Nov 10: Monitoring Light Snow Possibility

A weak low pressure disturbance wants to flirt with coastal mid-Atlantic regions shortly after the cold front moves through. Exact timing would be Friday morning, starting before sunrise and ending by early afternoon. It’s important to note that lake effect snow could drop a few flurries in the Thursday-Friday period as well (like last Friday). According to model guidance, coastal New Jersey would have a better chance than interior New Jersey. Again, we’re talking about a possible nuisance event here with disruptive accumulations currently off the table.

Let’s look at some supporting guidance. First is the Canadian model showing pressure, temperatures and precipitation at 850mb early Friday morning. This shows flurries across New Jersey with a slightly higher concentration right along the shore:

Next up is the GFS showing the same time period and model parameters (850mb pressure + temps + precip). The GFS has the system slightly offshore but close enough to fall in line with guidance:

The NAVGEM (Navy model) has the most support for this light event. Same deal…850mb pressure + temps + precip:

The European model shows a solution more in line with the Canadian with precipitation far enough onshore for light snow to fall across New Jersey. Again, this is not a big deal by any means but for many, it could be the first visible snowfall since last winter. It should all fall between late Thursday night and early Friday afternoon…light snow with trace accumulations at most (on non man-made surfaces). As I said in the Monday-Friday Outlook, I’m much more interested in the Sunday-Tuesday period for snow. Be safe! JC
