Cold seems pretty lodged in as the -NAO exerts some influence.

NAM3 trend

Starting to be a little more.optimistic back this way for this one... lots of time to reverse the positive trends tho.

Yeah, our pessimistic posters haven't chimed in, they are waiting for the rug pull.

Trending colder at 850

This is as precip is coming down heavier.

The problem in EPA is that there is a warm nose 800-750mb.  So when you don't see it above freezing on 700,850 and 925 layers but sleet or mix is showing up, check the skews.

That's actually heavy snow down by @Miller A. Wet, sloppy, warm, heavy snow. Might be the heaviest on the scale.

Column is cold until you hit near the surface... which is 35 of course.

Close to isothermal just below freezing, from H7 to close to the surface can produce good rates. Might pack itself down.  Power outage stuff.

A good look at the speedy flow between the Hudson Bay vortex, and the western Caribbean ridge.

After staring at this for a few minutes, I now feel like I should use this view more. You can kinda see how systems moving west, along the southern edge of the ridge, erode the western edge, as it rounds to the north.  These brief erosions look like the best storm windows.

It's intriguing how consistent Boston-ish area is being bullseye'd the past couple days.  I'd be sad if I was them, b/c we all know how it USUALLY works out beging 4-6 days out.  Now... where will it actually bullseye .. farther south, or father north?

It would be funny if the Poconos ended up the jackpot.

Hour 57 SREF comp to last run.
