That one's a little tight but the potential is there. Tip is saying 78 is coming. It's all good, @ice1972's inebriated melt last night is already pumping heights in the northeast and will result in North Atlantic blocking in about 10 days.
3) higher likelihood of a northern stream s/w acting as a kicker vs if the shortwave originates from it and just pulls in southern moisture
I can do okay in both but I'll take my chances with the mid level magic of a Miller B on the whole
