FWIW, From Bernie Rayno, great Accuweather meteorologist:
“BTW what you are seeing in modeling with minor changes is classic WINDSHIELD WIPER EFFECT..Stay in the middle and don't get pushed around. The overall pattern and snowstorm is unchanged”
Seems like sound advice. Here out on far NW fringe of storm, I am just pulling for something memorable to play out in ENE. Enjoy.
