N.J. weather: Ice storm on the way, with possible thunderstorms. Latest forecast, timing, warnings and advisories. Updated Feb 16, 2021; Posted Feb 15, 2021 Facebook Share UPDATE: Another wave of wintry weather is on the way to New Jersey, with a combination of light snow, sleet and freezing rain expected to arrive Monday night and eventually change to plain rain before it ends early Tuesday morning. For some parts of the state, this could turn into a nasty ice storm — with freezing rain turning roads and sidewalks into dangerous sheets of ice, forecasters say. That’s why the National Weather Service has taken the rare step of issuing an ice storm warning in six counties: Hunterdon, Morris, Somerset, Sussex, Warren and western Passaic.
