As Joe noted the phasing of this system is what will make or break it. My concern is the northern stream being quicker and suppressing this into a sheared out mess. That said the Euro has been very consistent on timing and this isn't that far away either.
This looks like a pretty solid hit and unlike this last Wednesday this system is going to be under a process of strengthening. Kind of reminds me of the system back in mid January in that regard.
Thinking this is more of a 3-5" locally vs the original thought of 4-7". Wouldn't shock me if someone ended up close to 6 but I think we stay just a bit under that.
The Euro/ukmet would be a good hit for both Detroit and Chicago as Chicago would make up with lake enhancement/lake effect to counterbalance the lighter synoptic amounts.
NAM run to run is trending with slower more neutrally tilted trough with a faster northern stream piece across Ontario. It could be complete BS but that is one positive trend in a model today.
