I do remember saying it was February and March we needed to look out for with us having an EP La Nina
Februaries - EP La Nina
In EP La Nina years we hit the jackpot for cold in the Februaries. A strong northern blocking signal as well as a split polar vortex unleash the beast from the east onto Europe and the UK. Not only that we see a cold signal for the USA and Canada too under the other half of the polar vortex. If we can get our current La Nina into EP territory, watch this space and look out for what February could bring.
Marches - EP La Nina
EP La Nina years see the northern blocking signal from February carry over although less strong than in Februaries. This results in a colder signal for Europe but the anomaly is likely to be less severe. The cold USA signal also continues on. Between EP and CP La Nina I think CP La Nina is better for the USA cold but EP La Nina can be good for them too.
Summary
Maybe we are now finally starting to see the expected EP La Nina signature with strong northern blocking beginning to creep into the output.
Perhaps we are finally going to see a shift to a proper cold setup
With a number of colder options now showing up in the more extended part of the GFS then maybe the EP La Nina signature for February and March may play out after all and the coldest part of the winter is still to come.
