Default Today's model interpretation (20/10/10)

?Here is a summary of the latest NWP output for noon (GMT) on Sunday. Issued
0426z, 20/10/10.

Next week is likely to start with NW'lies across the UK, with showers
especially in the north and west. Thereafter all the models except GFS bring
milder westerlies, with GFS instead prolonging the colder conditions.

ECMWF: http://www.wzkarten.de/pics/Recm1201.gif
Low pressure lies to the NE, with NW'lies for all as a result. A ridge moves
eastwards on day 6, with WNW'lies covering the UK. WSW'lies affect all areas
on day 7 as a trough moves eastwards in association with a low to the north.

MetO: http://www.wzkarten.de/pics/Rukm1201.gif
The Met Office run brings NNW'lies due to a low over the North Sea. As with
ECM, a ridge covers the UK on day 6 and this time they bring westerlies,
with southerlies for Northern Ireland ahead of a low.

GFS: http://www.wzkarten.de/pics/Rtavn1201.png
GFS is different to the European models in that although it shows a low to
the NE, it also has a secondary low west of the UK. This creates a col over
Scotland and westerlies elsewhere. On day 6 the secondary low moves
ESE'wards, over the Netherlands, leaving the UK under NW'lies. A col covers
the UK on day 7, with light winds for all.

GEM: http://www.wzkarten.de/pics/Rgem1201.gif
The Canadian run brings NW'lies for all, this time with a low over southern
Norway.

JMA: http://www.wzkarten.de/pics/Rjma1201.gif
JMA has complex low pressure to the NE and east, with NW'lies for the UK.
