Default Seasonal forecast

North Atlantic sea-temperature anomalies show a large cold pool SE
of Newfoundland. For the next few months this would seem to point to the
jet stream being further south than normal and also would back a
negative AO. Putting detail on this for the UK is a bit of a mug's game
but . . .

El niño forecast is broadly negative - I know this has little to do with UK but there must surely be some correlation with long wave global patterns etc. On closer investigation of the figures two singularities emerge - 1962 and 1981 - both summers were poor overall but not without decent warm intervals - August 1981 was very pleasant at times, at least in the SE. So perhaps we're in for a yo-yo summer?

We've actually got ENSO neutral conditions Scott and the forecast from NOAA is trending slightly positive over the Boreal summer and for the rest of this year, though ENSO is slightly negative now:

Aussie BOM says the same:

I'm always interested in your use of Atlantic SSTs for longer range prediction of UK seasonal weather. Have you kept records of your observations prior to seasons your prediction and its accuracy?

You might be interested in this, but the warmth here appears to be restricted to the continental shelf:
