There's no end to it. This zonal spell of weather began around the
start of the last week in November and if this forecast proves
correct, the spell will be close to 6 weeks in length. The forecasts
of a cold December, that we had to endure from some quarters in early
November are now a distant, failed, memory. 2 months of the winter
left. It'll get cold and snow widely at some stage (probably) but
there's nothing, for most, on the 10-day horizon.

**At T240, on January 2nd 2012. the UK will still be under the
influence of zonal, Atlantic weather. Pressure will be higher to the
South of the UK than to the north. Temperatures will vary with the
position of the depressions which will continue to pass to the north
of Scotland - colder, with hill snow in their lee; mild and perhaps
very mild, as depressions approach. rainfall amounts will be above
average over the next 10 days, especially in the N and NW of Scotland,
where there will be occasional spells of gales. Frosts will be
confined to transient ridges and lowland snow will be absent, for
most**.

No blocking; very little chance of sledge weather for anyone living
below 250m. Sorry coldies, but you can do nothing about those
consistent charts.

You may be right but surely this does not meet your normally stipulated
model consistency criteria. There is absolutely no agreement from
January 2nd onwards in the ensembles so your normal advice would be to
ignore it.
