In this case 1 degree is everything from the GFS for Sunday. After 09z 0.5-0.75" falls on my head at 33F in a very ice storm looking sounding. While that amount of QPF likely wouldn't bring the grid down, it would make things a hazard.
Beware the dryslot around sunrise tomorrow in CT? Potential for a nice Kraft/Tucker/Watson in eastern areas as mid-levels close off? Should be fun for all and leaves plenty of time to clean up before the game.
