Given the recent talk about 1000/500mb thickness it's perhaps
interesting to note that this snowfall is likely to occur in air
slightly warmer than 528DAM.

Fascinating. If I interpret that correctly, it looks as if it may have
influenced the forecast on the BBC just before 8pm, which tentatively
suggested that the Chilterns and east Midlands might have snow.
