So the provisional Hadley CET is now a whole degree Celsius above my local mean... I am not amused.
Using 3.5*C to 18th as a starting point, the 12z GFS produces a final CET of around 3.8*C.
Allowing for adjustments to the CET it could be as low as 3.6*C but I'm not counting on it. A 1.0*C error is not bad going for the model + signal projection I suppose, though it looks like using a model + LTA combination (i.e. just going for an average second half of the month instead of applying a cold or warm anomaly signal) would have landed closer.
I wonder if March will have a clear signal one way or the other by the final days of this month. At the moment, longer range tools keep switching between high latitude blocking and a strong Azores High extending across the south of the UK... two opposing extremes!
