FAX - HP currently 1037mb Shetland moving steadily SE-wards to Mon 9th 1033mb Black Sea. Weak trough over Channel moving northwards during the weekend as pressure drops over Britain; a more significant depression 984mb developing also by Mon 9th west of Portugal and pushing its fronts ahead towards S England.
GFS Op 00z - the above depression moves northwards only slowly and is off W Ireland Thu 12th. It then gets incorporated into LP moving down from Greenland 990mb Western Isles Sat 14th. That introduces a period of W/NW-lies with LPs following the usual track north of Scotland; 975mb Tue 17th Faeroes and again Sat 21st Fair Isle - from the 14th implies often unsettled for Scotland, passing fronts for England.
ECM - differs markedly from GFS after Thu 12th; that depression off Ireland links with another 980mb Norway, not Greenland, and brings in strong N-lies briefly Sat 14th. After a brief pressure rise from the SW for 15th/16th, depressions develop east of Iceland and run southwards down the Norwegian coast with more cold N-lies for Britain by Fri 20th.
AIFS - London, maxima dropping from 10C now to 6C Sat 14th; after a further drop for a couple of days, back up to 12C from Tue 17th. Rain Thu 12th and Tue 17th. Edinburgh, dropping from 10C now to 5C Fri 13th, unlike London, milder just for the weekend 14th/15th, then a more sustained rise to 10C from Wed 18th. Spits of rain this week, then more definite Tue 17th.
GEFS - mean temp with quite closely clustered ens members, a little below norm to Mon 9th , then 2 or 3C above norm through to Sat 21st. Chances of rain increasing after Mon 9th, heavy in SW and also later in W more generally.
Not surprisingly, GFS and GEFS in step but out of step with ECM and AIFS. A good test for the models.
No review tomorrow (Fri); I have a hospital appointment for a deferred angiogram.
