Dec 8: Light Snow for NWNJ

Discussion: We’re now under the NW flow that occurs in the upper levels on the back of a trough. A very weak upper-level disturbance, and associated surface low in Canada, is going to send a piece of the energy from the low center towards NJ overnight into Wednesday morning.

This could produce light snowfall for NJ with a strong favoring of NWNJ elevations. The highest elevations of Sussex County always jackpot on events like this. So, for that specific geographic area a few inches of snow are possible. For the rest of NJ in that area (N of I-78 and NW of I-287, anything from a coating to an inch is possible. Once you extend downward into NENJ and CNJ, just non-accumulating flurries is about all I would expect. Perhaps a dusting on natural surfaces. I don’t see much happening SE of the NJ Turnpike/I-95 corridor.

This very light wintry event should move into NWNJ just after midnight tonight and clear out by late Wednesday morning—making 3-8am the most likely hours of snowfall. Here’s the latest expected snowfall map from the HRRR model via WeatherBell Analytics:

In English: Snow is possible for the colder NW regions of NJ Wednesday morning. A light event with only a few inches at most in the highest elevations. Otherwise, a conversational coating more likely NW of the Turnpike in general. Just please consider that many roads will likely be untreated, and it only takes a thin coating to make it slick. Little-to-no issues are expected SE of the Turnpike / S of I-78. Recommend allowing a little more travel time (for those N of I-78 / NW of I-287) between 3-8am. Please be safe! JC
