A lot of uncertainty with how far east the low gets next weekend... all bets are off in terms of how warm it gets and whether the northwest escapes the rain! Usually with the MJO behaving as it is, I'd favour the low stalling out further west as per UKMO and GEM's 12z op runs, but with the unusual SST situation in the North Atlantic, I'm wary of the jet continuing to pack a bit more of a punch than usual.
Beyond that, changes in tropical forcing suggest that we should keep an eye out for the next low digging down to our SW, but as yet the models seem hesitant to try out that idea. They often struggle during times like this, as the balance of power adjusts by the day.
Yet again though, the N. Atlantic cold pool may prove to be the spanner in the works. We're in unfamiliar territory these days!
