Quite a dramatic development in week 2 for pptn on http://www.wxmaps.org/pix/prec4 - yesterday the rain was just for Cormwall, today expect floods for the whole of the UK. Presumably this will keep the cold air well to the NE (but it's still lurking) at bay, at least for now.
GFS - HP hangs around all this week (moves a little to the NW on Fri 5th with brief NE-lies ) but has flattened out by Sun 7th. GFS still can't get a handle on the breakdown from Tue 9th - today's version has well-defined LPs from the Atlantic crossing the N of the UK and stalling over W Russia as they come up against a block by the Urals (Wed 10th 990 mb N Sea, Thu 11th 965mb Hebrides, Sat 13th 980mb E Anglia, Tue 16th 985mb E Scotland, the last trailing N gales as HP blocks the Atlantic)
GEFS - present mild spell ends Fri 5th with quite a sharp dip to cold (5 or 6 C below norm in SE, less marked elsewhere) slowly recovering but staying cool to Tue 16th, and quite good agreement between runs. Rain, small spike Thu 4th in SE and then generally from Mon 8th.
ECM - similar to GFS for this week but runs the first of the train of LPs further south (990 mb Brest Tue 9th and then down to S France) thus at the end of its run looking more like yesterday's GFS .
