NEW: News 12's updated call on snow totals for Sunday's nor'easter calls for up to three inches of snow over the East End, with far less west.

NOW: Bitter cold continues. I know it's tough to believe, but it gets even worse tonight into Friday. Please dress warmly and use caution!

The track of Sunday's storm can still shift slightly east or west. A directional change of 20 to 50 miles would drastically impact snow totals. That said, as of Thursday evening, News 12 is forecasting a trace to 1 inch of snow in Nassau County and western Suffolk County, but up to 3 inches on the East End. If you do not want another major snowstorm for Long Island - and I think we could all use a break following last weekend's storm - recent trends are in your favor. Most computer model guidance has shifted much further east over the last 24+ hours. We do think the far northwestern edge of snow from a big storm positioned around 300 miles southeast of Long Island will still brush parts of Long Island. That is why we are still forecasting some mostly light snow amounts.

It is certainly plausible that this east trend continues. If that is the case, most of Long Island would stay dry with perhaps a couple of snow showers or flurries. We are just not at the time to make a confident call on that yet. The storm is still more than 48 hours from being anywhere near us, and we will have tweaks to the forecast as newer and better information comes in.

The big takeaway from this evening's update is that a major snowstorm on Long Island looks very unlikely. If you live towards and east of Riverhead, though, do not let your guard down yet. Any slight jog west with the storm's track would bump up totals a little over the East End. That just appears to be the more unlikely scenario at this time, but it is absolutely worth watching.

Regardless of snow amounts, even if it trends more dry, strong wind gusts are still expected. Gusts of 25 to 45 mph are possible. There is also a chance for minor coastal flooding and beach erosion, which is exacerbated by Sunday's full moon.

If the current forecast holds, the snow is forecast to begin, especially for the East End, around 3 a.m. Sunday and end late in the day around 10 p.m.

The entire News 12 Storm Watch Team of meteorologists will continue to have important updates on the bitter cold and Sunday's close call with a winter storm on News 12 Long Island, social media and the News 12 APP.

Long Island is also under a "cold weather advisory" through 10 a.m. Friday. Wind chills are around -5 to -15 degrees. A cold weather advisory is issued by the National Weather Service when wind chills are expected to be between -5 degrees and -19 degrees within 24 hours. This is the coldest feeling air of the week, with actual low temperatures in the upper single digits on Friday morning and high temperatures in the teens on Friday afternoon. It will stay dry with a partly cloudy sky, but there will be a biting breeze out of the northwest, around 10 to 20 mph. Stay warm! Frostbite and other cold-weather health issues can begin to appear in as little as 15 minutes.

Saturday continues to look very cold with increasing clouds, but it is the better half of the weekend as we continue to track the potential for minor to moderate impacts from Sunday's offshore storm. Highs will be in the low to mid-20s with lows in the teens through the weekend.

While still cold, it looks less harsh overall. High temperatures will average closer to the low 30s most of the week with mostly dry weather until the chance for snow or mixed showers next Thursday.

Have a great night!
