Some guys on phillywx have tracked the threshold on the EPS (let alone the weeklies) where a snowfall mean actually means it will snow. Minimum is usually 2-3”, but typically more like 4-5”. And that’s within 2 weeks, not 6.
Thanks for checking in DT.
I’m not sure about the Nina intensity, but I do agree that the very warm NPAC coupled with the Nina is pretty unusual and may throw a wrench in things.
