Note: We're back at the time of year when people like to fool themselves
into thinking it's an hour later than it really is. As a result I have to
leave an hour earlier than before, hence this shorter analysis.

Here is a summary of the latest NWP output for noon (GMT) on Thursday.
Issued 0457z, 26/03/10.

The end of the working week will see a SW'ly flow over the UK with rain for
most, heaviest in the north and west. Over high ground in Scotland and Wales
snow is likely and that'll remain the case during the weekend as a low moves
in from the west, bringing rain to much of the UK.

Strong WSW'lies and WNW'lies cover the UK due to a deep low east of
Scotland. A new low approaches from the west on day 6, with southerlies for
all. The low moves NE'wards on day 7, leading to WSW'lies for all areas
except Scotland, which lies under SE'lies.

A deep low lies to the north, bringing SW'lies for all. A secondary low
moves in from the west on day 6, with southerlies as a result. Day 7 sees
low pressure over Scotland as well as England. Winds are strong WSW'lies in
the far south and generally light elsewhere.
