Euro continues to open the freezer in the long range. Man just give us some snow covered ground and it'll be a cold shot to remember.

Euro has a decent vort max over Minnesota, the GFS does not. Seems to interfere with the coastal low.

Clear west trend on the Canadian

Looks like the 12z UKMET was better for northern areas?

Yes. That's excellent. Looks like light snow back to the I-81 corridor on the mean.

UKMET did too?

The Reno upper air site sampled a record western ridge at 591dm. That ob was in place for the 12z model suite, and voila...everything tucks closer to the coast. Do not underestimate the importance of upper air data beyond HR90.

IMO, if the 12z suite tomorrow has this or better, then we are likely onto something.

Trough has progressed further west each run, and this is not isolated to the GFS. The Euro, Euro AI, EPS, and UKMET all have this in some fashion. It certainly looks like most of the Delaware Valley could be falling into a light to potentially moderate weekend snowfall.

Going to be very interested in the GEFS. If the snowfall mean ticks up, then we might be onto something here.

What rule is this?
