ECMWF: http://64.246.48.81/pics/Recm1201.gif Moderate SW'lies cover the UK as the result of a deep low near Iceland and a high over Germany. The SW'lies become lighter over England and Wales at T+144 as a small high forms to the SW, followed by SSW'lies for all at T+168 with a trough to the west. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html The UK lies under WSW'lies and SW'lies, with lows to the north, NW and west. SW'lies continue to affect the UK at T+144 with lows persisting to the north and NW. GFS: http://64.246.48.81/pics/Rtavn1201.gif A deep low lies to the north, with high pressure extending from the Azores to the Alps and beyond.

A secondry low crosses the UK at T+144, followed by SW'lies from a low west of Ireland at T+168.
