Expectations for light snow Thursday night on Long Island, potentially switching to rain in time for the Friday morning commute, are still pretty much on target, forecasters say. But specifics on impacts from a more complicated and significant storm for the weekend remain uncertain.
There's the potential for much of Long Island to see 1 to 2 inches of snow Thursday night, with areas of eastern Suffolk County looking at less than an inch of accumulation, the National Weather Service said Wednesday evening. That means travel conditions Thursday night and early Friday could be problematic.
Next up is a “significant storm system” bringing “widespread heavy precipitation, strong winds, and coastal impacts to the region Saturday night into Sunday,” the weather service said.
As of Wednesday evening’s outlook, snow could get started late Saturday evening on the Island, change to rain overnight, with a parting shot of snow or wintry mix Sunday night, the weather service said.
Still, there remains “relatively low certainty” as to specifics on precipitation types and impacts, the weather service said in a hazardous-weather outlook. Details should come into sharper focus over the next 24 to 48 hours, the weather service said Wednesday evening.
Gov. Andrew M. Cuomo urged New Yorkers to be cautious in the potentially snowy and icy conditions.
"All of New York's transportation and public safety agencies are monitoring these storms closely and are prepared to immediately assist any community that needs help," Cuomo said in a statement.
Temperatures Sunday are expected to rise into the upper 40s in the morning before plunging in the afternoon and nighttime hours to 12 degrees or so, as arctic air rushes into the region, the weather service said. And that means potential for a flash freeze Sunday night.
Monday, Martin Luther King Day, sees temperatures rise to around 20 degrees, then dip down overnight, again, to around 12 degrees.
