3/20/15 perhaps? Not sure if it was a clipper...but my records show 4.1". Looks like a Friday afternoon/eve event.

I cant remember much, party days gone wrong. but it wasnt that late in the season. Wait, its not 2015 it was 2014 in Feb maybe? an Arctic clipper that put down warning snows for most in CT during pm rush. I had to pull off the Merritt before the tunnel.

Well, that's not a great hill to be on in heavy snow. I don't blame you.

Euro looks decent.

Yeah still a bit paltry on QPF, but better than 00z....the shortwave def looked pretty good to me. Has a little kink in it and travels near LI and ACK.

 

Round 2 looks pretty good along and N of pike especially. That has some sneak potential because of the lapse rates....

Yeah who knows where he gets this stuff from.

Ask Hayden at BOX.. are you saying he was wrong?

Otherwise Wed, high TT (above 50) and decent lapse rates across
the interior with the arctic wave passage is likely to yield brief
mod SHSN across interior S New England when combined with incoming
moisture from the active Great Lakes. LLJ 40+ kt also suggest
brief squalls, with heavier winds, some whiteouts and rapid accums
possible. Temps are still above seasonal normals as H92 temps only

Kev, I do not see any Arctis squalls Wed afternoon and you know me and Windex

Well Ryan highly respects Frank and thinks he's the best of the best at BOX.. so either he is outright saying he's wrong.. or just missed it as he was diagnosing the models

There are steep lapse rates on Wed.
