Energy “crashing into the west coast” can go both ways. It can keep a system from cutting too and they can also temporarily amp up the ridge downstream of it…it all depends how the trough hitting the west coast is behaving. If it is n the process of digging, then it will help amp the ridge ahead of it, if it’s in the process of weakening, then it will act more like a kicker.
A lot of big dogs had energy hitting the west coast…Jan 2016, Feb 2013, Boxing Day 2010, Feb 2001, Dec 1992….those are just the ones I know. But there are likely others too.
We don’t know if it will help or hurt yet. It’s one of those nuances that isn’t really known at this type of lead time.
