my browser does not show anything remarkable.
Are you referring to the apparent closely spaced contraflow jetstreams
over the full width of the north Atlantic with a spun up low between
them GFS+300 to +330hr ?

6 am run has the 850hPa temperature below -10C over the entire British
Isles (currently at T+348) and Central England maximum 2m temperature
at -5C. It will soon change, of course.

Having said that, there is a certain degree of consistency between
models and runs as to the cold northerly plunge at the end of next
week - 2 of 3 of the main models at that range suggest that it may
hang around for a while, so that's definitely one to watch.
