Jetstream still running strongly close to UK but for much of the period to the south. That suggests a mobile rather cold pattern and snow on hills with lower ground seeing sleet or a quick dump of wet snow. 200+mph streaks today & Thu 5th. Some big loops developing Mon 9th with the UK under a section of the stream directly from the north.
http://www.wxmaps.org/pix/temp4 shows below zero day-night averages picking out high ground in W Europe.
GFS has westerly flows with LP centres crossing the UK and mostly pulling in some polar maritime air behind Tue 25th, Thu 27th, Sat 29th, Tue 3rd, Thu 5th, Sat 7th - doesn't come more unsettled than that! Finally a ridge of HP on Tue 10th with the caveat that GFS has been showing this in previous runs but at progressively later dates.
ECM agrees though tending to place the centre of the LPs towards the north of the UK
GEFS ens generally wet (if anything, the focus moves south) and temp a couple of degrees below the seasonal norm. Snow row figures mid-teens for the north but even the south has a few high values in today's runs.
