The Met Office 120-hr MSLP forecast shows a strong NW'ly with a
WARM front across the country, moving SE. I've never seen this before
but it ties in well with the 96-hr prediction and appears not to be a
mistake. A minor cold pool precedes the front, which makes sense, but
the GFS prediction has the thickness decreasing northwards (deduced by
mental gridding).
You can get southward-moving warm fronts in winter when Atlantic
air pushes round the top of a High to the west but in this case the
origin of the warm air seems to be NW Russia. Most unusual, and
especially in July. I just can't picture what sort of weather it will
bring. Any comments, anyone?

It caught my eye too, Tudor. The warm front has been drawn close to the 12C
850mb WBPT with lower values (10-11C) to the south of it. The warmer air
emanating from Russia as you suggest. The associated modified fields
indicate patchy rain/drizzle, more especially over northern hills and
northern and eastern coastal areas.
