I think there was a strong jet stream at 250 leading to pretty intense ascent in that left front quad that enhanced the baroclinically (temperature gradient) driven ascent. They lined up perfectly leading to intense frontogenesis over that area. These west to east relatively weak LP moving off the coast along the frontal boundary reminds me of I think it was March of either 14 or 15 in my area. That same thin narrow band under the “baroclinic zone” out performed every model by 3-5” every time that year. I happened to be under it multiple times that March where my 2-4 ended up 6-8 or a 3-6” ended 7-10”. It was an amazing March to say the least and it was all weak waves along a frontal boundary that just overperformed because of how tight the temp gradient was.

Can finally call a double digit snowfall lol, pathetic. Hoping next week delivers the hammer!
