We have seen this before, the models showing frequent incursions of polar maritime air with wintriness even at lower levels but as we approach the T0, those incursions move further and further norts and in the end we end up with average or even mild weather. This is because the models have the tendency to overdo the extend of those incursions.
Like other posters have already said, tropospherically, there is nothing promising in the models today.
