And so it (snow watch) begins!
We're on the board now with some Euro ensemble members starting to show snow on Long Island within the next 15 days (see 1st image, which shows projected snowfall for the next 15 days as a running total from every Euro ensemble member). It's still highly unlikely to happen though, but 6 of the 51 ensemble members are showing snow. For Boston, 11 of the 51 members are showing snow.
The 2nd image shows the projected snowfall for the next 15 days from the Euro ensemble mean, which takes the average of all of the ensemble members.
The 3rd image shows the ramp down in temperatures for Long Island for the next 15 days from the Euro ensembles.
