Will normal service be resumed by next week?

According to the latest run of the GFS a positive zonal flow is returned by the middle of next week (T+192). 

It's always wise to treat anything beyond T+120 with a healthy dose of skepticism no matter what model you're looking at, so make of it what you will

More science fiction - the low following that one introduces some cold northerlies before tracking SE across the country, and lo and behold we have another potential block, with high pressure not only building over Scandinavia again, but another one sat in mid Atlantic right where those negative SST are.

It's a shame that Wetterzentrale don't keep a longer archive of the NWP images that they generate but they did get it vaguely right, the block was broken temporarily before it's remade again.
