Mid-month is very interesting. As tip alluded to yesterday, that 500mb features lots of shortwaves digging and amplifying slightly south of Long Island...you keep feeding a constant supply of shortwaves and something is bound to give. I will say though and I know this leads to debate, but I would feel MUCH better if we had some southern stream involvement. If there was some southern stream feeding energy we could probably say the odds are almost certain something would happen.
