Here is a summary of the latest NWP output for noon on Tuesday. Issued
0658z, 2/01/04. ECMWF: http://www.wetterzentrale.de/pics/Recm1201.gif An area of low pressure is centred over the Irish Sea, with cyclonic winds for the UK. The low moves away to the east at T+144, although southerlies cover the UK, this time from a low to the west of Ireland. The southerlies continue at T+168 as another low deepens to the west of Ireland. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html A WNW'ly flow covers England and Scotland, with southerlies elsewhere, due to a weak ridge over the British Isles. The ridge merges with a building high over Scandinavia at T+144, leading to southerlies over the UK. GFS: http://www.wetterzentrale.de/pics/Rtavn1081.gif Light westerlies and NW'lies cover the UK, with lows to the west, east and north. The low to the west deepens at T+120, reaulting in SSW'lies and southerlies over the UK, with 850hPa temperatures ranging from -2C over NW Scotland to +4C over Cornwall. The winds become westerlies at T+144 as the low deepens to the NW and there's little change at T+168. By day 8 the low lies to the NE of Scotland, with westerlies and WSW'lies over the UK. The winds become WNW'lies on day 9 due to a weak ridge over the UK, followed by WSW'lies again on day 10 as a new low moves eastwards to the SW of Iceland. GEM: http://www.wetterzentrale.de/pics/Rgem1201.gif The Canadian run shows a ridge over the North Sea, with SW'lies for much of the UK. 850hPa temperatures vary from -3C over NE Scotland to +3C over SW England. By T+144 the winds become southerlies and SSW'lies, with a deep low well to the west of the UK. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html The UK lies under a ridge, with SSW'lies for Northern Ireland, Wales and SW England. The rest of the UK lies under WNW'lies, with 850hPa temperatures ranging from -3C over northern Scotland to +1C over SW England. SW'lies and southerlies from a low to the SW of Iceland affect the UK at T+144, followed by westerlies, SW'lies and NW'lies at T+168 as another weak ridge moves swiftly eastwards. SW'lies cover the UK on day 8, with a deep low to the SW of Iceland. In summary, the models persist in showing a generally unsettled theme, especially for the north and west, for the forseeable future. |
