Nice little bump south on the AI EPS at the height of the mid level warm push compared to 6z.

Anyone have a snowmap for that?

That primary needs to f*** off sooner. Im sweating over here. What model usually does best in these set ups?

NAM wraparound goes forever

Euro EPS look a touch colder than 6z, can someone post the snowmap? It's locked on Pivotal behind a paywall

Trends overall today were for a slightly weaker primary which is good. We don't want it too weak for our area though or we will lose the precip max in SW PA showing up on some models.

Sounds like a tight rope. Expect nothing different for our area. Excited for whatever falls regardless

I would have went with 8 to 12. It encompasses almost all model output.

I told my family days ago 8-14 but also wouldn’t be surprised if it went 12-18

Me too - I would have gone 10-15" north of 287

I'm expecting 10" here but wouldn't be surprised if we get 15". We get there if we get a crazy band or two early, sleet holds off, and there is meaningful backside on Monday

Yeah, not sure what the benefit of being so aggressive is, especially for southern areas of the warning.

Trends today overall look good, just need to make sure we don't lose the uniform precipitation shield.

Overall, I'm expecting about 6-9 inches of snow and sleet here in Staten Island.

Kind of cool for anyone who like big sleet accumulation. NAM has over 1” LE of sleet falling over Colts Neck after 6” of snow. That’s the equivalent of roughly 4” of sleet on top of 6” snow - pretty historic intact if true

The MOAB model finally came to its senses

What this tells me is that our snow maps could be counting heavy snow as sleet. Since they use any 33 degree warm layer aloft as rain.
