Evens a cold easterly at 10 days. This thread is aptly titled Ronald!

It certainly is. The one model that seems to have stuck to its guns over
the last few days is the UKMO, but that may be because it only runs out
to six days (or at least we only get to see its output that far ahead).
If it went out to 10 days (as in the ECMWF operational run) or 16 days
(GFS), maybe more flips would be evident.

gfs 06z ploughs a milder furrow....., yet it is close to the gfs
ensemble mean right out past 10 days.

Whereas the cold 00z ECM was very much on the colder side of the mean
past next weekend.

Presently we've got the 00z ECM showing easterlies at T240, the 12z
gfs showing easterlies at T240 and the GEM showing westerlies at T240,
with the UKMO showing easterlies at T144. All these 4 are just about
the *exact opposite* of what they were showing at this time yesterday.

This is Olympic class tumbling, never mind somesaults! I don't think
I can ever remember this happening and two up the models (gfs and ECM)
have had upgrades during January. *O

Fascinating, fun and pretty useless for getting a 10 day forecast
correct!
