A Dusting Of Light Snow Tomorrow Night

With cold air pushing in later today, we will see a couple of waves of energy that will traverse the region between the intro to cold and a larger storm system that pushes through the region on Friday (modeled to be a rain and/or snow maker depending on your model).  These small disturbances, one on Monday evening and the other on Wednesday evening, will bring flurries and snow showers around the region.  Monday's has a bit more gas in its tank and will help spawn a stronger storm in the Atlantic that sets up our coldest night of the week on Tuesday night as it draws some additional chill down from the north.

This disturbance, due to having some additional gas (energy) with it, will be able to fire up more than just conversational snow flakes and flurries.  The NAM is suggesting an inch or two could accumulate in some parts of the region as this disturbance moves through tomorrow evening.  It, along with the SREF guidance suite, are the most aggressive.  The Euro, on the other hand, after whiffing away on last week's system is suggesting generally flurries to dusting type snows and the GFS falls in between.

Timing is such that flurries or light snow could begin to fall north and northwest of the city in the mid afternoon and continue in spots until Midnight or just after.  The region is likely in line for at least a few flurries but some spots north of the city will see a dusting of snow to perhaps an inch accumulate.  The best chances for that inch of snow are in elevated hills north of the city.

We'll provide some nowcasting on this forewarned that you may be driving home from work with some light snow or flurries in spots but this won't be a huge deal event.  Just enough to settle some frayed nerves from the snowstarved.
