That boundary is tight. GFS was actually a little colder than 12Z, but didn’t extend the wave of precip as far into Friday. But it largely held serve.
The NAM wasn’t anything great for us, but does get a raging sleet storm pretty close.
Still think this feels like big hit for NW PA/NE OH. My glimmer of hope is that I have seen the rushing of cold air undermodeled here, similar to the way warm air advecting often is.
