Blizzard of 2026 Storm Thread/OBS

So far it looks like the 6z runs have reduced snow totals compared to prior runs. Heavy returns seem to be staying up north more. I'm don't have the ability to post maps. Still looks like a 8-12 for the metro Philly area and more towards the shore

MQS range between HRRR and NAM is identical to our upgraded winter storm warning of 16-22”. Sounds like a solid call at the moment. Now just gotta pull the trigger on the blizzard warning - make it official.

I am kind of real surprised that the winter storm warning for places like Lehigh/Berks has been upped to 10-20in of snow. I think they must real be buying into these short range mesos

Mt. Holly's latest just before 4 am -

Wanted to start adding some obs since there has been some light liquid precip this morning IMBY.  Currently some intermittent light drizzle (not enough to tip the bucket but walks and streets are wet) and 37, with dp 34.

Kind of surprised there isn’t more of a concern in this sub about the gradient on the west getting even tighter and shifts east. Unless it’s just more nowcasting than anything
