The latest model runs suggest that the arctic front that will move through Thursday will be associated with a less amplified jet stream than originally predicted.  That makes the likelihood of cyclogenesis less probable.

That said, some light snow is still a possibility Thursday afternoon.

Of greater interest is still the possibility of some  snow late Sunday, although the energy may split into a secondary low  too far north to truly affect us.  Still needs to be watched.

Tues PM:  There is now little indication of low pressure development along the frontal boundary for Sunday, but it wouldn’t take much for something to develop. An active pattern remains with us.
