A decent to significant snow threat exists between Monday, FEB 10th and Wednesday FEB 12th of this upcoming work week.  Models are showing a strong -EPO/+PNA ridge couplet with a strong -AO arctic vortex near Hudson Bay, Canada and a stalled out front along the East Coast of the US.  We don't know the eventual tilt of the short wave trough that comes out of Canada in the arctic jet and we don't know the position of the coastal low and its track or strength.  We don't know the presence of enough cold air to produce snow.  However, this is our first legit shot at something significant.  Stay Tuned!
