Tracking Jan 7 coastal storm. Lingering compression/flow velocity has not lent to consensus, but it seems at 30 hours out.. finally?

Very strong cross-ensemble agreement of signal for a coastal 4-5 days out. Do not live and die by the vicissitudes of the operational runs, because we have like 3 "trends" to go before game-time. This system is also an emergent of a jet displacement on the west coast resulting in a +2 SD change in PNA value, so it has strong synoptic support.

I was going to say that I think everyone agrees in the formation of some type of coastal system, but then, you know, Kevin.

The benchmark is 75 miles se of Nantucket right? Looks to me like on most guidance the low is well NW of that. If anything it’s going to be rain snow lines that are the issue, not the storm being too weak or far south based on the current guidance.

Due south 40/70
