  1. One thing I can tell you about the 18z 3k NAM is that it indicates about a 6 hour period in NYC and surrounding areas of moderate to heavy snow Saturday night before any mixing issues. Even at 04z NYC is at 33 degrees but soundings show the column below freezing so it would still be snow. After 05z there’s a warm nose around 750mb which would cause sleet to mix in.
  2. Sunday is going to be a nowcasting event and has tremendous bust chances in both directions. Even if it worked out verbatim like the GFS/NAM show it’s still going to come down to exactly where and when the band pivots. We shall see if confidence increases the next two days. Still lots of time to go.
  3. If you’re looking for more than a sloppy couple of inches we will need stronger dynamics to help cool the BL. Still you’re looking at 33-34 degrees in the city during peak intensity. The better hope is that Sunday materializes.
  4. I’m a little surprised with how consistent the models have been this far out with the potential for this weekend. There’s a well positioned high and blocking which obviously opens the door for suppression. It looks like the heaviest snow will be interior Eastern PA and the mountains NW of DC and BWI. The 00z Euro is less suppressed looking than the GFS. Looks like there will be a sharp cut off either way around I-84.
