Here is a summary of the latest NWP output for noon on Thursday. Issued
0601z, 4/04/04. ECMWF: http://www.wetterzentrale.de/pics/Recm1201.html Northerlies and NW'lies cover the UK, with a ridge from a high to the west over Scotland. The ridge moves SE'wards at T+144, allowing NW'lies to cover all areas. The winds become NNW'lies at T+168 as another ridge forms to the NW. MetO: http://www.wetterzentrale.de/pics/Rukm1201.html The Met Office run shows NNW'lies over the UK at both T+120 and T+144, with a large high to the west. GFS: http://64.246.48.81/pics/Rtavn1201.gif The UK lies under NW'lies from a large high to the west, with 850hPa temperatures varying from -4C over Kent to freezing over NW Scotland. The winds become northerlies at T+144 as the Greenland High ridges southwards. The northerlies continue at T+168, but by day 8 the winds are NNW'lies for most as a ridge sinks SE'wards towards the UK. The ridge declines over the UK on day 9, bringing NW'lies for all. By day 10 a deep low lies over the North Sea, with strong cycloninc NNE'lies, NW'lies and westerlies for the UK. GEM: http://www.meteocentre.com/models/glb00_120.html As with the other runs, the UK lies under winds fom a northerly quarter, with NW'lies for Scotland and northerlies or NNE'lies elsewhere. High pressure is located to the west and it declines in situ at T+144; this leads to lighter northerlies across the UK. JMA: http://www.wetterzentrale.de/pics/Rjma1201.html The Japanese run shows a ridge over the UK, with NNW'lies for most. 850hPa temperatures vary from -5C over much of Scotland to -3C over SW England. The winds become westerlies and WNW'lies as the ridge sinks SE'wards at T+144, followed by westerlies at T+168 as a filling low moves southwards over the Faroes. The low deepens again over Scotland on day 8, bringing westerlies for much of the UK. In summary, the models persist in showing a cold spell, with a blocking high to the west steering depressions around the top and down across the North Sea or Scandinavia. The GFS run in particular shows the cold spell to be prolonged, with the UK mainly affected by winds from a northerly quarter all the way out to day 14. |

Are cool wet Aprils often followed by cool wet summers?

Not if 1975 and 1983 were anything to go by.
