.... 2100Z ... lengthy period since above of NIL PPN, but recently
started up again: still slight; larger flakes now .. no impact
surfaces/visibility. OAT dropped from 1.7°C at 20Z to current 1.3°C.

A bit more over here in Hilton. Several colleagues did a runner from
work and are going to get fried tomorrow I think. The radar has pepped
up a colour recently but it is nearly passed I think.

The remarkable thing is that the Tuesday event seems to have
disappeared from the charts ( FNMOC for me) - which to me is
incredible. Must be very tricky to forecast therefore. Will seems to
refering to it ( or something) still

.... the trend looks to be 'on the way out' but I note that the cloud
tops are cooling (indicating some development as minor pulse of
cyclonic vorticity advection runs across the cloud mass), so we could
still get a covering here ... just making the surfaces damp atm.

.... it's back to a certain extent on the EC 12Z OP, which model is,
averaged over a reasonable period, consistently better than most.

'Testing the forecasters nerve' is a phrase that was used in another
context many years ago ... and probably applies this time around. A
lot of shuffling to and fro yet.

otherwise no impact (though the dampness will be important of course
as temperatures are easing down .. OAT now +1.0°C .. and cloud will
thin/clear progressively from a couple of hours time).

Hold it! Changed my mind! Just noted a rotation appearing (on the
radar) to start in the Channe ( I think that is what you are refering
to?)l and I am now wondering if this will throw up an arc during the
early hours over the coast roughly where we are.
The charts I look at on the soaring site do give a shallow low.

I note Will has suggested that low 'will be back!'. Anyway I am
packing everything into the car as must leave Dorset at noon no matter
what.

It is 'still' but possibly not as 'still' as Evershot appears to be
recently.....

.... just to summarise: a further few flakes around 2210Z, then
nothing; this morning all that is evident are a few, very small
patches / sprinkling of left-over flakes, and a few snow pellets mixed
in. Even the surfaces dried off to a large extent, so road ice not
really a problem.

Equivalent PPN (0.1 mm/just).
