Lukey, because the people on here are nationwide, not just in Solihull, and a bit of a damp squib for you today could mean that someone 30 miles further east has had a winterwonderland.
It is also the precursor to the temperatures dropping remarkably as the block sets in with the Easterlies. Models such as the GFS are using software that relies on a west-east atlantic flow, and struggle to cope with the vagaries of blocking and East winds.
The main model guidance seems to be moving away from a quick breakdown and snow could happen anywhere later this week, it is just an educated guess at this point, where that snow will fall, and if we have a batleground between atlantic and block, there could be snowfest anywhere.
Given the altitude of the West Midlands, it could well stick as well if it happens over you.
