NAM looks pretty flat through 30. Worse than 12z even (and that was a southern outlier). Wouldn't be surprised if this run is almost a clean whiff save maybe the south coast. NAM has literally been all over the map the past 24 hours...pretty ugly yesterday at 18z, widespread advisory (or even low end warning in spots) at 00z...a little less wild, but still decent at 06z...suppressed at 12z, and now probably almost a whiff at 18z.

As good as a winter as it's had.. the last 3-4 weeks it's struggled. You wonder if it struggles during transition season
