Here is a summary of the latest NWP output for noon on Thursday. Issued
0528, Christmas Day 2005.
The models show a wet and windy end to the year with rain sweeping in from
the west on Friday. With cold air over the UK on Thursday there's a small
chance of some significant snow/freezing rain before it turns back to rain,
although the models are bullish on precipitation being rain from the start.
Whatever the weather I'd like to wish everyone who reads this a happy and
peaceful Christmas.

Much of the UK lies under a col with light winds, although eastern England
is affected by NW'lies from a low over Denmark. Southerlies spread from the

SSW'lies for all at T+168 with the trough just to the west of Ireland.

The GFS brings low pressure over Ireland with a mixture of SSE'lies and

leading to strong to gale force westerlies for the UK. A trough moves
eastwards at T+168 with westerlies in advance and NW'lies following behind.
