A weak low-pressure system is expected to cut across the midwest on Monday, January 25 along a rather zonal flow. Onshore winds, associated with strong high pressure to the north of our area will help funnel in some arctic air sitting in eastern Canada. Temperatures should start off on the cold side during late Monday night into the wee hours of Tuesday morning, when the precipitation is expected to enter New Jersey. As the low begins to transfer offshore, temperatures will warm up, and change any snow/mix to rain in southern New Jersey up into central New Jersey. Some areas may change back over to snow as the low exits out to sea, as colder temperatures get pulled into the state.
Currently, the best chance for an all snow event appears to be areas north and west of I-95. Those south and east of I-95 will likely start off with snow before changing over to a sleety mix and/or rain as the low moves from the Pittsburgh area to off the Delmarva Peninsula. Cape May County and the immediate coastline up to Ocean County will likely stay all rain due to the Atlantic Ocean’s influence. The precipitation should start wrapping up late Tuesday afternoon into the evening hours. For those north of I-95, this looks to be a plowable snow event, but nothing crazy.
