Shoot me for saying this - but the NAM evolution actually makes sense.
GFS is a minor event for anyone Harrisburg and N/NW. It’s been incredibly consistent with keeping good snow south of the border.
Might be my mind doing tricks - and I don’t know where verification scores are - but hasn’t the old school GFS kicked the tail of the other models this season?
... back to the weather.
At a quick glance it appears the 12z models lost basically every snowmaker potential for the next week. Cutters but I don't see any cold air to help it not rain.
Went out and cleaned up during the dryslot moment. I’ll call this 4.5” snow and .3” sleet. Really nice storm -would’ve been perfect had we been able to hang on to the cold air in the atmosphere through noon.
Like MAG said the ENE wind is chilly!
