18z DT GFS
 

It's started to come through now and continues to show the trend
of a N wind veering NE. The upper ridge to the W is thrown
further N at T+144/156, Miles' Extension ?

Joe (or anyone else)
Could you tell me what exactly a Mile's extension is please?
I heard it mentioned last winter sometime by Will.

I notice 18z is very different, but still very cold - the low in the
Norwegian Sea seems to be the main difference...very interesting!

Ta,
John

The Scandi High has gone east though, so no screaming easterlies :(

Hi John,

Mile's extension is a plunge of cold air south over the UK in response to
warm
advection north over Greenland. I'm sure Will can explain better. Sadly
Google
brings nothing up on the subject.

Ok - thanks Joe!

Joe - there is a clear consistency developing in the models now. Here is
the GFS 850mb 18z chart for Sunday:

Not on UKMO for Fri/Sat/Sun it hasn't... it has HP pushing W into
Scandi and it's developing cold Easterlies over the North Sea.
