Here is a summary of the NWP output for noon on Wednesday.

The latter half of the working week will see a change to much colder
conditions over the UK, as low pressure moves SE'wards over the North
Sea. At this time of year, the flow is likely to be very unstable,
with heavy (and wintry) showers possible anywhere. Over the higher
ground of the north the showers are likely to fall as snow and
there's a chance (albeit a much lower one) of snow pretty much
anywhere. Settling snow is unlikely away from the north, however, due
to the strength of the sun at this time of year.

Though there have been many notable cases at this time of year and
later with heavy accumulations after dark. One that springs to mind was
on or about 20th April in, I think, the late 1970's when there was an
accumulation of 2-3 inches even in Central London
