The GFS has been quite inconsistent with the  development of low pressure in the Sunday through Monday timeframe.

The latest trend is for low pressure to develop and move over the Great Lakes, keeping us in the warm sector.  So while some light snow or mixed precipitation is possible at the start Sunday afternoon into evening,  a changeover to all rain on Monday is likely.  Little or no accumulation expected at this time.

Still unclear whether a secondary low will form off the coast on Monday with a change back to some snow towards the end of the day.

After a brief relative warmup with wet weather on Monday, another outbreak of cold air expected  next week.  The pattern remains cold and active.
