My son lives in Westbourne and has been trying to get to work in Poole.
He's texted to say that his bus has taken 3/4 hour to do the first mile!

Roads etc., still running OK, including buses, but slow. visibility
similar to above. Haven't measured the 'official' rainfall equivalent
but will do a rough sample from my small stand-by gauge.

mistiness (600-800M); little additional depth, circa 1/2 to 1 cm at
most. OAT: 0.4°C. [ Isolated reports on radio of '6 inches'/which would
be ~15 cm, well to the north of us in the Cranborne Vale, but of course
can't verify that.]

I am told on good authority that there's over 5 cm down on the Solent
coastline too, Gosport/Lee on Solent usually miss it but not this
time.

7 to 9 cm here in West Fareham and counting... 0.0 deg C, no
significant drifting.

visibility still in fog limits but not due to the snowfall intensity.
Little 'new' snow again, so total amounts holding steady around 6 cm
mean with LOC pockets 7 or 8 cm, some settling now. Been clearing paths
and it's clear that a lot of heat is coming up from below.

From my stand-by gauge, the total PPN at 09Z (24hr up to then) = 11.9
mm. Doesn't truly relate to the snow depth as when the event started,
there was an extended period of sleet, and given the nature of the
'true' snow, it's 'flopped down' (i.e. settled) from its theoretical
maximum depth.

OAT: 0.3°C (note, coming down)

hovering just within fog limits (~900M). New depth since 09Z perhaps 1

at that time to around 5 cm.

no real extra depth but where I've cleared the snow, there's a shallow

slightly increased intensity of snow and general visibility reduction.
OAT: 0.4°C
Traffic still light; Wilts and Dorset buses have given up I think, but
YellowBus continue (both operating to/from Bournemouth but W&D have to
go on more country routes).

pellets by 1415Z, and there is very little PPN coming out of a grey sky
(though with markedly lifted base and visibility now at least 4 km).

Finally managed to apportion-out a rainfall ex five-inch gauge which
gives period 17/0900 to 18/0900Z = 11.9 mm: and up to my messing about
around 1400Z, another 7.1 mm ... total for the 'event' then 19.0 mm, but
as you can see from my depth reports [means 09Z to 15Z varying between 5
and 8 cm], nothing like a 10:1 ratio was produced in snow depth ...
though I fancy if the starting temperature had been lower (it was around
3degC) and the ground a lot colder (as per East Anglia for example),
then we would have had a much higher yield.

All-in-all though, a 'useful' event and certainly better than last winter!

A fascinating and absorbing set of reports... thank you for those.
It was particularly interesting to hear of your snow accumulating
at a similar rate to that of Romsey until around 1000Z when our
depths took a departure. Our level continued to climb to 12cm
in sub-zero temperatures while yours struggled to maintain 6cm
due to the slightly loftier temperatures in closer proximity to the
English Channel. It's amazing what even half a degree Celsius
difference can make.

Melting the snow up to 6pm has yielded 13.6mm of equivalent
rainfall for this event.

I note you were up even earlier than me this morning... by about
an hour.

My father at Wootton on the opposite side of the Solent from you
measured 6cm at a height of 40m amsl and less than a mile from
the coast. Deeper snow further inland on the Isle of Wight, if you
can call anything 'inland' on that island.
