Default Yellow snow warning

I'm a bit puzzled by the yellow snow warning that was issued this morning for
Wed/Thu. The southern limit of the warning area is approximately Southport to
north Manchester. Given the very unstable airmass and the forecast NW wind I
would have expected that the showers would penetrate much further south than
that, down into Staffordshire if the wind is a true NW'ly and across the Peak
District if there's more west in the wind. It seems odd that Blackpool is
explicitly included in the warning area but the W and NW facing uplands of
Staffordshire and Derbyshire aren't. In contrast, the current Peak District
forecast for Thursday predicts

"Wintry showers will be heavy and quite frequent, particularly in
western areas where snow will steadily accumulate"

which seems to be at odds with not being included in the yellow warning.

A lack of "joined-up" forecasting by the looks of it, but then what would I
know :-)

With the right airstream penetrating the Cheshire Gap there's nothing to stop snow showers getting through to the Home Counties.

Ah yes Norman, Yellow snow has a variety of attributes,
even if we discount the 'monks of St. Bernard'. Up here in
the north, it is usually associated with snow which covers
the flowering whins. In the last week, many of the whins
are breaking into flower.
