http://www.wxmaps.org/pix/prec4 copious rain for the next two weeks, not just the amber warning for the north on Wednesday; and the Siberian cold has wimped out.
GFS = LPs moving across from the Atlantic, particularly deep 960mb NE Scotland Fri 22nd with a brief spell of N-lies to follow; then back to the Atlantic conveyor throughout (the most S-ly of these LPs runs across the UK Fri 29th 985 mb NI).
FAX shows LP this week a day earlier i.e. Thu and deeper 950mb with lots of frontal rain preceding it.
GEFS - mild now (near norm in Scotland), cool Thu 21st to Tue 26th with good agreement. Thereafter a suggestion of mild at first and cooler later but much variability in different runs. Rain throughout -yesterday's forecast dry slot ca Sat 23rd has been squeezed out at least for the S.
ECM - similar to GFS at first but inclined to keep N-ly flow for longer after Fri 22nd, perhaps as long as Wed 27th
