wind 10-20 mph.

Friday: Sunny and cold, with a high near 18. Wind chill values between -5 and 5. West wind 10-20 mph.

Friday Night: Partly cloudy, with a low around 5. Wind chill values between zero and -15. Northwest wind 5-15 mph.

Saturday: Mostly sunny and cold, with a high near 20. North wind 5 to 10 mph.

SUNDAY FORECAST TRENDS: While we are still watching the trends with computer model guidance, there is a noticeable "lean" east now, keeping the worst of the storm offshore. That said, we can still get a couple of inches of snow on Long Island, with several inches possible over the east end of Suffolk County. It could end up that Nassau County gets a coating to a couple of inches of snow, while eastern Suffolk County gets 4 inches or more. That is how close of a call this is, but the trends are for less of a major storm in terms of snow totals area-wide.

OTHER POTENTIAL IMPACTS: Strong winds can still be a factor, regardless of how much snow Long Island gets on Sunday, with 20 to 45 mph gusts possible. There is also the chance for minor coastal flooding and beach erosion, which is exacerbated by Sunday's full "Snow" moon.

WHEN WILL WE KNOW MORE? The News 12 Storm Watch Team will have enough information to make a first call on snow forecast totals throughout the day on Thursday, with higher confidence forecasts each day leading up to Sunday. Please check back for the latest updates!

BEYOND SUNDAY'S STORM CHANCES: The weather into next week looks to be slightly less harsh-feeling than this week. It will still be cold with high temperatures in the upper 30s to low 30s and nighttime lows in the teens to low 20s. Our next chance for at least snow showers after Sunday looks to be next Thursday.
