Models been hinting at this for a while now. Still far too early for any
confidence but a mechanism is becoming apparent. After numerous trough
disruption episodes this month, finally something must give; I see two possible
scenarios:

1. A strong jet propagating east out of Canada, bringing us raging zonality and
mild.
2. A re-alignment of the block further east after a final trough disruption
bringing a Scandi high and a cold easterly.

Probably the final answer will be somewhere in between with the UK in a cold
air/mild air battleground situation, either way I feel that we must eventually
lose this mid-Atlantic ridge and all the northerlies and cut-off lows over UK.

Just a few rambling thoughts for a cold Monday evening!

Will.
