Forecast models shift snowfall for Tuesday night into Wednesday morning further inland

    Afternoon forecast models have shifted snow from the northwestern fringe of a storm that will pass well offshore tonight and early Wednesday morning further inland. 

    Forecasters have been monitoring the threat since last Friday, when one forecast model indicated a glancing blow to southern portions of New Jersey. But beginning Sunday, more forecast models began converging on a northwest trend, increasing snow chances, especially in southeastern areas. 

    total snowfall accumulation map issued by the National Weather Service office in Mount Holly, NJ Tuesday afternoon depicts the heaviest snow in a line from central coastal Cumberland County to central coastal Ocean County (2-4″), with lesser amounts to the north and west (1-2″). The snow shield extends to the NJ Turnpike corridor, where areas to the immediate northwest and southeast of the highway could see an inch or less. 

    “Snow should overspread the area generally from south to north early this evening, then taper off toward daybreak Wednesday,” a Winter Weather Advisory for Cape May and Atlantic counties advises. “Roads will become snow covered and slippery due to temperatures well below freezing and accumulating snow. Travel conditions will become hazardous.” 

    The takeaway: most of Central Jersey and all of South Jersey is expected to see measurable snow, with the highest amounts in southeastern areas.

    Forecasters could bump the Winter Weather Advisory further north and west later today if model guidance continues the northwestern storm progression.
