Soon after Governor Phil Murphy declared a State of Emergency in response to the encroaching winter weather-laden storm, school districts began delaying and canceling instruction for Tuesday.
Executive Order No. 406 set the State of Emergency across Hunterdon, Morris, Passaic, Sussex, and Warren Counties.
“Starting early tomorrow morning, we will experience potentially significant winter weather resulting in hazardous conditions in the northwestern part of our state. With snowfall, sleet, and freezing rain expected to impact travel and safety on our roads, I am declaring a State of Emergency for Hunterdon, Morris, Passaic, Sussex, and Warren Counties,” said Murphy. “I urge all drivers in these areas to exercise caution, remain alert, and follow all safety protocols.”
Those corresponding regions reacted swiftly with these changes for Tuesday morning:
Snow accumulation forecasts decreased in a Monday afternoon update by the National Weather Service, though the risk of freezing rain has increased, according to the National Weather Service. Sussex County's warning was downgraded and now joins Warren, Morris, Hunterdon and western Passaic counties under a Winter Storm Advisory.
Three to 6 inches of snow are forecast for Sussex County; the other impacted counties are expected to get 1 to 2 inches of snow, turning into rain by midday, according to the National Weather Service. This could result in a light glaze of ice and make for slippery road conditions.
The rest of the state will get a few flakes, quickly changing into rain. Weather-related impacts here are not expected.
The counties under a Winter Storm Advisory are "most likely to experience a troublesome Tuesday morning commute," the National Weather Service said. As snow will be falling during the Tuesday morning rush hour and it being the first widespread snow of the season, even a smaller amount of snow could have strong impacts.
Conditions will dry up through Tuesday night. However, lows Tuesday night will be in the 20s for most, so there could be some black ice where slushy snow melts and refreezes.
Temperatures will remain frigid through the rest of the week, forecasters said. More snow showers are in store for North Jersey Thursday into Thursday night as a cold front passes.
By Friday, another winter storm is possible. However, it's too early for any details to be nailed down.
