The National Weather Service (NWS) has continued their winter weather advisory for tonight into early Tuesday morning. I’m expecting precipitation to break out over western New Jersey this evening from 7 pm – 10 pm. It could start out as a cold rain in some areas. Then the rain will cool the atmosphere a little more and the rain should mix if and possibly change to sleet for a few hours. Further to the north and west (near and north of I-80), especially in elevated areas, there could be some wet snow mixed in as well.
Warmer air will eventually take over and we should see all rain by the Tuesday morning commute. The changeover will take a bit longer further to the north and west. Given how warm the ground has been recently I expect little of any accumulation. At most there could be a little slush on colder surfaces like cars.
The most important thing to keep an eye on tonight is the air temperature. As long as we remain above freezing the roads and walkways should be fine. Bit some areas further to the north and west, as well as sheltered valleys, may have pockets of colder temperatures. In these areas we might see a little bit of freezing rain after the switch-over until the warmer temperatures make it to those areas as well.
I’ll have additional updates as warranted.
