Whatever it was it's gone now.
I'm just getting a completly unremarkable NW flow on that one.

Col,

if you have a gander at the ECMWF at T+240 you'll get the picture. Not quite
the 'perfect' setup that GFS had at T+384 last night. Pity I didn't save
that one!

I think the forecasting computers are deliberately taunting us...

Useful page, Joe. Notice the higher resolution GFS (0.5°) and WRF models are
indicating snow over parts over northern France and the higher ground over
the UK but even these models will struggle with this situation where a
change of precipitation type at the surface could well depend on a change of
1 degree (or less) in the boundary layer. Either way I strongly suspect
they're underplaying the snow risk over France.

1700Z issue Long TAFs for the various Paris airports have light sleet/snow
tomorrow evening. Closer to home there's a risk of snow at Leeds and sleet
at some of the elevated sites further south.

Thanks Jon. I'm getting increasingly excited about snow possibility on Dartmoor
now. I'm over 1000 feet up and a lot of the moor is over 1500 feet.
